High-Risk Massachusetts Cities Grapple with West Nile Virus

West Nile virus poses a significant risk in 10 Massachusetts cities and towns, including Boston. A recent map from the state’s Department of Public Health highlights these areas as high-risk zones. So far this summer, over 150 mosquito samples have tested positive for the virus, but no human cases have been reported.

The virus is spread through mosquito bites and can cause severe symptoms like brain inflammation or meningitis in about 1% of reported cases. People over 50 are more likely to develop severe illness. Last year, there were 19 confirmed cases in Massachusetts.

In addition to West Nile, Eastern equine encephalitis (EEE) has also been detected in mosquito samples. EEE is a rare but deadly disease that claims the lives of about 30% of those infected. While no towns are at high risk for EEE, 12 are considered moderate-risk zones.

To avoid mosquito bites, health officials recommend using insect repellent when outdoors, staying indoors during peak hours (dawn and dusk), and wearing long sleeves and pants.
