Mpox (monkeypox) is a viral illness caused by the monkeypox virus, a species of the genus Orthopoxvirus. Common symptoms of mpox are a skin rash or mucosal lesions which can last 2-4 weeks accompanied by fever, headache, muscle aches, and low energy.
- Mpox can be transmitted to humans through physical contact with someone who is infectious, with contaminated materials, or with infected animals, according to the World Health Organisation (WHO).
- Mpox can be prevented by avoiding physical contact with someone who has mpox. Vaccination can help prevent infection for people at risk.
- The monkeypox virus was discovered in Denmark (1958) in monkeys kept for research and the first reported human case of mpox was a nine-month-old boy in the Democratic Republic of the Congo (DRC, 1970).
- Following eradication of smallpox in 1980 and the end of smallpox vaccination worldwide, mpox steadily emerged in central, east and west Africa.
- A global outbreak occurred in 2022-2023. The natural reservoir of the virus is unknown – various small mammals such as squirrels and monkeys are susceptible.
