Advice For Travellers

The risk of exposure to this virus will vary from place to place. The risk may be high in some localities since infection with this virus usually causes a rather mild illness similar to flu, and there may be many cases in the community that do not seek medical attention and are not reported to health authorities.

Travellers can minimize the risk of exposure by taking all necessary precautions to avoid mosquito bites. Until the association between infection with this virus and the increase in cases of microcephaly (small brain) in newborns in Brazil is clarified, women who are in the first trimester of pregnancy should take extra precautions to avoid mosquito bites.
