Zika advice for the Olympics

Due to the continuing epidemic of Zika virus infection in Brazil, the World Health Organization is advising pregnant women to avoid travelling to Rio for the upcoming Olympics since infection with this virus during pregnancy may result in serious birth defects.

Since many people have no symptoms after being infected, and since the virus may remain in semen for several weeks, the Organization is recommending that a condom should be used while having sex for at least four weeks after their return in order to avoid the risk of sexual transmission and possible infection of the fetus.

Visit our Health Library for more information on exposure to and the prevention of Zika Fever.

Advice For Travellers

Although cooler weather that is expected for the Olympics will reduce mosquito activity and the risk of being bitten by mosquitoes, travellers can minimize the risk of exposure by taking all necessary precautions to avoid mosquito bites. The risk of exposure for the general traveller in any particular location is difficult to estimate since so many infected people have no symptoms and are not recorded officially. There may be many infected people in the community.
