WESTBOROUGH – On Tuesday, Aug. 6, the state’s Department of Public Health has notified the Public Health Department that West Nile virus has been detected in mosquitoes collected from the southwest quadrant of town.
WNV is most transmitted to humans by the bite of an infected mosquito. The mosquitoes that carry this virus are common throughout the state, and are found in urban as well as more rural areas.
While WNV can infect people of all ages, most people (8 out of 10) infected with West Nile virus do not develop any symptoms; people over the age of 50 are at higher risk for severe infection.
People can help protect themselves and their loved ones by doing the following:
Apply insect repellent when you go outdoors. 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. DEET products should not be used on infants under 2 months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under 3 years of age.
Permethrin products are intended for use on items such as clothing, shoes, bed nets and camping gear, and should not be applied to skin.
Clothing can help reduce mosquito bites. Although it may be difficult to do when it’s hot, wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.
Be aware of peak mosquito hours. The hours from dusk to dawn are peak biting times for many mosquitoes. When risk is increased, consider rescheduling outdoor activities that occur during evening or early morning. If you are outdoors at any time and notice mosquitoes around you, take steps to avoid being bitten by moving indoors, covering up and/or wearing repellant.
Drain standing water. Many mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by either draining or getting rid of items that hold water. Check rain gutters and drains. Empty any unused flowerpots and wading pools and change water in birdbaths frequently.
Install or repair screens. Some mosquitoes like to come indoors. Keep them outside by having tightly fitting screens on all your windows and doors.
