Epidemiological Update Yellow fever in the Americas Region -19 September 2024

Between epidemiological week (EW) 1 and EW 35 of 2024, 38 confirmed cases of yellow fever have been reported in the Americas Region, including 19 deaths. This represents five cases (three in the Plurinational State of Bolivia and two in Peru) and two deaths (in Peru) since the last Pan American Health Organization/World Health Organization (PAHO/WHO) epidemiological update published on 29 July 2024. In the Americas Region, the risk of yellow fever outbreaks is high. Although immunization is one of the most successful public health interventions to prevent this disease, most of the cases reported during 2024 do not have a history of yellow fever vaccination. PAHO/WHO encourages Member States with yellow fever risk areas to continue their efforts to strengthen surveillance and vaccination in endemic areas.
