I've been hearing a lot of talk about the Zika virus. What should I know?

The Zika virus is a mosquito-borne virus that can cause severe birth defects when pregnant women are infected. It has spread rapidly in recent years, and there have been many cases of babies being born with microcephaly due to their mothers' infection during pregnancy. The World Health Organization (WHO) has warned that the virus is now present in almost all countries in the Americas, and it's also spreading through Africa and Asia. There is currently no vaccine or treatment for the virus, but scientists are working on developing both.
