$81 NYC to Costa Rica, but also Zika virus

Jetblue and Delta are having a great sale right now, with $81 one-way flights to Liberia, Costa Rica. I've been there once, and it is just about everything you would imagine a tropical paradise to be,
except that the rain forest is kind of similar to a regular forest in Pennsylvania but with monkeys.

This is a great sale...but there is a travel warning due to the prevalence of the very nasty mosquito-borne Zika virus in Central and South America. It isn't known to be a big problem in Costa Rica yet, but it apparently can spread very quickly once one person gets it, as viruses do. There's no vaccine or treatment, but it usually isn't too serious. However, as far as I can tell, the long-term effects aren't known, and it is thought to cause birth defects, so you should probably not head South if you're pregnant. And lest you think this is American fearmongering, local women in Zika-affected countries are putting off pregnancy until the virus goes away.

It is a pretty good sale, though.
