On Sept. 5, 2025, the World Health Organization announced that it no longer considers the mpox outbreak in Africa to be an international health emergency.

The new form of mpox emerged in early 2024 in Congo and neighboring African countries, spread through close contact including sex. WHO declared it a global health emergency in August 2024. WHO Director-General Tedros Adhanom Ghebreyesus told reporters that an emergency panel created after the outbreak has advised that the situation is no longer an international emergency, and “I have accepted that advice.”

The international emergency declaration, the agency’s highest level of warning about threatening health issues, triggers the release of resources and enhanced public awareness campaigns, among other measures.

Mpox is a rare disease caused by infection with a virus that’s in the same family as the one that causes smallpox.

It is endemic in parts of Africa, where people have been infected through bites from rodents or small animals. Milder symptoms can include fever, chills and body aches. In more serious cases, people can develop lesions on the face, hands, chest and genitals.
