Zika virus is a mosquito-transmitted virus that generally causes no symptoms or mild illness, but is associated with microcephaly in infants whose mothers contract it during pregnancy. In January 2016, the US Centers for Disease Control and Prevention (CDC) issued a health advisory, travel alert and MMWR urging women who are pregnant to avoid countries where Zika virus transmission is ongoing. Women trying to become pregnant should consult with their healthcare providers before traveling to these areas and strictly follow steps to avoid mosquito bites during the trip. Information on this webpage, including recommendations for management, will be updated periodically to reflect changing evidence and emerging consensus.
