So I'm suppose to go to Costa Rica the end of August. I was informed about the Zika virus which causes your baby to be born with a small head the brain is not fully developed if you get bitten by a mosquito with the Virus. So supposed to be a girls trip I talk to my friend about it and she said that she was already aware of the virus. So are we to pay for my airfare which is five $524 but I don't want to risk my baby's development just to go away. What your thoughts?
