​Yellow fever is a potentially fatal viral disease that is transmitted by mosquitoes in parts of South America and Africa. Yellow fever vaccination is required for travellers to these parts of the world.

Outbreak of yellow fever in Brazil - update

There is a large, ongoing outbreak of yellow fever in multiple states of Brazil, including near large urban areas and popular tourist destinations.

Since January 2018, 10 travel-related cases of yellow fever, including four deaths, have been reported in international travellers returning from Brazil. None of the 10 travellers had received yellow fever vaccination [*​].

Travellers to Brazil and other yellow fever risk areas in South America should protect themselves from yellow fever by:

  • getting the yellow fever vaccine at least 10 days before travel (only required if you have not had the vaccine before)
  • taking measures to prevent mosquito bites indoors and outdoors, especially between sunrise and sunset when mosquito vectors are most active. This also applies to places such as large recreational areas and parks, botanical gardens and nature reserves.
