Others have been found in Oakdale, according to Suffolk County Department of Health Services Commissioner James Tomarken.
The samples, all Culex pipiens-restuans, were collected on Oct. 2 and Oct. 3rd from the two locations.
To date , 177 mosquito samples and ten birds have tested positive for West Nile virus. One human case was reported to have tested positive for West Nile virus in Suffolk County this year, but no horses.
Samples have also tested positive in Jamesport and Aquebogue, as well as previously in Mattituck, this year.
West Nile virus, first detected in birds and mosquito samples in Suffolk County in 1999 and again each year since through 2012, is transmitted to humans by the bite of an infected mosquito.
“The past weeks of unseasonably warm weather seem to have prolonged the virus and mosquito activity,” Dr. Tomarken said. “Therefore, residents should continue to do their best to reduce the mosquito population around their homes.”
To reduce the mosquito population around homes, residents are urged to eliminate stagnant water where mosquitoes breed by disposing of tin cans, plastic containers, ceramic pots or similar water-holding containers, removing all discarded tires on property, ensuring roof gutters drain properly, and cleaning clogged gutters.
In addition, plastic wading pools and wheelbarrows should be turned over when not in use, birdbath water should be changed, vegetation and debris should be cleaned from the edges of ponds, shrubs and grass should be trimmed, pools, saunas and hot tubs should be cleaned and chlorinated, and water should be drained from pool covers.
Although, according to Dr. Tomarken, most individuals infected with West Nile virus will experience mild or no symptoms, 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 who are most at risk are those 50 years of age or older or those with compromised immune systems; they 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 outdoors for long periods of time, or when mosquitoes are more active, use mosquito repellent when outdoors, and make sure all windows and doors have screens, and that all screens are in good shape.
