Blydenburgh County Park Advised to Suspend Nighttime Activities as Mosquito Sample Tests Positive for West Nile Virus

Three birds test positive for West Nile virus

Suffolk County Health Commissioner Dr. James L. Tomarken announced today that a mosquito sample from Blydenburgh County Park in Smithtown (1) tested positive for West Nile virus. The sample, a Culex pipiens-restuans was collected on July 21, 2015. Suffolk County Commissioner of Parks Greg Dawson has been notified and advised to suspend activities at the park during the hours of 6 p.m. and 8 a.m.

In addition to the positive mosquito sample from Blydenburgh Park, six other mosquito samples and three birds have tested positive for West Nile virus. The mosquito samples, all Culex pipiens-restuans, were collected on July 22nd from West Islip (1), East Northport (1), Lindenhurst (1), West Babylon (1) and Copiague (2). The birds, all American crows, were collected on July 21st and July 24th from East Northport (2) and on July 22nd from Bay Shore (1).  

To date this year, 19 mosquito samples and 3 birds have 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 urge residents to cooperate with us in our efforts to reduce the exposure to the virus, which can be debilitating to humans.”

To reduce the mosquito population around homes, residents should try to eliminate stagnant water where mosquitoes breed:

·       Dispose of tin cans, plastic containers, ceramic pots or similar water-holding containers.

·       Remove all discarded tires on the property. 

·       Make sure roof gutters drain properly, and clean clogged gutters.

·       Turn over plastic wading pools and wheelbarrows when not in use.

·       Change the water in birdbaths.

·       Clean vegetation and debris from the edges of ponds and keep shrubs and grass trimmed.

·       Clean and chlorinate swimming pools, outdoor saunas and hot tubs.

·       Drain water from pool covers.

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 outdoors for long periods of time, or when mosquitoes are more active.

·       Use mosquito repellent when outdoors, following label directions carefully.

·       Make sure all windows and doors have screens, and that all screens are in good repair.

Dead birds found on area properties may indicate the presence of West Nile virus in the area. To report dead birds, call the West Nile virus hotline in Suffolk County at 631-787-2200 from 9 a.m. to 4 p.m., Monday through Friday.  Residents are encouraged to take a photograph of any bird in question.
