Yellow fever is a mosquito-borne viral infection endemic in tropical countries of Africa and South America. The majority of outbreaks previously occurred in West Africa, but more recently an increased number of cases are being reported from Central Africa. A large outbreak in Darfur resulted in 71 deaths among more than 800 suspected cases as reported by the Sudanese Ministry of Health and the WHO. In South America, YF is seen in the very rural areas of Peru and Bolivia. However, more recently, cases have been reported in urban areas including major tourist cities in Brazil. The YF vaccine is available for routine use in endemic areas, in regions with outbreaks and it is recommended prior to travel to these high-risk areas. An updated summary of the epidemiology of YF and recommendations for YF vaccine-including countries where YF vaccination is recommended for travelers - is published by the Centers for Disease Control and Prevention.
