Advice to travellers

  • There is a widespread risk of yellow fever in Brazil, including São Paulo State and São Paulo City.
  • Yellow fever risk areas in Brazil are shown here.
  • A traveller's risk of yellow fever is determined by their general risk assessment e.g. country visited, length of stay, city or rural, activities etc.
  • Mosquito bite avoidance rules should be adhered to at all times - the mosquito that spreads yellow fever bites predominantly during the day.
  • The World Health Organisation recommends yellow fever vaccine for travellers to areas at risk of yellow fever (including all of São Paulo State and São Paulo City) unless contraindicated.
