The virus that causes Eastern Equine Encephalitis (EEE) has been found in mosquitoes in New Hampshire for this first time this season, as Massachusetts confirms the first human case of the disease since 2013.

The infected New Hampshire mosquitoes were found recently in Pelham, on the Massachusetts border.

EEE is one of three mosquito-transmitted diseases present in New Hampshire, along with West Nile Virus and Jamestown Canyon virus.

Since 2004, 15 people have been infected with EEE in New Hampshire, although none since 2014. This year there have been no EEE infections identified in humans or animals.

On Monday, Massachusetts officials said a 60-year-old male has come down with the disease, which can cause a flu-like illness or in some cases a central nervous system infection such as meningitis and encephalitis (inflammation of the brain). There is no specific treatment for the disease. EEE is more commonly found in eastern Massachusetts than in New Hampshire.

“People need to take steps to prevent mosquito bites, including avoiding being outdoors at dawn and dusk when mosquitoes are most active, wearing protective clothing, using an effective mosquito repellant on exposed skin, and removing standing water from around the home where mosquitoes reproduce,” said NH State Epidemiologist Dr. Benjamin Chan.

Fact Sheets on EEE and other insect-born diseases are available on the DHHS website at dhhs.nh.gov.
