West Nile fever: Mosquito-borne infectious virus.

West Nile fever: In the early summer of 1999, cases of encephalitis (inflammation of the brain) and death began to appear in New York City. Researchers later identified West Nile virus as the cause. Prior to that time, health care experts had never seen cases of illness caused by this virus in the United States. The virus is common in Africa, West Asia, and the Middle East. Mosquitoes become infected when they feed on infected birds, which may circulate the virus in their blood for a few days. Infected mosquitoes can then transmit West Nile virus to humans and animals while biting to take blood. Every summer since it first appeared, West Nile virus has been found in a continuously increasing number of states. 1
