Five Mosquito Samples Test Positive for West Nile Virus

High seasonal counts prompt health officials to advise residents to be vigilant

Suffolk County Health Commissioner Dr. Gregson Pigott announced today that five mosquito samples have tested positive for West Nile virus. The samples were: three Culex pipiens-restuans collected September 24-26, from Aquebogue (1), Lindenhurst (1) and Davis Park Fire Island (1). One Culex Salinarius was collected 9/24 from The Pines Fire Island and one Culiseta melanura was collected September 27 from Manorville.

To date this season, 234 mosquito samples and five birds have tested positive for West Nile virus. One mosquito sample has tested positive for Eastern equine encephalitis (EEE) virus. To date this year, 19 people have been confirmed to have been infected with West Nile virus.

West Nile virus, first detected in birds and mosquito samples in Suffolk County in 1999 and again each year thereafter, is transmitted to humans by the bite of an infected mosquito. The first human case of West Nile virus was confirmed in 2001. Since then, nearly 150 individuals have been confirmed to have contracted West Nile virus, and nine deaths were attributed to the virus. 

“If you are heading outdoors for a walk or to do yard work, continue to take precautions to avoid being bitten,” said Dr. Pigott. “It’s also a good time to cover any holes that may have collected water and clean and repair gutters and screens.”

Severe symptoms of West Nile virus include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness, and paralysis. The symptoms may last several weeks, and neurological effects may be permanent.

Individuals, especially those 50 years or older or those with compromised immune systems, are urged to take precautions to avoid being bitten by mosquitoes. 

 Dr. Pigott offers the following tips to avoid mosquito bites:

• Minimize outdoor activities between dusk and dawn.
• Wear shoes and socks, long pants, and long-sleeved shirts when mosquitoes are active.
• Use mosquito repellent, following label directions carefully.
• Make sure all windows and doors have screens, and that all screens are in good repair.
• Keep mosquitoes from laying eggs inside and outside of your home. Once a week, empty and scrub, turn over, cover, or throw out containers that hold water, such as vases, pet water bowls, flowerpot saucers, discarded tires, buckets, pool covers, birdbaths, trash cans and rain barrels.
