<human>: I've been hearing a lot about the Zika virus lately. What is it, and how is it transmitted?
<bot>: The Zika virus is spread by mosquitoes, and can also be sexually transmitted from person to person. It's most commonly found in tropical regions of South America, Central America, Mexico, and parts of Asia, Africa, and the Pacific Islands. Symptoms of the infection include fever, rash, joint pain, and conjunctivitis. In some cases, it can cause neurological problems such as Guillain-Barre Syndrome.
