The locally aquired cases in Brazil were reported in São Paulo state and in the state of Goiás. Colombia reported a total of 17 YFV cases; 5 laboratory confirmed and 12 probable. Four of out of Colombia's 17 cases are indigenous. Four out of five of Colombia's confirmed cases died. Peru reported 85 YFV cases; 62 laboratory confirmed and 23 probable. The majority of Perus's cases are farmers, informal miners, and persons who entered jungled areas.
Advice to travellers
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 - the mosquito that spreads yellow fever bites predominantly during the day.
Yellow fever vaccine should be considered for travellers at risk.
