4 April 2017 - The WHO Secretariat determined that the following areas in the States of Bahia, Rio de Janeiro, and São Paulo should be considered at risk for yellow fever. Vaccination against yellow fever is recommended for international travellers visiting the State of Rio de Janeiro and at risk areas in the states of Bahia and São Paulo.
WHO/PAHO works with Brazilian government in response to yellow fever outbreak
31 March 2016 - WHO/PAHO has provided support to Brazil in responding to the ongoing outbreak of yellow fever. The collaboration ranges from provision of vaccines through the International Coordinating Group for Vaccine Provision (ICG), to dissemination of scientific, evidence-based recommendations. WHO/PAHO teams have been active in several areas, including mosquito control, data analysis and working with patients infected or suspected to be infected with yellow fever.
30 March 2017 - In response to the yellow fever outbreak currently on-going in Brazil some 3.5 million doses of vaccine from the emergency stockpile were deployed to the country through the International Coordinating Group (ICG) on Vaccine Provision for yellow fever. The ICG oversees a continuously replenished emergency stockpile of 6 million doses of yellow fever vaccine. The ICG includes four agencies: the World Health Organization (WHO), United Nations Children’s Fund (UNICEF,) the International Federation of Red Cross and Red Crescent Societies (IFRC), and Médicines Sans Frontières (MSF). The Government of Brazil will reimburse the cost of the 3.5 million doses sent through the yellow fever emergency stockpile financed by Gavi Alliance.
Be proactive and protect yourself from yellow fever
People living in or travelling to potentially endemic areas of yellow fever transmission should protect themselves. The yellow fever vaccine provides life-long protection against the disease. You should protect yourself from mosquito bites by wearing light-coloured, long-sleeved shirts and trousers, sleeping under a bed net day and night, using insect repellents and getting rid of stagnant water from places where mosquitoes breed.
Information products on yellow fever and vaccination are available in multiple languages including Portuguese.
Changes in the way humans live and work, and the resurgence of mosquito vectors, particularly the Aedes aegypti mosquito (which spreads Zika, dengue fever and chikungunya), have raised the global risk of yellow fever. Two large yellow fever outbreaks in Angola and Democratic Republic of the Congo are now under control but these are just warnings of bigger outbreaks to come if action is not taken.
A coalition of partners working to stop yellow fever outbreaks met in Geneva on 12 September 2016 to develop a new strategy - Eliminating Yellow fever Epidemics (EYE). This strategy aims to protect the populations most at risk, ensure a ready supply of yellow fever vaccine, build resilience in urban centres and prevent international spread.
