The Zika virus has a possible link to birth defects, specifically, microcephaly, when pregnant women are infected. Microcephaly is a rare condition in which babies are born with very small brains, blindness and deafness. This virus is spread rapidly by mosquito bites. We don’t have a vaccine or treatment for it. Luckily, though, for those living in colder areas, the type of mosquito that spreads the virus prefers warm and humid environments like Africa, Asia and Central America. Dr. Kirtly Jones recaps what we know and don’t know about the Zika virus, including possible symptoms and your chances of getting it.
