First Mosquito Pool with West Nile Virus Found in Nassau County

The New York State Department of Health reported today on the first isolation of West Nile virus (WNV) from a mosquito pool in Nassau County, New York.  The virus was identified in a sample of Culex pipiens mosquitos, a species which primarily bites birds.  The sample was collected July 19th in Hicksville.

To date, no humans, horses or birds have tested positive for West Nile Virus in Nassau County.

Nassau County has no plans to spray for adult mosquitoes at this time.

The continued presence of the West Nile virus in mosquitoes is not unexpected,” said Dr. David Ackman, Nassau County Commissioner of Health. “While the risk to humans is quite low, this is a good time for residents to take measures to protect themselves and their neighbors.”

The Departments of Health and Public Works will continue their mosquito control efforts by inspecting breeding sites and, when necessary, applying larvicide. Mosquito surveillance will continue at 42 trap sites located throughout the county and will be intensified in the Hicksville area. The County will continue the routine aerial applications of larvicide in the non-populated areas in the salt marshes off Jones Beach.

Because West Nile virus is present throughout New York State and beyond, and the primary carrier of WNV in Nassau County is the Culex pipiens, or “house mosquito” which flies approximately 200 feet from its breeding site, residents are urged to continue to take these precautions for safety and protection:

• Remove or empty standing water from old tires, garbage cans, pails, or any object that can hold water.
• Make sure roof gutters drain properly, and clean clogged gutters in the spring and fall.
• Keep swimming pools chlorinated and their covers free of stagnant water
• Change the water in birdbaths every two or three days.
• Install window and door screens and keep them in good repair.
• Consider wearing long sleeves, pants, socks and mosquito repellent (according to directions) when outdoors where mosquitoes are active, especially in the late afternoon and from dusk to dawn.
