People living in or travelling to potentially endemic areas of yellow fever transmission should protect themselves. The yellow fever vaccine provides lifelong protection against the disease. You should protect yourself from mosquito bites by wearing light-coloured, long-sleeved shirts and trousers, sleeping under a bed net day and night, using insect repellents and getting rid of stagnant water from places where mosquitoes breed.

Information products on yellow fever and vaccination are available in multiple languages including Portuguese.
