Hauppauge, NY – Suffolk Health Commissioner James Tomarken and Parks Commissioner Greg Dawson have taken the precautionary measure of closing Blydenburgh County Park to nighttime activities following the news that a mosquito sample has tested positive for West Nile virus. The park will be closed from 6 p.m. to 8 a.m. and all activities during those hours will be suspended. The Department of Health Services will continue mosquito surveillance at the park and will work closely with the Parks Department to determine if and when nighttime activities may resume.
