Yellow fever cases in Minas Gerais, Brazil, are growing concern

There is concern in the provincial capital city of Belo Horizonte as the number of people infected with yellow fever virus appears to have risen dramatically in just the past 7 days. The number of reported cases increased from the first detected cases in the state to 110 infected people. Forty have died. It is not clear what percentage of the patients are infected with the jungle (sylvatic) form of this infection.

The governor of the state has declared a state of emergency. For the first time ever, the disease appeared in the municipalities of Gobernador Valladares and Ladainha.

Advice For Travellers

Although the risk of exposure for the general traveller is probably low at present, the risk can increase dramatically for unvaccinated people, if the virus gains a foothold in mosquitoes in urban areas. 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.
