In a concerning development, health officials in the Northeast have identified cases of the mosquito-borne virus Eastern equine encephalitis (EEE), with one fatality reported in New Hampshire and two additional infections in neighboring states this summer. EEE, similar to West Nile virus, is transmitted through mosquito bites, but it carries a higher death rate and is more rare. This has prompted health officials to issue warnings and urge residents to take precautions during peak mosquito activity hours between dusk and dawn.

The recent death in New Hampshire marks the first reported EEE infection in the state since 2014, when three human cases, including two fatalities, were recorded. Meanwhile, in Vermont, a man in his 40s from Chittenden County was identified as the first case in the state since 2012. Thankfully, he was discharged from the hospital after a week. Massachusetts also witnessed its first case of EEE this year, involving an elderly man who had been exposed in Worcester County.

According to the Centers for Disease Control and Prevention (CDC), there is no specific treatment available for EEE, and approximately 30% of those infected with the virus succumb to the illness. Even survivors can experience long-term neurological complications. Though EEE cases are rare in the United States, mostly limited to eastern and Gulf Coast states, the recent outbreaks in these northeastern states have alarmed health authorities.

To minimize the risk of EEE infection, residents in high-risk areas are advised to stay indoors during mosquito activity hours, wear long pants, long-sleeve shirts, and socks when outdoors, and use mosquito repellent. Additionally, it is crucial to inspect and repair window screens to prevent mosquito entry and eliminate any standing water sources on properties.

Mosquitoes carrying the EEE virus are typically found in and around freshwater hardwood swamps, so individuals residing in areas with such habitats should remain particularly vigilant. The risk of EEE persists until the arrival of the first hard frost, which effectively puts an end to mosquito activity.

While most people who are bitten by an infected mosquito do not show any symptoms, those who do experience fever, chills, body aches, joint pain, and potentially severe neurological conditions such as meningitis and encephalitis. Experts emphasize that only a small percentage of infected individuals develop the most severe form of the disease, namely encephalitis.

Massachusetts, with 10 municipalities classified as high or critical risk for EEE, has implemented an extensive surveillance system for monitoring mosquito-borne viruses. However, health officials caution that the absence of reported cases in certain states may be attributed to less robust surveillance rather than the absence of the virus altogether.

As a preventive measure, some towns have taken additional steps to safeguard their communities. Plymouth has closed all parks and fields during dusk to dawn hours, while Oxford has advised residents to avoid outdoor activities during the same timeframe. Additionally, targeted pesticide spraying is being conducted in certain areas to control mosquito populations.

In response to the outbreak, health officials in Vermont are intensifying mosquito collection and testing efforts, particularly in Chittenden, Grand Isle, and Franklin counties, and urging residents in these areas to take extra precautions. In New Hampshire, residents are being advised to exercise caution when spending time outside.

As the threat of Eastern equine encephalitis looms in the Northeast, it is vital for individuals to prioritize their safety by adhering to the recommended precautions. Staying informed and vigilant is key to protecting oneself from this potentially deadly virus.
