What is West Nile Virus?

It’s one of a group of viruses spread by mosquito bites. West Nile Virus (WNV) is a flavivirus historically found in Africa, West Asia, and the Middle East. It is closely related to St. Louis encephalitis virus found in the United States. The virus can infect humans, birds, mosquitoes, horses and some other animals.
