Brazil Reports First Mpox Death in 2026
Brazil has recorded its first mpox-related death in 2026, but public health officials are not classifying the current surge in cases as an outbreak, according to the Fiocruz Institute.


Brazil has recorded its first mpox-related death in 2026, according to a report published by the Fiocruz Institute, which is affiliated with the health ministry. The death occurred in Rio de Janeiro, where positive cases between September and November doubled compared to those recorded during the rest of the year (source ID: 1). [1]
The government has taken steps to address the situation by enhancing surveillance measures and purchasing 25,000 new doses of an mpox vaccine. However, officials are not currently treating the rise in cases as an outbreak because the number remains "significantly lower than the historic peak experienced in 2022," according to Fiocruz (source ID: 1).

Mpox, which is caused by a virus from the same family as the smallpox virus, causes fever, muscle aches, and large boil-like skin lesions, and can be deadly. It can be transmitted to humans by animals but can also be passed between people through close physical contact (source ID: 1). [1]

This spike in infections has prompted increased surveillance measures by the government, although officials are not classifying the situation as an outbreak (source ID 1). [1]
