West Nile virus has been found in 11 mosquito samples tested by the Suffolk County Department of Health Services.

The mosquito samples came from Bay Shore, Port Jefferson Station, Setauket, Lindenhurst, Copiague and West Babylon.

The samples were collected on July 15 and 16.

So far this year, the department says no humans have tested positive for West Nile virus.

"Everyone is urged to take precautions to avoid mosquito bites," the department wrote, "Individuals 50 and older, as well as those with compromised immune systems, are urged to take precautions to avoid mosquito bites."

The virus is transmitted to humans from the bite of an infected mosquito, with most infected people having mild or no symptoms, the agency said. But sometimes, people can develop mild to severe symptoms and potentially die.

Two dead crows found in Ronkonkoma on June 24 also tested positive for West Nile virus.

The department says dead birds could indicate the presence of West Nile virus.
