Update rapid risk assessment on yellow fever in Brazil

18 Apr 2017

 

​ECDC has updated its rapid risk assessment on yellow fever in Brazil following the continuing expansion of the outbreak.

 
The Brazilian authorities have only reported yellow fever cases related to sylvatic transmission in 2016 and 2017. However, this outbreak should be carefully monitored as the establishment of an urban yellow fever cycle would have the potential to quickly affect a large number of people. EU travellers travelling to areas at risk of yellow fever in South America should be informed of the potential exposure to yellow fever virus and an individual risk benefit analysis should be conducted during pre-travel medical consultation.
 
The risk of yellow fever transmission in the EU/EEA is currently very low as it depends on the virus being introduced by viraemic travellers to an area with an established, competent and active mosquito vector population.
 
The rapid risk assessment includes options for response for EU Member States. Notably, this includes advice to EU citizens who travel to, or live in areas where there is evidence of periodic or persistent yellow fever virus transmission, especially those in outbreak-affected regions. They are advised to be aware of the risk of yellow fever in endemic areas throughout South America, including recently affected States in Brazil (Minas Gerais, Espírito Santo, Pará, Rio de Janeiro and São Paulo) and to check vaccination status and get vaccinated if necessary.
