This present Illness Outbreak Information on the multi-country monkeypox outbreak is an replace to the beforehand printed Disease Outbreak News of 10 June, with up to date knowledge, some additional particulars on surveillance and reporting, One Well being, gatherings, Threat communication and group engagement and Worldwide journey and factors of entry.

On this version, we’re eradicating the excellence between endemic and non-endemic international locations, reporting on international locations collectively the place potential, to replicate the unified response that’s wanted.

Outbreak at a look

Since 1 January 2022, circumstances of monkeypox have been reported to WHO from 42 Member States throughout 5 WHO areas (the Areas of the Americas, Africa, Europe, Jap Mediterranean, and Western Pacific). As of 15 June, a complete of 2103 laboratory confirmed circumstances and one possible case, together with one demise, have been reported to WHO. The outbreak of monkeypox continues to primarily have an effect on males who’ve intercourse with males who’ve reported latest intercourse with new or a number of companions.

Whereas epidemiological investigations are ongoing, most reported circumstances within the latest outbreak have offered by way of sexual well being or different well being companies in main or secondary well being care amenities, with a historical past of journey primarily to international locations in Europe, and North America or different international locations somewhat than to international locations the place the virus was not traditionally identified to be current, and more and more, latest journey domestically or no journey in any respect.

Affirmation of 1 case of monkeypox, in a rustic, is taken into account an outbreak. The surprising look of monkeypox in a number of areas within the preliminary absence of epidemiological hyperlinks to areas which have traditionally reported monkeypox, means that there could have been undetected transmission for a while.

WHO assesses the danger on the international degree as average contemplating that is the primary time that many monkeypox circumstances and clusters are reported concurrently in lots of international locations in broadly disparate WHO geographical areas, balanced in opposition to the truth that mortality has remained low within the present outbreak.

Description of the outbreak

Between 1 January to fifteen June 2022, a cumulative whole of 2103 laboratory confirmed circumstances, one possible case, and one demise have been reported to WHO from 42 international locations in 5 WHO Areas. The vast majority of circumstances (98%) have been reported since Could 2022 (Determine 1).

Word: the information for the present epi week are incomplete and needs to be interpreted cautiously.

The bulk (84%) of confirmed circumstances (n=1773) are from the WHO European Area. Confirmed circumstances have additionally been reported from the African Area (n=64; 3%), the Area of the Americas (n=245; 12%), Jap Mediterranean Area (n=14; <1%) and Western Pacific Area (n=7; <1%). Of circumstances reported (468 out 2103 confirmed circumstances) from 14 international locations for which demographic data and private traits can be found, 99% are reported in males aged 0 to 65 years (Interquartile vary: 32 to 43 years; median age 37 years), of which most self-identify as males who’ve intercourse with different males.

Thus far, the medical presentation of monkeypox circumstances related to this outbreak has been variable. Many circumstances on this outbreak usually are not presenting with the classically described medical image for                monkeypox (fever, swollen lymph nodes, adopted by a centrifugal evolving rash). Atypical options described embody: presentation of just a few and even only a single lesion; lesions that start within the genital or perineal/perianal space and don’t unfold additional; lesions showing at totally different (asynchronous) phases of growth; and the looks of lesions earlier than the onset of fever, malaise and different constitutional signs. The modes of transmission throughout sexual contact stay unknown; whereas it’s identified that shut bodily and intimate skin-to-skin or face-to-face contact can result in transmission (by way of direct contact with infectious pores and skin or lesions), it’s not clear what position sexual bodily fluids, comparable to semen and vaginal fluids, play within the transmission of monkeypox.

At present, the general public well being danger on the international degree is assessed as average contemplating that is the primary time that monkeypox circumstances and clusters are reported concurrently in lots of international locations in broadly disparate WHO geographical areas, balanced in opposition to the truth that mortality has remained low within the present outbreak.

In apparently newly affected international locations, circumstances have primarily, however not solely, been confirmed amongst males who self-identify as males who’ve intercourse with males, collaborating in prolonged sexual networks. Individual to individual transmission is ongoing, nonetheless primarily occurring in a single demographic and social group. It’s possible that the precise variety of circumstances stays an underestimate. This may occasionally partly be as a result of lack of early medical recognition of an infectious illness beforehand thought to happen principally in West and Central Africa, a non-severe medical presentation for many circumstances, restricted surveillance, and an absence of broadly obtainable diagnostics. Whereas efforts are underway to deal with these gaps, it is very important stay vigilant for monkeypox in all inhabitants teams to stop onward transmission.

At current, transmission in apparently newly affected international locations is primarily linked to latest sexual contacts. There’s the excessive chance that additional circumstances will probably be discovered with out recognized chains of transmission, together with probably in different inhabitants teams. Given the variety of international locations throughout a number of WHO areas reporting circumstances of monkeypox, it’s extremely possible that different international locations will establish circumstances and there will probably be additional unfold of the virus. Human-to-human transmission happens by way of shut or direct bodily contact (face-to-face, skin-to-skin, mouth-to-mouth, mouth-to-skin) with infectious lesions or mucocutaneous ulcers together with throughout sexual exercise, respiratory droplets (and presumably short-range aerosols), or contact with contaminated supplies (e.g., linens, bedding, electronics, clothes, intercourse toys).

The present danger for most of the people stays low. There’s a danger to well being staff if they’re involved with a case whereas not carrying acceptable private protecting tools (PPE) to stop transmission; although not but reported on this present outbreak, the danger of well being care-associated infections has been documented previously. Ought to monkeypox start to unfold extra broadly to and inside extra susceptible teams, there’s the potential for better well being ­­­impression as the danger of extreme illness and mortality is acknowledged to be greater in immunocompromised people, together with individuals with poorly managed HIV an infection. Whereas an infection with monkeypox throughout being pregnant is just not absolutely understood, restricted knowledge recommend that an infection could result in hostile outcomes for the foetus or new child toddler and for the mom.

Thus far, all circumstances recognized in newly affected international locations whose samples had been confirmed by PCR have been recognized as being contaminated with the West African clade. There are two identified clades of monkeypox virus, one first recognized in West Africa (WA) and one within the Congo Basin (CB) area. The WA clade has previously been related to an total decrease case fatality ratio (CFR) of <1% whereas the CB clade seems to extra often trigger extreme illness with a CFR beforehand reported of as much as about 10%; each estimates are based mostly on infections amongst a usually youthful inhabitants within the African setting. Within the interval following the eradication of smallpox, extra folks had been resistant to orthopoxviruses by way of publicity to smallpox or receipt of smallpox vaccine. Subsequently, initially most early circumstances of human monkeypox had been amongst kids who had been susceptible and due to this fact vulnerable to extra extreme illness.

Vaccination in opposition to smallpox was proven previously to be cross-protective in opposition to monkeypox. In the present day, any persevering with immunity from prior smallpox vaccination would typically solely be current in individuals over the age of 42 to 50 years or older, relying on the nation, since smallpox vaccination programmes ended worldwide in 1980 after the eradication of smallpox. Safety for many who had been vaccinated could have waned over time. The unique (first era) smallpox vaccines from the eradication programme are now not obtainable to most of the people.

Smallpox and monkeypox vaccines, the place obtainable, are being deployed in just a few international locations to handle shut contacts. Second- and third-generation smallpox vaccines have been developed to have an improved security profile and one has been permitted for prevention of monkeypox. This vaccine relies on a pressure of vaccinia virus (identified generically as modified vaccinia Ankara Bavarian Nordic pressure, or MVA-BN). This vaccine has been permitted for prevention of monkeypox in Canada and america of America. Within the European Union, this vaccine has been permitted for prevention of smallpox beneath distinctive circumstances. An antiviral agent, tecovirimat, has been permitted by the European Medicines Company, Well being Canada, and america Meals and Drug Administration for the remedy of smallpox. It is usually permitted within the European Union for remedy of monkeypox. WHO has convened specialists to assessment the newest knowledge on smallpox and monkeypox vaccines, and to offer steerage on how and in what circumstances they can be utilized.


The recommendation offered hereafter by the WHO on actions required to reply to the multi-country monkeypox outbreak, relies on its technical work, and knowledgeable by consultations with the next current WHO advisory our bodies: the Strategic and Technical Advisory Group on Infectious Hazards (STAG-IH); the ad-hoc Strategic Advisory Group of Specialists on Immunization (SAGE) working group on smallpox and monkeypox vaccines; the Emergencies Social Science Technical Working Group; the Advisory Committee on Variola Virus Analysis; WHO Analysis & Improvement (R&D) Blueprint session: Monkeypox analysis; the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO); in addition to by the end result of ad-hoc conferences of specialists.

All international locations needs to be on the alert for indicators associated to sufferers presenting with a rash that progresses in sequential phases – macules, papules, vesicles, pustules, scabs, on the similar stage of growth over all affected areas of the physique – which may be related to fever, enlarged lymph nodes, again ache, and muscle aches. Throughout this present outbreak, many people are presenting with atypical signs, which features a localized rash which will current as little as one lesion.  The looks of lesions could also be asynchronous and individuals could have primarily or solely peri-genital and/or peri-anal distribution related to native, painful swollen lymph nodes. Some sufferers might also current with sexually transmitted infections and needs to be examined and handled appropriately. These people could current to numerous group and well being care settings together with however not restricted to main and secondary care, fever clinics, sexual well being companies, infectious illness models, obstetrics and gynaecology, emergency departments and dermatology clinics.

Growing consciousness amongst probably affected communities, in addition to well being care suppliers and laboratory staff, is important for figuring out and stopping additional circumstances and efficient administration of the present outbreak.

Any particular person assembly the definition for a suspected case needs to be supplied testing. The choice to check needs to be based mostly on each medical and epidemiological components, linked to an evaluation of the chance of an infection. As a result of vary of situations that trigger pores and skin rashes and since medical presentation could extra typically be atypical on this outbreak, it may be difficult to distinguish monkeypox solely based mostly on the medical presentation.

Caring for sufferers with suspected or confirmed monkeypox requires early recognition by way of screening tailored to native settings, immediate isolation and fast implementation of acceptable IPC measures (customary and transmission-based precautions, together with the addition of respirator use for well being staff caring for sufferers with suspected/confirmed monkeypox, and an emphasis on protected dealing with of linen and administration of the surroundings), bodily examination of affected person, testing to verify prognosis, symptomatic administration of sufferers with delicate or uncomplicated monkeypox and monitoring for and remedy of issues and life-threatening situations comparable to development of pores and skin lesions, secondary bacterial an infection of pores and skin lesions, ocular lesions, and barely, extreme dehydration, extreme pneumonia or sepsis. Sufferers with much less extreme monkeypox who isolate at residence require cautious evaluation of the flexibility to soundly isolate and preserve required IPC precautions of their residence to stop transmission to different family and group members.

Precautions (isolation) ought to stay in place till lesions have crusted, scabs have fallen off and a recent layer of pores and skin has fashioned beneath.

Info ought to attain those that want it most throughout upcoming small and enormous gatherings, significantly amongst social and sexual networks the place there could also be shut, frequent or extended bodily or sexual contact, significantly if this includes a couple of associate. All efforts needs to be made to keep away from pointless stigmatization of people and communities probably affected by monkeypox.

WHO is intently monitoring the scenario and supporting worldwide coordination working with Member States and companions.

For associated WHO paperwork, please see the Info part under. Key updates from these paperwork in addition to highlights from paperwork beneath growth are offered under for ease of reference.

Surveillance and reporting 

As per IHR (2005) Article 6, a minimal knowledge set (formatted as a case report type) for reporting beneath IHR has been developed and shared with Member States. The info will probably be compiled and shared publicly in combination type frequently by way of WHO data merchandise. A separate in-depth Case Investigation and Contact Tracing Type (CIF) for Member States has been additionally shared with Member States. This way can be utilized for investigation of publicity dangers and transmission dynamics of circumstances and secondary an infection danger in contacts. WHO is working to establish Member States who could also be fascinated about sharing these detailed knowledge, or analyses, to tell the worldwide understanding of the present outbreak. A protocol to help implementation of the CIF is being additionally finalized.

WHO has additionally carried out the Case Reporting Form (CRF) and CIF within the Go.Data platform to facilitate native seize, evaluation, and/or sharing of the related knowledge. Evaluation of transmission chains and community visualization have been utilized in previous outbreaks to establish clusters, perceive patterns of publicity, and quantify viral transmission throughout totally different settings. Within the context of the present monkeypox outbreak, understanding these patterns of transmission will probably be essential not solely find which management measures are efficient, however will permit for the characterization of the extent of respiratory transmission and figuring out if a number of introductions (human or zoonotic) have occurred. Thus far, restricted instruments can be found for international locations to have the ability to graph these chains of transmission and establish clusters or contexts of transmission in actual time. This presents a chance for Go.Knowledge for use by Member States, companions, and establishments to boost outbreak response actions, primarily within the era, visualization, and evaluation of their chains of transmission. By means of its “visualization” function, Go. Knowledge will permit international locations to visualise, in real-time, chains of transmission which can facilitate the monitoring of illness development in addition to the identification of potential new circumstances which can be missed by way of undetected circulation of the virus or new circulating clades. The Go.Knowledge monkeypox outbreak template and related metadata description may be obtained upon request by emailing [email protected], and technical help for implementation is obtainable from WHO.

Laboratory testing and pattern administration

Particulars may be present in Laboratory testing for the monkeypox virus: Interim guidance (23 May 2022)

Threat communication and group engagement

Speaking monkeypox associated dangers and interesting at-risk and affected communities, group leaders, civil society organizations, and well being care suppliers, together with these at sexual well being clinics, on prevention, detection and care, is important for stopping additional secondary circumstances and efficient administration of the present outbreak. Offering public well being recommendation on how the illness transmits, its signs and preventive measures and concentrating on group engagement to the inhabitants teams who’re most in danger, is essential to attenuate unfold. Communication have to be direct, express and interesting for the meant viewers.

Anybody who has direct contact, (e.g., face-to-face, skin-to-skin, mouth-to-mouth, mouth-to-skin) together with however not restricted to sexual contact, with an contaminated particular person can get monkeypox. Steps for self-protection embody avoiding sexual contact with somebody with a localized anogenital rash or pores and skin lesions and limiting the variety of intercourse companions; avoiding shut contact with somebody who has signs in step with potential monkeypox an infection and keep away from sharing of non-public gadgets (e.g. consuming utensils, clothes, digital gadgets, bedding); maintaining arms clear with water and cleaning soap or alcohol-based gels; and sustaining respiratory etiquette.

If an individual develops signs comparable to a rash with blisters on face, arms, ft, eyes, mouth, and/or genitals and peri-anal areas; fever; swollen lymph nodes; complications; muscle aches; and fatigue they need to contact their well being care supplier and get examined for monkeypox. If somebody is suspected or confirmed as having monkeypox, they need to isolate, be examined, endure medical analysis to evaluate for issues, keep away from skin-to-skin and face-to-face contact with others and keep away from intercourse, together with receptive and insertive oral, anal, or vaginal sexual activity, till all lesions have crusted, the scabs have fallen off and a recent layer of pores and skin has fashioned beneath. Throughout this era, circumstances can get supportive remedy to ease monkeypox signs. Anybody caring for an individual sick with monkeypox ought to use acceptable private protecting measures as talked about above. As a precaution, WHO suggests the usage of condoms persistently throughout sexual exercise (receptive and insertive oral/anal/vaginal) for 12 weeks publish restoration to scale back the potential transmission of monkeypox for which the danger is as but not identified.

Residents and travellers to international locations which have lengthy skilled monkeypox ought to keep away from contact with sick mammals comparable to rodents, marsupials, non-human primates (useless or alive) that would harbour monkeypox virus and will chorus from consuming or dealing with wild recreation (bush meat). In a earlier outbreak in 2003 in america of America, homeowners of pet prairie canines had been contaminated by way of contact with their contaminated pets. Subsequently, individuals with monkeypox in any setting needs to be conscious of the theoretical danger of exposing animals, for instance those that could also be stored as pets within the family.

WHO is regularly updating its content material by way of Monkeypox Q&A, public communication platforms and different supplies. Please check with the WHO Steerage and Public Well being Suggestions part under.


Gatherings and occasions the place bodily contact, together with intercourse, could also be concerned could signify a conducive surroundings for the transmission of monkeypox virus in the event that they entail shut, extended or frequent interactions amongst folks, which in flip may expose attendees to contact with lesions, physique fluids, respiratory droplets and contaminated supplies.

Deliberate gatherings in areas the place monkeypox circumstances have been detected may be safely maintained with just a few precautions and sharing of knowledge as required. Moreover, such occasions can be utilized as alternatives to conduct outreach with public well being data for particular inhabitants teams. It is very important talk early, typically, persistently by way of identified and trusted communication channels and in language and terminology utilized by the affected populations. Public well being authorities and occasion managers ought to work collectively to make sure focused data reaches event-goers earlier than, throughout and after the occasion. Working intently with community-based and civil society organisations which have direct and trusted relationship with affected populations is extremely advisable.

The next precautionary measures may be thought of to scale back danger of monkeypox transmission related to such occasions:

  • Occasion organizers ought to pay attention to the epidemiology of monkeypox within the host space, its modes of transmission and prevention, and what motion needs to be taken if an individual develops indicators and signs appropriate with monkeypox, together with the place acceptable care may be sought. This data needs to be shared with potential attendees and all these concerned within the occasion planning and supply.
  • Gatherings needs to be used as alternatives for data outreach and group engagement; consideration must also be devoted to the social context by which the occasion takes place, with a deal with particular person danger behaviours related to facet occasions and unplanned congregations (i.e.. gatherings in bars and pubs, home events, personal areas, and so forth.).
  • Folks with indicators and signs in step with monkeypox ought to chorus from shut contact with every other particular person and will keep away from attending gatherings. They need to observe recommendation issued by related well being authorities.
  • Though monkeypox and COVID-19 unfold between folks in another way, a few of the COVID-19 measures utilized throughout social gatherings comparable to maintaining a bodily distance and working towards common handwashing are additionally efficient in opposition to the transmission of monkeypox virus; as such, they need to be continued; skin-to-skin and face-to-face contact needs to be discouraged.
  • Shut contact with somebody who has indicators or signs in step with monkeypox needs to be prevented, together with not having intimate or sexual contact.
  • Attendance lists for contributors in gatherings may be launched, if relevant, to facilitate contact tracing within the occasion {that a} monkeypox case is recognized.
  • Workers chargeable for coping with attendees who fall in poor health on the occasion needs to be supplied with data on easy methods to handle folks with indicators and signs in step with monkeypox.
  • Attendees ought to all the time be reminded to use individual-level duty to their choices and actions, with the goal of preserving their well being, that of the folks they work together with, and finally that of their group. That is particularly necessary for spontaneous or unplanned gatherings.

As it’s customary apply for mass gatherings, and much more so throughout the COVID-19 pandemic, authorities and occasion organizers are invited to use the WHO advisable risk-based strategy to decision-making, and tailor it to the massive or small social occasions into account. Within the context of the present outbreak, monkeypox-associated dangers needs to be thought of and factored in.

One Well being

Varied wild mammals have been recognized as vulnerable to monkeypox virus in areas which have lengthy skilled monkeypox. These embody rope squirrels, tree squirrels, Gambian pouched rats, dormice, non-human primates, amongst others. Some species could have asymptomatic an infection. Different species, comparable to monkeys and nice apes, present pores and skin rashes typical of these present in people. Up to now, there is no such thing as a documented proof of home animals or livestock being affected by monkeypox virus. There’s additionally no documented proof of human-to-animal transmission of monkeypox. Nonetheless, there stays a hypothetical danger of human-to-animal transmission; as such acceptable measures comparable to bodily distancing of individuals with monkeypox from home pets, correct waste administration to stop the illness from being transmitted from contaminated people to vulnerable animals at residence (together with pets), in zoos and wildlife reserves, and to peri-domestic animals, particularly rodents.

Worldwide journey and factors of entry

Based mostly on obtainable data presently, WHO doesn’t suggest that Member States undertake any  measures that intrude with worldwide visitors for both incoming or outgoing travellers.

Any particular person feeling unwell, together with fever with rash-like sickness, or being thought of a suspected or confirmed case of monkeypox by jurisdictional well being authorities, ought to keep away from endeavor any journey, together with worldwide or native journey, till  now not thought of a public well being danger by a well being care supplier or public well being unit. Any particular person who has developed a rash-like sickness throughout journey or upon return ought to instantly report back to a well being skilled, offering details about all latest journey, immunization historical past together with whether or not they have acquired smallpox vaccine or different vaccines (e.g. measles-mumps-rubella, varicella zoster vaccine, to help making a prognosis), and data on shut contacts as per WHO interim steerage on surveillance, case investigation and phone tracing for monkeypox (please check with the WHO Steerage and Public Well being Suggestions part under). People who’ve been recognized as contacts of monkeypox circumstances and, due to this fact, are topic to well being monitoring, ought to keep away from endeavor any journey, together with worldwide, till completion of their well being monitoring interval.

Public well being officers ought to work with journey operators and public well being counterparts in different places to contact passengers and others who could have had shut contact with an infectious particular person whereas travelling. Well being promotion and danger communication supplies needs to be obtainable at factors of entry, together with data on easy methods to establish indicators and signs in step with monkeypox; on the precautionary measures advisable to stop its unfold; and on easy methods to search medical care on the place of vacation spot when wanted.

WHO urges all Member States, well being authorities in any respect ranges, clinicians, well being and social sector companions, and tutorial, analysis and business companions to reply shortly to include native unfold and, by extension, the multi-country outbreak of monkeypox. Fast motion have to be taken earlier than the virus may be allowed to ascertain itself as a human pathogen with environment friendly person-to-person transmission in areas in any beforehand affected or newly affected areas.
