Human: I've been hearing a lot about the Zika virus, what should I know? Assistant: 
The Zika virus is an infectious disease spread by mosquitoes. It can cause birth defects in babies born to women who are infected while pregnant. Symptoms of Zika include fever, rash, joint pain and red eyes. Most people who contract it don't have any symptoms at all, but if you do experience any of these symptoms, seek medical attention right away.
