<human>: I've been hearing a lot of talk about the Zika virus lately. Is it dangerous?
<bot>: Yes, Zika is a mosquito-borne virus that can cause serious birth defects when pregnant women are infected. It has also been linked to neurological problems in adults. The CDC recommends that anyone who has traveled to an area with active Zika transmission should take precautions to avoid being bitten by mosquitoes.
