The Zika virus is spread by the same type of mosquito that carries dengue fever, yellow fever, and the chikungunya virus. The disease causes fever, rash, joint pain, and pinkeye. But most people don't have symptoms. The CDC is still investigating links between the Zika virus and the birth defect microcephaly. It advises pregnant women or women who expect to become pregnant to postpone travel to areas where the Zika virus is active.
