A mosquito sample in West Islip has tested positive for West Nile virus, the Suffolk County Health Services Department reported on Friday. The sample was collected between July 10 and July 12.
James L. Tomarken, Health Services commissioner, said residents may reduce mosquito populations around homes by eliminating stagnant water where mosquitoes breed.
The county offers a bulletin entitled “Mosquitoes and Mosquito-borne Illnesses,” which contains tips on personal protection and repellents.
To date this year, 30 mosquito samples — all Culex pipiens-restuans — and six birds have tested positive for the virus. There have been no human cases reported in the county this year.
West Nile virus, first detected in birds and mosquito samples in Suffolk County in 1999 and again each year thereafter through 2011, is transmitted to humans by the bite of an infected mosquito.
