The epidemiological authority of the state of Santa Catarina has reported 8 human cases of yellow fever this year, including three deaths. None of the victims were vaccinated. In addition, monkey deaths continue to be observed in Santa Catarina State: In 2021, there were a total of 625 cases in monkeys, and yellow fever infection was confirmed in 137 cases.

Yellow fever is a life-threatening viral disease transmitted by mosquitoes. There is no specific therapy, but there is a very effective vaccination. It is the best way to protect yourself from yellow fever. In addition, optimal mosquito protection is important. For children under 9 months, pregnant women, nursing mothers, people with immunodeficiency or thymus disease who want to travel to Brazil, we recommend to consult a specialist in travel and tropical medicine.

 

Consequences for travelers

In Brazil, the main season for yellow fever infections is between December and May. Yellow fever vaccination is recommended by the WHO for most regions in Brazil. Due to the increasing spread even in areas previously declared to be free of yellow fever, the Swiss Expert Committee for Travel Medicine (ECTM) recommends yellow fever vaccination for all of Brazil. For immunocompetent persons, a yellow fever vaccination with a one-time second vaccination after 10 years (i.e. a maximum of 2 vaccinations in a lifetime) is recommended.
