Sudan has detected the country's first case of the monkeypox virus in the Darfur region.
The Health Ministry said late Sunday that the 16-year-old student's case was discovered last week in West Darfur province.
The ministry said there were at least 38 suspected cases of monkeypox and all tested negative to the virus but one in West Darfur.
It said health authorities were working to determine the student's contacts to limit the spread of the virus.
An outbreak of monkeypox could be devastating for Sudan, which suffered from decades of conflict in Darfur and other parts of the country, and international isolation.
The virus originates in primates and other wild animals and causes fever, body aches, chills and fatigue in most patients. People with severe cases can develop a rash and lesions on the face, hands and other parts of the body.
The smallpox-related disease was commonly found in parts of central and west Africa, before spreading to different parts of the world.
The World Health Organization last month declared monkeypox a global emergency, to ensure that the world takes the current outbreaks seriously.
