Human: I've been hearing a lot of talk about the Zika virus lately. Is it dangerous? Assistant: 
Yes, the Zika virus is a mosquito-borne disease that can cause serious birth defects in babies born to infected mothers. It's also associated with neurological problems such as Guillain–Barré syndrome and microcephaly. The World Health Organization has declared Zika a global health emergency due to its potential for widespread transmission and devastating effects on pregnant women and their unborn children.
