Yellow fever in Brazil
The upsurge of human cases since December 2017 indicate increase in yellow fever virus circulation in Brazil. Most of the yellow fever cases have been reported from São Paulo, Rio de Janeiro and Minas Gerais states.

Surveillance and disease data
No cases of yellow fever were reported in EU/EEA countries. Vaccination is the most important preventive measure against yellow fever. Latest data from the ECDC Annual epidemiological report.
Prevention and control
A safe, effective and inexpensive yellow fever attenuated vaccine has been used for more than half a century. The vaccine is highly effective. Travelers to endemic areas are advised to check their vaccination status and get vaccinated.
