West Nile Virus has been detected in Newton and your risk is rated as MODERATE by the Massachusetts Department of Public Health (DPH) .
The risk level for Eastern Equine Encephalitis (EEE or “Triple E”) remains as “low” in Newton and all cities and towns near Newton.
Eastern Equine Encephalitis (EEE or “Triple E”) and West Nile Virus (WNV) are both mosquito-borne diseases that the Massachusetts Department of Public Health (DPH) says “can cause illness ranging from a mild fever to more serious disease like encephalitis or meningitis.” Massachusetts DPH publishes information about mosquito-borne diseases here: West Nile Virus (WNV) or Eastern Equine Encephalitis (EEE or “Triple E”). DPH posts the test results and assigns a category (ranging from “Remote” to “Critical”) to the risk posed by each virus in each community in the state.
Symptoms of West Nile Virus Infection
According to the CDC, most people (80%) infected with West Nile virus do not develop symptoms. About 20% of people who are infected develop mild flu-like symptoms, such as a fever with headache, body aches, joint pains, vomiting, diarrhea, or rash. Less than 1% of people infected with WNV develop severe illness that affects the central nervous system.

In Newton, the risk for EEE hasn’t risen above “Low” in recent years. However, WNV risk in Newton is more variable, and reached the “High” level by late summer in 2016, 2018, 2020, 2021, and 2025. As the risk level increases, the set of recommended prevention steps changes.
With outdoor activity increasing in summer, it’s a good time to review options for reducing our personal risk level so we can enjoy nature relatively care-free. Here are some precautions we can take:
- Use an EPA-approved repellent when you’re outside. Find the right repellent based on age, activity, and ingredient preference by using this tool from the Environmental Protection Agency.
- Wear long sleeves, long pants and socks to reduce skin exposure outside.
- Remove standing water around your home at least twice weekly to prevent mosquitoes from breeding there.
