The CDC says the Zika virus is scarier than they initially thought. New findings show that the virus is linked to pregnancy complications like prematurity and blindness, in addition to microcephaly. A disease that results in cognitive deficits, seizures, hearing loss and more. The baby is at risk throughout the entire pregnancy, not just the first trimester. So far, the 346 confirmed cases of Zika in the U.S. have been travel-related. But the mosquito that carries the virus is present in 30 U.S. states, and in at least one case, the disease was transmitted through sexual contact. The earliest the CDC expects to have a vaccine is 2018.
