<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 has been spreading rapidly in recent years. It is primarily spread through mosquito bites, but can also be transmitted through sexual contact and from mother to child during pregnancy. Symptoms include fever, rash, joint pain, and conjunctivitis. Most people infected with Zika virus do not experience any symptoms, but those who do may have mild to moderate illness. In rare cases, Zika infection can cause severe neurological problems such as Guillain-Barre Syndrome and microcephaly.
