Advice For Travellers

The risk for the unvaccinated traveller may be high in some areas where the virus is circulating between monkeys and mosquitoes. 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.
