President Obama Calls for Urgent Action, More Research on Zika Virus

President Obama is calling for urgent action and research into the Zika virus, which is now active across much of Latin America and the Caribbean.

Zika is a mosquito-borne illness that is particularly dangerous for pregnant women, as it can cause serious birth defects in babies, including a condition called microcephaly, in which babies are born with small heads and under-developed brains.
