PREFACE
The multi-country outbreak of mpox, which was detected in May 2022, has now caused almost ninety
thousand reported cases worldwide. Primarily affecting men who have sex with men, with cases first
appearing in Europe and spreading rapidly to the Americas and all regions of the world, including back
to Africa, the outbreak has underscored a key lesson: the virus can propagate rapidly in interconnected
sexual networks.
This outbreak compounded the longstanding neglected mpox situation in several African countries
where zoonotic spillover followed by initially limited person-to-person transmission was presumed to
be responsible for most cases. This neglect enabled the virus to exploit new modes of transmission
across different countries, such that that mpox is also now considered to be sexually transmissible.
The sustained decline of the multi-country outbreak can be attributed to effective risk communication
and community engagement for men who have sex with men and other groups at risk in countries
experiencing the introduction of the monkeypox virus. These efforts facilitated behavioural shifts
among persons at risk and increased vaccination uptake, where vaccines were available, providing
immunity for many. Some of the persons who were most at risk of exposure acquired mpox early on,
so their immunity also contributed to the decline.
Nonetheless, in a short period of time, mpox went from being a disease unknown to most people to a
public health emergency of international concern, characterized by a mode of transmission not
previously described, and about which there are still numerous unknowns. As long as global circulation
of the monkeypox virus persists, the potential for new outbreaks among people who have multiple sex
partners, including sex workers, remains. Furthermore, the risk of establishing new animal reservoirs
and viral evolution towards heightened transmissibility are continuous concerns.
In response to these looming risks, countries worldwide, irrespective of their current epidemiological
status, must unite to eliminate person-to-person transmission of mpox and prevent zoonotic spillover.
Lessons from the emergency phase of the response and research into the myriad unknowns regarding
the monkeypox virus and its interactions with the human body and human society will inform this
concerted campaign.
Throughout the declared public health emergency of international concern associated with the multi-
country outbreak of mpox spanning July 2022 to May 2023, countries’ response efforts were guided by
temporary recommendations issued under the International Health Regulations (2005) (IHR). As the
elimination phase unfolds, countries' preparedness and response actions can be steered by the
standing recommendations set forth under the IHR.
In this report, the Review Committee advises the Director-General on the contents of such
recommendations.
Members of this Review Committee came from all regions of the world, and were appointed to the
Committee for their expertise, their independence, and their commitment to global health. I thank
them for their work on this report, which will form a basis for the Director-General of the World Health
Organization (WHO) to issue standing recommendations for mpox to all States Parties to the IHR.

1. INTRODUCTION AND BACKGROUND
1.1 SHORT HISTORY OF THE EVENT
Mpox (monkeypox) is a viral infectious disease which ccommonly manifests with a skin rash or mucosal
lesions which can last 2–4 weeks, accompanied by fever, headache, muscle aches, back pain, low
energy, and swollen lymph nodes. While usually not severe, mpox may sometimes lead to grave
complications such as encephalitis or sequelae such as blindness. The frequency of complications varies
according to factors which include the virus clade, route of exposure, and underlying medical and
immune status of the patient. Mpox can result in death, with case fatality ranging from 0.2% to 10% of
cases in different contexts. The first case was identified in an infant in Africa in 1970.
In May 2022 an unprecedented outbreak of mpox began to spread rapidly in many countries in Europe
and the Americas, primarily through sexual contact among men who have sex with men. On 23 July
2022, pursuant to the provisions of the International Health Regulations (2005) (IHR), the Director-
General of the World Health Organization (WHO) determined that the multi-country outbreak of
monkeypox (later known as mpox) was a public health emergency of international concern (PHEIC).
By August 2023, 90 000 confirmed cases and 152 deaths had been reported to WHO from 113 countries
in all six WHO regions, with sustained human-to-human transmission. In addition, during this time,
thousands of suspected cases and among them hundreds of deaths were reported in Africa, while
access to diagnostics remains limited in many areas. During the year, the Director-General issued
temporary recommendations for States Parties to prepare for and respond to the outbreak.
The infectious disease mpox is caused by the monkeypox virus (MPXV), a DNA virus of the
Orthopoxvirus genus that transmits from person to person, and in parts of Africa, from animals to
people. Mpox can spread through physical contact with skin or mucosal lesions, body fluids or
respiratory secretions, or with contaminated materials including sharps or bedding. In enzootic areas,
contact with animals carrying the virus or consumption of wild game has led to infection with onward
transmission between people. Following eradication of smallpox (and the end of smallpox vaccination)
after 1980, mpox steadily emerged in Africa.
Outbreaks of mpox have thus historically occurred largely in West, Central and East African countries,
where the virus is enzootic, presumed to result from zoonotic spillover followed by limited human-to-
human transmission. Prior smallpox vaccination (with vaccinia virus) was often protective. However,
over the years, chains of transmission have lengthened, and since 2018, sporadic cases and clusters
have been detected elsewhere, largely linked to travel from endemic countries with limited onward
spread and imported animal-to-human transmission documented on one occasion. Two genetic clades
of MPXV exist, clade I and clade II, subdivided into clades IIa and IIb. Clade I MPXV occurs primarily in
Central and East Africa and has a case fatality ratio of 10%.
Clade II, sporadically found in West Africa with a significant outbreak in Nigeria ongoing since 2017, has
a case fatality of 1% or more in that context. Cases linked to travel from Nigeria reported since 2018
have been found to have clade IIb MPXV. The global outbreak of mpox that began in 2022 is also linked
to clade IIb MPXV, so far found only in humans, and has resulted in death in 0.2% of cases. Both virus
clades lead to similar clinical features. However, in the West African and global outbreaks, clade IIb has
been associated with a more frequent occurrence of rash presenting primarily as anogenital lesions,
leading to newly described clinical syndromes including extreme pain. Other newly described
conditions have included myocarditis, proctitis and recurrent cropping of skin lesions.
6
Since 2017, isolates of clade IIb virus have been characterized by genetic changes associated with
genome edits by the human protein, APOBEC3,1 suggesting adaptation of the virus outbreak strain to,
or propagation through, human-to-human transmission. It is important to note that patterns of
transmission with no apparent zoonotic source have also been occurring in Africa for many years. The
2022 - 2023 multi-country outbreak has been characterized by sustained human-to-human
transmission via direct skin-to-skin and sexual contact, with early transmission linked to amplifying
events involving sexual networks of men who have sex with men. The primary mode of transmission in
these networks was close contact during sex. Occasionally, household members, including children, of
persons with mpox acquired the infection through close contact. Health workers have been exposed
through occupational incidents. In Africa, women and children continue to represent a greater
proportion of cases than in countries experiencing the introduction of the MPXV. People living with HIV
have been disproportionately affected in both contexts. Risk factors for severe disease and death
include immune suppression due to advanced HIV disease or other cause, as well as young age under
5 years or older age above 65.
Response efforts were rapidly put in place and WHO worked with governments, communities, and
stakeholders worldwide to develop and implement effective strategies to stop the outbreak. WHO
published technical guidance, public health advice and research protocols; provided diagnostic test kits
to over 90 countries and supported harmonization of testing protocols and procedures; established
reserves of therapeutics for compassionate or emergency use; and supported coordination of vaccine
supply through bilateral or multilateral arrangements. Community responses to share information,
combat the stigma associated with mpox, and support integration of services with HIV/STI and other
health services and community activities have been crucial to the outbreak response. However,
important gaps remain in understanding patterns of transmission, particularly in Africa. Any State Party
may also now experience importation of mpox from the territory of any other State Party, as well as
local spread. Mpox can occur anywhere, and introduction or re-introduction of the virus that causes
mpox remains an ongoing risk for all countries.
The global outbreak has shifted the understanding of mpox as an infectious disease that spreads
between people. In addition to ongoing risks of human-to-human transmission, some countries will
continue to have some outbreaks related to zoonotic transmission.
The multi-country outbreak clearly highlighted the continuing inequity in access to diagnostics,
vaccines and therapeutics within countries and between regions. While patterns of transmission of
mpox without any confirmed or apparent zoonotic source had been noted in Africa for years, prior to
2022, efforts to develop specific counter-measures for mpox were limited. Studies of diagnostics,
vaccines and therapeutics were for example focused primarily on smallpox preparedness concerns,
such as ability to detect variola virus, vaccine safety or feasibility of use of tecovirimat in remote
locations, rather than effectiveness in response to outbreaks of mpox in under-resourced settings.
In the wake of the multi-country outbreak, large and widening gaps remain. Access to diagnostics in
resource-limited and/or remote areas remains very challenging. For example, in the Democratic
Republic of the Congo (DRC), only about 10% of reported suspected cases are tested and of these, in a
recent update from the country, three quarters of suspected cases tested positive for mpox, a high
positivity rate which suggests under-ascertainment of cases. Likewise, while progress in the
1 APOBEC3 (apolipoprotein B mRNA editing enzyme, catalytic subunit 3) is a human enzyme family that plays a role in
generating virus mutations. How emerging MPXV strains will evolve remains unknown. These mutations may help guide future
development of vaccines or therapeutics.
7
authorization of smallpox vaccines for use in preventing mpox has been rapid and vaccine effectiveness
data are emerging, access to vaccines remains limited to high income, self-procuring countries or
collective entities procuring vaccines for their members, such as through the Commission of the
European Union or the PAHO Revolving Fund for vaccines. Antiviral agents such as tecovirimat and/or
brincidofovir, developed to treat smallpox, have been used to treat mpox in a few countries, and further
studies are underway. Nevertheless, highlighting inequities once again, access to tecovirimat and its
clinical use has been limited almost exclusively to high income, self-procuring countries or within the
context of ongoing clinical studies and is otherwise not available in lower resourced countries.
There is a need for longer-term attention and support to address this emerging disease, with robust,
proactive and sustainable mpox control, particularly where mpox continues to occur regularly, to stop
outbreaks and prevent resurgence of global spread. The Emergency Committee established under the
International Health Regulations (2005) in June 2022 therefore recommended that all countries
develop and implement plans to control mpox, eliminate human-to-human transmission, and reduce
the risks of zoonotic transmission. To meet these needs, WHO is preparing a Global Strategic
framework for enhancing control and achieving elimination of human-to-human transmission of mpox
(2023-2027) which is undergoing a consultative process with WHO Member States, partners and
stakeholders. This framework outlines the goal to achieve sustained elimination of human-to-human
transmission of mpox, which is underpinned by three objectives: to 1) achieve control of mpox
outbreaks in every context, 2) advance mpox research and access to countermeasures and 3) minimize
zoonotic transmission. The WHO Secretariat presented to the Review Committee a draft of the
framework, hereafter referred to as Draft Global Strategic Framework for mpox (2023-2027).
1.2 MANDATE OF THIS REVIEW COMMITTEE
The Review Committee regarding standing recommendations for mpox was convened by the Director-
General of WHO pursuant to Part IX – Chapter III – The Review Committee of the IHR (Articles 50-53)
of the IHR. The IHR are a binding instrument of international law that entered into force in 2007. Their
196 States Parties include all 194 Member States of WHO, plus the Holy See and Liechtenstein.
Pursuant to Articles 50.1(b) and 53 of the IHR, this Review Committee is providing its views and
technical advice to the Director-General with respect to standing recommendations for mpox, as
proposed by the Director-General. The Review Committee functions in accordance with the WHO
Regulations for Expert Advisory Panels and Committees.
This would be the second time that these specific provisions of the IHR are being applied; as such, it is
understood that further details in support of the Terms of Reference of the Committee may be provided
as experience is gained.
1.3 METHODS OF WORK
The Review Committee was convened by the Diretor-General of WHO on 27 July 2023. It was expected
to meet virtually and to deliver their final report to the Director-General before 10 August 20232, when
2
On 9 August 2023, in his opening remarks at the WHO virtual press conference on global health issues, the
Director-General of WHO indicated that “The Review Committee is also discussing standing recommendations for
mpox, which it will deliver later this week.”
8
the current temporary recommendations, issued by the Director-General after the termination of the
PHEIC related to the multi-country outbreak of mpox, have come to an end.
The Review Committee includes 20 Members, selected from the IHR Roster of Experts or other WHO
Expert Advisory Panels and Committees, representing a wide range of expertise, from all six WHO
regions, in accordance with Articles 47 and 50 of the IHR. Ahead of their convening, the Committee
was provided with a draft agenda, its Terms of Reference and mandate under the IHR, as well as with
the draft standing recommendations and global long-term risk assessment for mpox, prepared by the
WHO Secretariat.
The Review Committees met virtually in both, open and closed sessions as follows:
- 27 July 2023 – First closed session, opened by the Director-General via a pre-recorded video.
The opening remarks are available here. The Review Committee were reminded of their
obligations under the WHO Rules of Procedures for Advisory Panels and Committees, and no
conflict of interests were reported. In accordance with the Rules of Procedures, the Committee
selected its officers: as Chair Professor Preben Aavitsland, from Norway; as Vice-Chair Mister
Andrew Forsyth, from New Zealand; and as Rapporteur, Dr Inger K. Damon, from the United
States of America.
The Review Committee proceeded then to consider the proposed standing recommendations
for mpox, presented by the WHO Secretariat, who also provided an update of the
epidemiological situation, and the long-term risk assessment.
- 27 July 2023 – Open joint session of the Review Committees regarding standing
recommendations for COVID-19 and Review Committees regarding standing
recommendations for mpox. In accordance with Article 51.2 of the IHR, the two Review
Committees met with States Parties, the United Nations, other UN specialized agencies,
relevant intergovernmental organizations and non-State actors in official relations with WHO.
- 7 August 2023 – Second closed session. After electronic communications to elaborate their
report, the Review Committee reconvened virtually to finalize and adopt it.
This report of the Review Committee contains its views and technical advice to the Director-General
regarding the proposed standing recommendations, and was transmitted on 16 August 2023 to the
Director-General for consideration and decision. Any standing recommendation that the Director-
General may be issuing, would enter into effect upon issuance.
To that effect, pursuant to Article 53(f) of the IHR, the Director-General shall communicate to States
Parties any standing recommendation, together with the views and technical advice of the Review
Committee. Furthermore, in accordance with Article 53(e)and Article 53(g), the Director-General shall
communicate the Review Committee’s views and technical advice, as well as standing
recommendations, to the Seventy-seventh World Health Assembly in May 2024 for its consideration.
1.4 EMERGENCY COMMITTEE, PUBLIC HEALTH EMERGENCY OF
INTERNATIONAL CONCERN, AND TEMPORARY RECOMMENDATIONS
The Director-General of WHO first convened an Emergency Committee under the IHR on 23 June 2022,
to advise him on whether the multi-country outbreak of monkeypox, constituted or not a PHEIC. At
that time, the Director-General, following the advice of the Emergency Committee, determined that
9
the event did not constitute a PHEIC. The Committee was reconvened on 21 July 2022, when divergent
views were noted as to whether to advise the Director-General that the event constituted a PHEIC. The
Director-General, taking into account considerations provided by the Emergency Committee, as well as
other elements as per Article 12.4 of the IHR, on 23 July 2022, determined that the event constituted
a PHEIC and issued temporary recommendations, in accordance with Articles 1, 15, 17 and 18 of the
IHR. The temporary recommendations were reviewed every three months.
At its 5th meeting, held on 10 May 2023, the Emergency Committee advised the Director-General that
in its views the event no longer constituted a PHEIC and suggested that standing recommendations
under the IHR may provide a better tool to manage the long-term public health risks posed by MPXV.
On 11 May 2023, on the advice of the Emergency Committee, the Director-General terminated the
PHEIC related to the multi-country outbreak of mpox. In accordance with Article 15 of the IHR, the
Director-General continued to issue temporary recommendations after the termination of the PHEIC,
at the advice of the Emergency Committee, and these recommendations expired on 10 August 2023.
1.5 LEGAL BASIS IN THE INTERNATIONAL HEALTH REGULATIONS (2005)
The purpose and scope of the IHR are set out in Article 2 - Purpose and scope as follows “[…] to prevent,
protect against, control and provide a public health response to the international spread of disease in
ways that are commensurate with and restricted to public health risks, and which avoid unnecessary
interference with international traffic and trade.”
To that effect, the issuance by the Director-General of both temporary recommendations, in
association with a PHEIC, and standing recommendations represents some of the tools offered by the
IHR to manage public health risks, including curbing their international spread and mitigating their
impact. Public health risks are defined in Article 1 - Definitions as “likelihood of an event that may
affect adversely the health of human populations, with an emphasis on one which may spread
internationally or may present a serious and direct danger.”
The IHR include the following specific provisions related to standing recommendations:
The standing recommendations are defined in Article 1 - Definitions as “non-binding advice issued by
WHO for specific ongoing public health risks pursuant to Article 16 regarding appropriate health
measures for routine or periodic application needed to prevent or reduce the international spread of
disease and minimize interference with international traffic.”
Article 16 authorises the Director-General with the discretion to issue standing recommendations.
Article 16 - Standing recommendations
WHO may make standing recommendations of appropriate health measures in accordance
with Article 53 for routine or periodic application. Such measures may be applied by States
Parties regarding persons, baggage, cargo, containers, conveyances, goods and/or postal
parcels for specific, ongoing public health risks in order to prevent or reduce the international
spread of disease and avoid unnecessary interference with international traffic. WHO may, in
accordance with Article 53, modify or terminate such recommendations, as appropriate.
Article 17 includes the criteria that Director-General shall consider when issuing, modifying or
terminating any standing recommendations.
10
Article 17 - Criteria for recommendations
When issuing, modifying or terminating temporary or standing recommendations, the Director-
General shall consider:
(a) the views of the States Parties directly concerned;
(b) the advice of the Emergency Committee or the Review Committee, as the case may
be;
(c) scientific principles as well as available scientific evidence and information;
(d) health measures that, on the basis of a risk assessment appropriate to the
circumstances, are not more restrictive of international traffic and trade and are not
more intrusive to persons than reasonably available alternatives that would achieve
the appropriate level of health protection;
(e) relevant international standards and instruments;
(f) activities undertaken by other relevant intergovernmental organizations and
international bodies; and
(g) other appropriate and specific information relevant to the event. [...].
Article 18 provides a list of public health measures that may be included in standing recommendations.
Article 18 - Recommendations with respect to persons, baggage, cargo, containers,

2. THE MULTI-COUNTRY OUTBREAK OF MPOX
2.1 CURRENT WHO RISK ASSESSMENT OF THE MPOX SITUATION
This section is based on the Long-Term Risk Assessment for mpox provided by the WHO Secretariat to
the Review Committee in advance of the first session of its meeting.
According to the assessment by the WHO Secretariat, the global public health risk associated with
mpox is low in the general population. In African settings where mpox continues to occur regularly,
the risk for the general population is moderate, higher than elsewhere around the world. For men who
have sex men and for sex workers, the risk is assessed as moderate in all settings and contexts.
Since the beginning in May 2022 of the ongoing outbreak of mpox largely associated with clade IIb
lineage B MPXV, 113 countries in all six WHO regions have reported cases. From 1 January 2022 to
25 July 2023, 88 600 confirmed and 1087 probable cases, including 152 confirmed deaths, have been
reported to WHO (CFR: 0.17%). This is the largest ever recorded mpox outbreak, and 99 of the 113
reporting countries have detected mpox for the first time.
The number of cases peaked in July-August 2022, followed by a steady decline until March 2023 and a
low plateau of around 100 new confirmed cases reported per week continuously since, which is now
rising again. The virus continues to circulate globally. Sixteen countries have reported cases in the last
21 days (the maximum incubation period), with some reporting mainly travel-related cases and others
experiencing sustained human-to-human community transmission. In 2023, some countries have
reported cases for the first time and sustained person-to-person transmission has been reported in the
South-East Asia and Western Pacific Regions, including most recently in mainland China. In Europe and
the Americas, sporadic cases and outbreaks continue. Transmission continues to be reported in
countries where MPXV has historically been circulating in the African Region, especially Nigeria and
DRC. The upward trend of reported suspected cases and deaths in the DRC continues unabated, with
the highest number of suspected cases ever reported (6031 cases) as of mid-July 2023.
The 2022-2023 multi-country mpox outbreak has affected mainly men 18-49 years of age (90% of cases;
70 112 / 78 168) and, among those with available information, the majority (84%; 26 111/31 031) have
self-identified as gay men or bisexual men or reported same-sex activities. Transmission through sexual
contact has also been described in settings in the African region: in Nigeria, recent studies have shown
that heterosexual transmission plays an important role. Overall, countries in West, Central and East
Africa with previous history of mpox present cases among younger age groups, including children and
adolescents, which also suggests different transmission dynamics. This for example is particularly true
of the first ever reported outbreaks of mpox in refugee camps, in Sudan in 2022, where children under
the age of five years were most affected, as well as older children and some adults, from which
specimens were confirmed to have clade I MPXV. This supports observations that the range of MPXV
may be expanding in Central and East Africa. Countries in the African region have also observed an
increase in cases in the last year compared to previous years.
The general clinical presentation of mpox associated with clade II MPXV in the multi-country outbreak
has been less severe compared to what was previously described for cases in West Africa. The reasons
for this are not fully understood but may in part be due to better case ascertainment (detection) of
milder cases during the peak of the outbreak. Nevertheless, there have been people hospitalized for
very severe mpox disease, as well as deaths. Among reported cases of mpox for whom the information
is available, around half were people living with HIV. People living with HIV who are immunosuppressed
13
due to advanced or uncontrolled disease are more likely to present severe forms of mpox and have a
greater risk for hospitalization and death. While the case fatality ratio (CFR) in the multi-country
outbreak remains under two deaths per thousand cases, the CFR in West (>1%) and Central Africa
(around 10%) remain at the higher levels previously described. While the degree of case ascertainment
in Central Africa is uncertain, clade I MPXV has also been shown in animal studies to be more virulent
than clade II.
With respect to the risk of ongoing zoonotic exposure there are many uncertainties. While various small
mammals are susceptible, including rope squirrels, gambian rats and dormice as well as species of
monkeys and other primates, the origin and animal reservoirs of MPXV are not known. It may be that
several animals support MPXV circulation in a natural lifecycle with complex interactions of reservoir
hosts and incidental species, from which virus shedding may lead to human exposure. This was the
case in the outbreak of mpox in the U.S. in 2003, where North American prairie dogs were the primary
transmitting species. Some outbreaks in human populations have been linked to contact with squirrels
or monkeys or consumption of their meat, particularly in Central Africa.
Based on the current available information, WHO assesses that the public health risk of mpox among
men who have sex with men, and among sex workers is moderate. The risk for the general population
at the global level is assessed as low. However, the risk to the general population including women and
children is higher in African contexts where mpox continues to occur regularly, modes of transmission
are less well understood, and the origins of outbreaks are largely unknown. The individual-level risk is
largely dependent on individual factors such as exposure risk and immune status.
While the epidemiological situation appears to improving globally, this is not the case in countries with
new outbreaks or in Africa where case counts are steady or continue to rise, representing higher risk
in those countries and continuing risk of spread from Africa to other parts of the world.
2.2 ASSESSMENT BY THE REVIEW COMMITTEE OF THE CURRENT AND
FUTURE MPOX SITUATION
In the early months of 2022, the MPXV was found to have entered networks of men who have sex with
men in Europe and North America and spread rapidly through intimate or sexual contact within those
networks, including through several international gatherings where multiple sexual contacts occurred.
Several factors seemed to drive transmission in this group: new or multiple sexual partners,
amplification of the outbreak during such events, the rather long infectious period typical of mpox, and
greater risk of poor outcomes in people who are immunocompromised.
Outside those networks, spread of the disease was limited, concerning primarily close contacts in the
household, including some children, and in a few cases health workers through occupational incidents.
The outbreak reached a peak in the Europe and North America in mid-2022 followed by slower declines
in the Americas. The virus continues to circulate globally. Sixteen countries that experienced the
introduction of MPXV have been reporting new cases in the last 21 days, with some reporting mainly
travel-related cases and others newly experiencing sustained community transmission. Transmission
also continues to be reported in the African Region, particularly but not exclusively in Nigeria and the
DRC. In addition, in recent months, countries that experienced the introduction of MPXV have reported
cases for the first time, including most recently in mainland China. In Europe and the Americas, sporadic
cases and outbreaks continue.
14
The reasons for the decline after August 2022 in the Northern hemisphere were mainly effective risk
communication and community engagement, which all led to behaviour change among people at risk,
and immunity due to infection or vaccination among those at highest risk of exposure and onward
transmission. This year’s festival season in Europe has led to smaller outbreaks in several cities.
A key lesson from the first year of the multi-country outbreak is that the virus can transmit rapidly in
social and sexual networks of men who have sex with men (and who have multiple partners), and
infrequently spreads outside this group. However, the situation in countries in Africa may be quite
different, given the mixed modes of transmission described, including heterosexual transmission and
spread within families. The first report of sexual transmission of clade I MPXV among men who have
sex with men is also concerning.
Based on current information, the Review Committee concurs with the WHO assessment that the
public health risk of mpox for men who have sex with men and for sex workers in all contexts is
moderate, while at the global level the overall public health risk is low. In addition, the Committee
concurs that the risk to the general population in a group of countries in Africa where mpox continues
to occur regularly is higher than at the global level due to many factors outlined above, and that this
also represents a risk for continuing or renewed global spread.
The experience from the last years is that outbreaks can be managed effectively through rapid case
detection, case isolation, contact tracing, effective risk communication (about symptom recognition
and risk behaviours) and community engagement, as well as treatment and vaccination. This means
that outbreaks may be stopped, and elimination of human-to-human transmission is within reach. The
outlook for stopping outbreaks in enzootic-endemic contexts and preventing future spread outside
these contexts is less certain due to limited understanding of how the circulation of the virus in wildlife
leads to zoonotic infections and contributes to ongoing human-to-human transmission. There remain
many other uncertainties, including the sustainability of behaviour change, the degree and duration of
immunity following infection or vaccination, the potential role of virus evolution, the efficacy of
antivirals.
WHO has presented to the Review Committee three scenarios for the future of mpox in humans that
were regarded as useful by the Committee. In the best-case scenario the disease comes under control
and human-to-human transmission is eliminated in all contexts. This is the goal of the Draft Global
Strategic Framework for mpox (2023-2027). In the intermediate-case scenario the virus continues to
spread in endemic settings and at a slow pace globally, while in the worst-case scenario the virus
spreads extensively.
The two latter scenarios may be influenced or characterized by the following events:
• Endemicity: without sustained action, the virus will continue to circulate in the groups affected
to date, including among sex workers who also face social barriers to health services. There
will be a need for continuous efforts to stop outbreaks, including in children, outside of these
groups, particularly where the disease already occurs regularly. The risk of international spread
continues from these outbreaks.
• Enzootic circulation: There is a risk of viral spill-back from humans to animals, with potential
for the formation of animal reservoirs in new countries. This risk increases with the duration
of the multi-country outbreak. Currently unknown animal reservoirs represent a constant risk
of zoonotic infection, new outbreaks and international spread.
• Evolved virus: The mpox virus has entered a new ecological niche, animal or human, where
there may be an evolutionary pressure towards greater intrinsic transmissibility, immune
15
evasion or both. The virus’ ability to undergo such adaptation is largely unknown. Under these
circumstances the risk of international spread will continue or possibly increase.
In order to avoid these negative scenarios, standing recommendations may be needed to stimulate
efforts in all countries to eliminate human-to-human transmission of mpox.
2.3 DRAFT WHO GLOBAL STRATEGIC FRAMEWORK FOR ENHANCING
CONTROL AND ACHIEVING ELIMINATION OF HUMAN-TO-HUMAN
TRANSMISSION OF MPOX (2023-2027)
Rapid case detection, isolation, contact tracing, risk communication and community engagement,
treatment and preventive vaccination are all essential to manage mpox outbreaks and move towards
elimination of human-to-human transmission. It is essential to create and tailor messages to different
local contexts, population groups at risk and modes of transmission, including where activities may be
criminalized or subject to stigma. It is essential to have testing services for mpox readily available, and
to integrate mpox into existing health programmes and services. Genomic sequencing capacity is also
essential to monitor the virus spread and any genetic changes.
Preventive vaccination for people at risk, including from occupational exposure, is not available in
virtually all low- and middle-income countries. Even in countries that experienced the introduction of
MPXV, access is limited. It is thus necessary to improve access to mpox vaccines globally and develop
vaccination strategies locally.3
Throughout the multi-country outbreak, WHO has supported States Parties with temporary
recommendations and advice to address it. In July 2023, the WHO Secretariat initiated a consultation
regarding the Draft Global Strategic Framework for mpox (2023-2027), outlining the strategy until
20274. The plan is meant to support countries in eliminating human-to-human transmission of mpox in
all contexts, including where some outbreaks may be linked to zoonotic spillover events. The Draft
Framework document presents its goals and objectives as follows:
“The overarching goal of the next phase of mpox prevention and response is to achieve
sustained elimination of human-to-human transmission of mpox.”
“The objectives of the global mpox elimination strategy are to:
(1) Achieve control of mpox outbreaks in every context.
(2) Advance mpox research and access to countermeasures.
(3) Minimize zoonotic transmission.”
Elimination of human-to-human transmission is defined as the absence of new cases (without any
travel history or zoonotic exposure) for at least three months in the presence of adequate surveillance.
The Draft Framework outlines four guiding principles: i. Support for community leadership; ii. Respect
for equity and human rights; iii. Context-specific collaboration and integration of mpox prevention and
care in other health programmes and services, and iv. Commitment to continuous learning. The Draft

16
Framework suggests that most countries or sub-national areas fall into one of four epidemiological
contexts which serve as starting points for integrated national planning for mpox.
• Context A: Areas reporting sporadic cases or sustained community transmission primarily
linked to sexual transmission, mainly among men (e.g., Europe and the Americas in 2022-2023,
Asia and the Pacific since mid-2023).
• Context B: Mixed modes of transmission, continuous over time, particularly affecting urban or
peri-urban areas, in which cases are more evenly distributed between men, women and
children with known or presumed person-to-person transmission (e.g., primarily urban areas
in West and Central Africa).
• Context C: Mixed modes of transmission, including episodic or recurrent outbreaks, often in
rural areas, involving person-to-person transmission and on some occasions potentially linked
to presumed zoonotic spillover events (e.g., primarily Central and East Africa).
• Context D: No reported cases, including consideration of areas from which travel-related cases
are reported by other jurisdictions.
The Draft Framework presents three priorities:
• Coordinated planning to ensure sustainable long-term action.
• Integration of mpox activities with relevant health, laboratory and community-based
programmes rather than “standalone” vertical mpox elimination and control plans.
• Strengthened global support for access to diagnostic tests, vaccines and therapeutics,
development of a research agenda, and WHO assistance to State Parties.
The Draft Framework sets out proposed mpox control and elimination phases and associated criteria
for consideration by regions and countries and provides specific domains in which operational planning
should be carried out. Suggestions for integration of planning and response activities are offered for
each domain, as well as a proposed monitoring and evaluation framework.

3. TECHNICAL ADVICE OF THE REVIEW COMMITTEE ON PROPOSED
STANDING RECOMMENDATIONS
3.1 NECESSITY, APPROPRIATENESS, AND SCOPE OF STANDING
RECOMMENDATIONS
Necessity and appropriateness of standing recommendations
Since the entry into force of the 2005 revision of the IHR, the Director-General has issued standing
recommendations only once5. There are several reasons why the Review Committee considers that
standing recommendations may be issued for mpox to all States Parties:
• While the PHEIC associated with the multi-country outbreak of mpox was terminated and the
incidence of disease in countries that experienced the introduction of MPXV is now far lower
than during the peak one year ago, this outbreak for the first time demonstrated the potential
for a global mpox epidemic driven by sexual transmission. Uncertainty remains concerning the
future trajectory and geographic expansion of the outbreak.
• In the African context where mpox has occurred since first discovered in 1970 and with rising
incidence in recent years, there is no clear downward trend: Nigeria where the multi-country
outbreak appears to have originated continues to report confirmed cases. The upward trend
of reported suspected cases in the DRC continues unabated, with the highest number of
suspected cases ever reported already in mid-2023. The emergence of clade I MPXV in Sudan,
which had not previously reported mpox, is also concerning. Other countries in the region
continue to report cases.
• The historical neglect of mpox in the African region and by the wider global community, as
reflected in the perennial inequity of access to vaccines, therapeutics, and diagnostics that
occurred during the multi-country mpox outbreak (which was determined to be a PHEIC once
the outbreak affected non-endemic countries), could be addressed by the issuance of standing
recommendations, in order to maintain interest globally in this previously under-appreciated
health problem, and especially to spur positive action in mpox endemic areas.
• Although the risk of severe disease and death has been low in the multi-country outbreak,
mpox may in some patients be a very severe disease, in particular in persons with immune
suppression, including those with untreated HIV infection. There is a high prevalence of HIV
disease in some communities of men who have sex with men, and in some heterosexual
populations in the African region. In the African context, the reported case fatality of mpox has
been up to 10 percent with small children being most at risk of death.
• There is a risk that the virus adapts to humans, resulting in more efficient human-to-human
transmission. This may alter the risk considerably.
• While the mpox virus belongs to an important virus family, there are myriad unknowns
regarding mpox, including the spectrum of clinical presentation, risk factors for severe disease,
efficacy and effectiveness of vaccines and antivirals, degree and duration of immunity
following infection or vaccination, routes of transmission, virus biology and evolution, and
5
More information on standing recommendations is available at: https://www.who.int/teams/ihr/standing-
recommendations [Accessed on 15 August 2023]
18
zoonotic reservoirs and intermediate hosts. These unknowns make it difficult to assess the risk
with high confidence.
• When the Emergency Committee after its meeting on 10 May 2023 advised the Director-
General to lift the PHEIC determination of mpox, it also advised him that “Standing
Recommendations under the IHR would now be a more appropriate tool to manage the
immediate, short and long-term public health risks posed by mpox”. The Director-General
followed this advice with the intention of issuing standing recommendations.
• The use of standing recommendations will help with the transition from the emergency phase
of the response, which included the use of temporary recommendations, to a sustainable long-
term strategy towards elimination, as outlined in the Draft Global Strategic Framework for
mpox (2023-2027) (see section 2.3) where States Parties are stimulated to keep up their
interest, awareness, and public health response to mpox so that elimination can be achieved.
However, the Review Committee acknowledged that there are reasons why standing recommendations
may not be considered necessary and appropriate for mpox:
• Although the mpox situation is a “specific, ongoing public health risk” as per Articles 1 and 16
of the IHR, the level of risk assessed by WHO for the general population globally may be too
low to justify standing recommendations.
• WHO guidance through technical advice to States Parties might be sufficient, rather than
issuing standing recommendations. The Draft Global Strategic Framework for mpox (2023-
2027) may stand alone without the enhancement of standing recommendations.
• States Parties need to pay attention to several disease risks. Issuance by WHO of standing
recommendations with respect to mpox might reduce focus on other national disease
priorities at a time when the health impact of mpox is small in most settings and the risk
assessed as low or moderate.
• The issuance of standing recommendations for mpox may set a precedent and lead to
proposals for standing recommendations for several other diseases, for which the long-term
consequences, for better or for worse, for global public health cannot at present be known.
After deliberating on the above-mentioned reasons and hearing a range of views from Committee
Members, the majority of the Committee was of the opinion that, in the current context, issuing
standing recommendations is necessary and appropriate and can be expected to prove useful for
managing the current risk posed by mpox and for reaching the goal of eliminating human-to-human
transmission. The Committee’s majority provides, in Section 3.2, a set of proposed standing
recommendations for consideration by the Director-General, and, in Section 3.3, its views and advice
on the duration of the standing recommendations that the Director-General may issue.
One Member of the Review Committee, pursuant to Article 52.2 of the IHR, provided the following
views underpinning his divergence from the Committee’s majority.
Recognizing that the multi-country mpox outbreak has been sustained mainly by sexual contact, the
expert deemed that it would be hard to justify the necessity of issuing standing recommendations, for
the following reasons: Firstly, the PHEIC associated with multi-country of mpox was terminated on 11
May 2023. Secondly, the global incidence of cases has decreased considerably in the last year, the case
fatality of mpox is low and WHO’s current risk assessment for the general population is low in the
general population globally. Thirdly, Member States’ compliance with standing recommendations may
19
pose an additional technical and financial burden to the public health systems in member states,
especially in low- and middle-income countries, whose underfinanced public health resources could
otherwise be directed towards other infectious disease threats. This expert recommended that WHO
instead encourages Member States to implement the WHO Global Strategic Framework for Enhancing
Control and Achieving Elimination of Human-to-human Transmission of Mpox (2023-2027) when
published.
Scope of the standing recommendations
The Review Committee discussed the scope of the proposed standing recommendations. Both of the
following interpretations were represented among the Members of the Review Committee.
A narrow interpretation of the scope of relevant articles of the IHR, especially 16, 17 and 18, is that
recommendations should be concerned with only measures that directly “reduce the international
spread of disease and avoid unnecessary interference with international traffic” (Article 16). Article 18
lists examples of such measures. Furthermore, standing recommendations should be specific and
relevant to the particular disease and risks associated with it and not generic recommendations, e.g.
regarding strengthening of health systems or surveillance systems in general.
A broad interpretation of the scope of the same articles is that the prevention and control of disease,
including inside individual States Parties, could indirectly serve to reduce international spread as well.
The Committee noted that temporary recommendations of similar scope, which are not explicitly listed
in Article 18, have been issued by the Director-General in relation to the PHEIC associated with the
multi-country outbreak of mpox.
The Review Committee recalled that mpox was and still is a neglected disease. Occurring for decades
mainly in a few African countries, mpox is in fact so neglected, that it is not even on the WHO list of
neglected tropical diseases6,7. The limited efforts to develop diagnostic tests, vaccines and therapeutics
were focused almost entirely on the global health security consideration of smallpox preparedness,
with limited assessment of the needs of countries and communities to prevent, control and respond to
mpox. During the emergency in 2022-2023 inequity in access to medical countermeasures continued.
The Committee advised that the standing recommendations should be guided by the public health risk
posed by mpox. Further, the Review Committee advised that the standing recommendations should be
in line with Articles 3, 42 and 44 of the IHR.
3.2 TECHNICAL ADVICE ON PROPOSED STANDING RECOMMENDATIONS
Based on the proposed standing recommendations presented to the Review Committee in advance of
its first session, the formulation of the standing recommendations enumerated below reflects the
technical advice of the Review Committee’s majority.
The Committee advises that the standing recommendations should apply to all States Parties and
should be adapted to national and local contexts as appropriate.

A. States Parties are recommended to develop and implement national mpox plans that build on the
Draft Global Strategic Framework for mpox (2023-2027)8. The draft outlines critical actions to sustain
control of mpox and achieve elimination of human-to-human transmission in all contexts through
coordinated and integrated policies, programmes and services. Actions are recommended to:
1. Incorporate lessons learned from evaluation of the response (such as through intra- or after-
action reviews) into related plans and policies in order to sustain, adapt, and promote key
elements of the response and inform public health policies and programmes.
2. Aim to eliminate human-to-human transmission of mpox by anticipating, detecting, preparing
for and responding to mpox outbreaks and taking action to reduce zoonotic transmission, as
appropriate.
3. Build and retain capacity in resource-limited settings, and among marginalized groups, where
mpox transmission continues to occur, to improve understanding of modes of transmission,
quantify resource needs, and detect and respond to outbreaks and community transmission.
B. States Parties are recommended to, as a critical basis for actions outlined in A in support of the
elimination goal, establish and sustain laboratory-based surveillance and diagnostic capacities to
enhance outbreak detection and risk assessment. Actions are recommended to:
4. Include mpox as a notifiable disease in the national epidemiological surveillance system.
5. Strengthen diagnostic capacity at all levels of the health care system for laboratory and point
of care diagnostic confirmation of cases.
6. Ensure timely reporting of cases to WHO, as per WHO guidance and Case Reporting Form, in
particular reporting of confirmed cases with a relevant recent history of international travel.
7. Collaborate with other countries so that genomic sequencing is available in, or accessible to,
all countries. Share genetic sequence data and metadata through public databases.
8. Notify WHO about significant mpox-related events through IHR channels.
C. States Parties are recommended to enhance community protection through building capacity for
risk communication and community engagement, adapting public health and social measures to local
contexts and continuing to strive for equity and build trust with communities through the following
actions, particularly for those most at risk. Actions are recommended to:
9. Communicate risk, build awareness, engage with affected communities and at-risk groups
through health authorities and civil society.
10. Implement interventions to prevent stigma and discrimination against any individuals or
groups that may be affected by mpox.
8
The Review Committee acknowledges the draft status of the Draft Global Strategic Framework for mpox (2023-
2027), which was provided to the Committee as background document to support its deliberations.
21
D. States Parties are recommended to initiate, continue, support, and collaborate on research to
generate evidence for mpox prevention and control, with a view to support elimination of human-
to-human transmission of mpox. Actions are recommended to:
11. Contribute to addressing the global research agenda to generate and promptly disseminate
evidence for key scientific, social, clinical, and public health aspects of mpox transmission,
prevention and control.
12. Conduct clinical trials of medical countermeasures, including diagnostics, vaccines and
therapeutics, in different populations, in addition to monitoring of their safety, effectiveness
and duration of protection.
13. States Parties in West, Central and East Africa should make additional efforts to elucidate mpox-
related risk, vulnerability and impact, including consideration of zoonotic, sexual, and other
modes of transmission in different demographic groups.
E. States Parties are recommended to apply the following measures related to international travel.
Actions are recommended to:
14. Encourage authorities, health care providers and community groups to provide travelers with
relevant information to protect themselves and others before, during and after travel to events
or gatherings where mpox may present a risk.
15. Advise individuals suspected or known to have mpox, or who may be a contact of a case, to
adhere to measures to avoid exposing others, including in relation to international travel.
16. Refrain from implementing travel-related health measures specific for mpox, such as entry or
exit screening, or requirements for testing or vaccination.
The Review Committee’s majority acknowledged that the worldwide spread of MPXV was also due to
inequity in access to medical countermeasures in lower resource settings, including diagnostics,
vaccines and therapeutics. Nevertheless, Members of the Review Committee expressed different views
regarding the following two proposed standing recommendations, which address clinical care and
access to countermeasures respectively. Some Members considered that these issues fall outside the
scope of IHR as per Article 2. Other Members, acknowledging that their interpretations of Article 2 are
broader than the previous view, considered the issue of equity in access to medical countermeasures
critical not only to the response to multi-country outbreak of mpox, but particularly in the African
countries where MPXV has historically been circulating. Similarly, it was argued that the provision of
clinical care has a direct impact on the clinical outcomes of mpox, consequently on the morbidity and
mortality, and an indirect effect on the reduction of international transmission. Therefore, the two
recommendations below are included for the discretion of the Director-General.
22
F. States Parties are encouraged to continue providing guidance and coordinating resources for
delivery of optimally integrated clinical care for mpox, including access to specific treatment and
supportive measures to protect health workers and caregivers as appropriate. States Parties are
encouraged to take actions to:
17. Ensure provision of optimal clinical care with infection prevention and control measures in
place for suspected and confirmed mpox in all clinical settings. Ensure training of health care
providers accordingly and provide personal protective equipment.
18. Integrate mpox detection, prevention, care and research within HIV and sexually transmitted
disease prevention and control programmes, and other health services as appropriate.
G. States Parties are encouraged to work towards ensuring equitable access to safe, effective and
quality-assured countermeasures for mpox, including through resource mobilization mechanisms.
States Parties are encouraged to take action to:
19. Strengthen provision of and access to diagnostics, genomic sequencing, vaccines, and
therapeutics for the most affected communities, including in resource-constrained settings
where mpox occurs regularly, and including for men who have sex with men and groups at risk
of heterosexual transmission, with special attention to those most marginalized within those
groups.
20. Make mpox vaccines available for primary prevention (pre-exposure) and post-exposure
