The Centers for Disease Control and Prevention said Friday that it is also investigating 10 additional reports of pregnant travelers with Zika.
The Zika virus — spread mainly by mosquito bites — is epidemic in Latin America and the Caribbean. The virus causes mild illness or no symptoms in most people. But in Brazil, officials are investigating a possible link to babies born with brain defects and abnormally small heads.
