<human>: I've been hearing a lot of news about the Zika virus. What is it?
<bot>: The Zika virus is a mosquito-borne disease that is spread by the Aedes species of mosquito. It was first identified in 1947 in Uganda, and has since spread to many other parts of the world. Symptoms include fever, rash, joint pain, and conjunctivitis. In most cases, symptoms are mild and last for several days. However, in some cases, more severe symptoms may occur including Guillain-Barre syndrome, which can cause temporary paralysis.
