First Mosquito Samples to Test Positive for West Nile Virus in Suffolk County This Season
Residents and visitors are advised to take precautions
Suffolk County Health Commissioner Dr. James Tomarken announced today that five mosquito samples have tested positive for West Nile virus. The samples, all Culex pipiens-restuans, were collected on July 25, 2019 from Cold Spring Harbor (2), Northport (1), Brentwood (1), and Melville (1). These are the first mosquito samples to test positive for West Nile virus in Suffolk County this year.
In addition, two dead birds, one collected in Northport, the other collected in Nesconset, tested positive for 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. No humans or horses have tested positive for West Nile virus in Suffolk this year.
“The confirmation of West Nile virus in mosquito samples or birds indicates the presence of West Nile virus in the area,” said Dr. Tomarken. “While there is no cause for alarm, we advise residents to cooperate with us in our efforts to reduce the exposure to the virus, which can be debilitating to humans.”
According to Dr. Tomarken, most people infected with West Nile virus will experience mild or no symptoms, but some can develop severe symptoms including 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 of age or older, or those with compromised immune systems, who are most at risk, are urged to take precautions to avoid being bitten by mosquitoes.
To avoid mosquito bites, residents are advised to:
- 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.
- Download a copy of Suffolk County’s informational brochure “Get the Buzz on Mosquito Protection,” available in English and Spanish, and share it with your community.
