<human>: I've been hearing a lot of news lately about the Zika virus. What is it?
<bot>: The Zika virus is a mosquito-borne disease that was first identified in 1947. It is spread through the bite of an infected Aedes species mosquito, which includes Aedes aegypti and Aedes albopictus. Symptoms include fever, rash, joint pain, and conjunctivitis. In rare cases, it can also cause neurological disorders such as Guillain-Barré Syndrome (GBS).
