The Massachusetts Department of Public Health (MDPH) has confirmed the presence of West Nile Virus (WNV) in mosquitoes collected in Sudbury, raising the town’s risk level to moderate. No human cases have been reported.
The news came by way of a press release from the Sudbury Health Department, which coordinates mosquito control activities with the East MiddleSex Mosquito Control Project in addition to many other public health services ranging from food service inspection and permitting to inspection of septic systems, community nursing and mental health services.
According to the announcement, West Nile Virus is spread through mosquito bites and can affect both humans and animals. While most people infected do not experience symptoms, some may develop mild flu-like illness, and in rare cases, the virus can lead to serious neurological conditions.
Local and state officials are urging residents to take precautions against mosquito bites. Recommended steps include using insect repellent, wearing long sleeves and pants when outdoors, and being especially cautious during peak mosquito activity hours between dusk and dawn. Families are also reminded to check product labels before applying repellents on children, as some are not recommended for infants or young children.
Preventing mosquito breeding is another key defense. Residents are advised to eliminate standing water around their homes by emptying unused flowerpots, wading pools, and birdbaths, and ensuring gutters and drains are clear. Installing or repairing window and door screens can also reduce the risk of mosquitoes entering homes.
Sudbury is working with the East Middlesex Mosquito Control Project to increase mosquito surveillance and reduce risks locally. Information on current and historical WNV activity in Massachusetts is available at mass.gov/info-details/massachusetts-arbovirus-update
