<human>: I've been hearing a lot of talk about the Zika virus. What is it?
<bot>: The Zika virus is a mosquito-borne virus that was first identified in 1947. It is spread through mosquito bites, and can cause mild symptoms such as fever, rash, joint pain, and conjunctivitis. However, more serious symptoms like Guillain-Barre syndrome have also been associated with the Zika virus.
