What is Zika virus?

Zika virus is transmitted primarily by female mosquitoes and was first identified in a rhesus monkey in Uganda near the Zika Forest. The virus is a flavivirus which causes zika fever. In general, it causes mild conditions for which there is no treatment. The disease often goes away on its own. However, there is also evidence that infection can have serious consequences, especially for a fetus. In fact, microcephaly can be developed. Too small a skull size can have huge consequences for subsequent development. Spread of the Zika virus has already occurred in Africa, Asia, Europe and South and North America.
