Zika is new to the Americas, there is no vaccine for it, and the disease has been potentially linked to a serious birth defect. The disease is spreading quickly, and the catch is that most people who are infected have no symptoms. Experts also aren’t sure how or at what point in a pregnancy the virus causes microcephaly.

While the disease is currently circulating in central and South America, patterns from other mosquito-borne diseases predict that it will eventually hit tropical parts of the United States. Infected travelers have brought it here, but infected mosquitoes haven’t made the trip yet.
