Eight new mosquito samples have tested positive for West Nile virus, including two in Aquebogue, Suffolk County Health Commissioner Gregson Pigott said yesterday.

Of the positive samples, seven were Culex pipiens-restuans collected on Aug. 30 and Aug. 31 from Melville (1), Dix Hills (2) Bay Shore (2), and Aquebogue (2). One positive sample of the Culex erraticus species was collected on Aug. 31 from Nesconset (1).

One bird, an American Crow, found on Aug. 31 at Blue Point Beach, Fire Island, also tested positive for the virus.

To date this year in Suffolk County, 77 mosquito samples have tested positive for West Nile virus, one mosquito sample tested positive for Jamestown Canyon virus and one bird 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.

Suffolk County reported 11 cases of West Nile virus in 2022 and 8 in 2021. Nine people have died from West Nile virus since 2000.

For more information about West Nile virus in Suffolk visit the county health department’s website.

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.

Jamestown Canyon virus is spread to humans by the bite of an infected mosquito. Fever, headache and fatigue are common symptoms of Jamestown Canyon virus. Symptoms of severe disease may include stiff neck, confusion, loss of coordination, difficulty speaking, or seizures. There are no vaccines to prevent the virus. The treatment is supportive care.

Though Suffolk County has no reported cases of Jamestown Canyon virus, this virus has been isolated in mosquito samples in 2008, 2017 and 2022. Residents are advised to take precautions to avoid mosquito bites. More information on Jamestown Canyon virus can be found on the CDC website.

“The finding of Jamestown Canyon virus or West Nile virus in mosquito samples indicates the presence of that virus in the area,” Pigott said. “While there is no cause for alarm, we advise residents to take precautions and cooperate with us in our efforts to reduce exposure to mosquito-borne diseases.”

The health commissioner urged people age 50 or older and those with compromised immune systems to take precautions to avoid being bitten by mosquitoes.

Avoid mosquito bites in the following ways:

  • 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.
