ECDC has published Epidemiological update: Yellow fever outbreak in Brazil. Excerpt from the assessment:
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.
In Brazil, authorities have reported only sylvatic cases 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. Therefore, EU/EEA Member States should consider a range of options for response.
EU/EEA citizens who travel to, or live in, areas where there is evidence of yellow fever virus transmission, particularly in the states of Brazil reporting confirmed local transmission, should consider the risk of yellow fever, check their vaccination status and get medical advice about getting vaccinated against yellow fever.
ECDC monitors closely this event in collaboration with WHO. ECDC has published a rapid risk assessment on 26 January 2017. ECDC has also published an epidemiological update and a map for travel advice.
