West Nile virus is a disease transferred through the bite of an infected mosquito. Mosquitoes become infected by biting infected birds and then transmitting the virus to humans. This virus is passed onto humans through a genus of mosquitoes called Culex, which is common in Europe, the Middle East, India, parts of Asia, Africa, and has been found in North America since 1999. West Nile virus is common in Indiana mosquitoes and human infections generally occur annually.
