The Massachusetts Department of Public Health (MDPH) announced that West Nile Virus (WNV) has been detected in mosquitoes collected from North Attleborough. In 2024, 8,597 mosquito samples were tested for WNV and 333 samples were positive. North Attleborough had a total of two (2) WNV positive mosquito samples identified in 2024, also in August.
WNV is most commonly 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, people over the age of 50 are at higher risk for severe infection. Â
By taking a few precautions, people can help to protect themselves and their loved ones.
- Apply Insect Repellent when going 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.
- 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 outdoors at any time and notice mosquitoes around, take steps to avoid being bitten by moving indoors, covering up and/or wearing repellant.
- Many mosquitoes lay their eggs in standing water. Limit the number of places around the 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. Â
- Some mosquitoes like to come indoors. Keep them outside by having tightly-fitting screens on all windows and doors.
The North Attleborough Health Department works closely with the MDPH and other agencies, and is educating the public, notifying partners at the Park and Recreation Department, Hockomock YMCA, and facilities with vulnerable populations.
