What precautions is the National Park Service taking to prevent an outbreak of West Nile Encephalitis in its park units in 2000?
All National Park Service areas are working in cooperation with their federal and local mosquito management and health agencies. At Fire Island National Seashore, the National Park Service, in cooperation with the Centers for Disease Control, Suffolk County Vector Control, and New York State and Suffolk County health departments, is carrying out active site specific monitoring and surveillance programs at Fire Island. The surveillance activities will make possible early detection of the virus if it returns in 2000. Samples of live mosquitoes are routinely checked at state laboratories for the presence of West Nile Virus. Positive mosquito samples will be used to trigger activities designed to decrease mosquito populations and the habitat in which they multiply. This may include pesticide spraying.
