More yellow fever concern in Brazil
Four people from the state of São Paulo who visited the neighboring state of Minas Gerais have died from yellow fever. A detailed investigation is underway to try to determine exactly where these patients might have been infected. Recent outbreaks of jungle (sylvatic) yellow fever have been reported in Minas Gerais. There is concern that the virus may be transferred to the aedes mosquito that lives in urban areas, raising the possibility of a major urban outbreak of this disease.
Travellers to areas where there is a risk of exposure to yellow fever can reduce that risk by obtaining a yellow fever vaccination 10 days before travelling. In addition, travellers should take all necessary precautions to avoid mosquito bites. Travellers are reminded that many other countries require proof of yellow fever vaccination upon arrival for all travellers equal to or greater than 9-12 months of age arriving from a country where there is a risk of yellow fever.
