County health director Eddie Olivarez says of the 26 mosquito varieties found in the Valley, three are carriers of viruses such as Zika and West Nile.

The department on Thursday told the city that collections from Worcester and Auburn carried West Nile Virus. The infected mosquitoes were collected from one trap in the Town of Ramapo during the week of June 29th as part of the County's ongoing West Nile Virus surveillance efforts. Use a repellent with DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), IR3535 or oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] according to the instructions on the product label.

Wear long, loose and light-colored clothing.

For standing water that can not be drained, use microbial larvicides commonly called "dunks" that kill mosquito larvae before they emerge as adults.

Other precautions people can take to minimize mosquito exposure are to fix or replace all window and door screens to keep mosquitoes outside, and reduce or eliminate all standing water.

Mosquito pools that tested positive for WNV were collected from the Fairmont Park, Lafayette Shores, Norfolk Industrial Park and Edgewater areas. Common symptoms include fever, nausea, headache and muscle ache. Although a person's chances of getting sick are small, those 50 and older are at highest risk for serious illness. Residents can also call the Health Department's West Nile hotline to report areas of stagnant water, report locations of dead birds, and obtain more information on the signs and symptoms of West Nile virus.
