West Nile Virus: Entrenched in U.S.

June 15, 2010

An infectious disease spread to humans by mosquitoes that have bitten infected birds, West Nile virus historically was seen only in Africa, Europe and Asia before it was first detected in the United States in 1999. Though the majority of those infected show no symptoms, the disease can be deadly, particularly in the elderly. If West Nile virus enters the brain, it can cause encephalitis or meningitis. The major way to prevent infection is to avoid mosquitoes and to reduce mosquitoes in populated areas. Updated June 2010
