###Human: Is pregnant woman at high risk to acquire Zika virus? ###Assistant: Hello. Yes, Zika virus is affecting pregnancies and does have adverse effects on your baby if the mother gets exposed to it in her first trimester or either later in pregnancy. Unfortunately, no precautionary measures are available other than avoiding the exposure to it. I would suggest you to better avoid it in the first place rather than having remorse afterward. I hope it has helped you. If you require any further queries, please do not hesitate to contact me.
