Public health officials in Massachusetts have announced an increased risk of contracting Eastern equine encephalitis (EEE) in several towns across the state. This comes after additional mosquito samples collected in Abington, Middleborough, Wareham, and Whitman tested positive for EEE. As a result, risk levels have been raised to high in Carver and Middleborough, and moderate in Bridgewater, Lakeville, and Rochester.

The detection of EEE in mosquitoes in Massachusetts this year first occurred on July 3 in Carver. EEE is a rare but severe and potentially fatal disease that can affect people of all ages. It is primarily spread to humans through the bite of an infected mosquito.

In recent years, Massachusetts has seen cases of EEE with devastating consequences. In 2019, there were 12 human cases of EEE in the state, resulting in six deaths. The following year, in 2020, there were five human cases and one death. However, no human cases of EEE were reported in Massachusetts in 2021, 2022, or 2023.

To combat the spread of EEE, health officials are urging residents and visitors to take necessary precautions. This includes regularly applying insect repellent outdoors, being aware of peak mosquito activity during dusk and dawn, and wearing long sleeves, long pants, and socks when spending time outside.

For more information on mosquito-borne diseases, including updates on West Nile virus and EEE positive results, residents can visit the Arbovirus Surveillance Information webpage on the official Mass.gov website.

With EEE posing a significant health risk, it is crucial for the community to remain vigilant and take preventive measures to protect themselves and their loved ones from mosquito-borne diseases.
