The New Hampshire Department of Health and Human Services (DHHS) announces the first human case of Eastern Equine Encephalitis (EEE) this season in a child from Candia. The results of the test were just confirmed over the weekend by the Massachusetts public health lab.

“It is with much sadness that we have to make this announcement,” said DHHS Commissioner Nicholas Toumpas. “Our thoughts go out to the family of this child who is fighting this serious disease. I want to urge New Hampshire residents not to become complacent about taking protective measures against EEE and West Nile Virus (WNV) this season. Just because the weather is getting cooler does not mean the threat has passed.”


DHHS is also announcing a horse in Henniker tested positive for EEE. This is in addition to an alpaca and llama from Candia, and a horse from Bow, and 37 positive mosquito pools. The total number of mosquito pools tested so far this season is 2,970. There have been no positive test results in New Hampshire for West Nile virus this season.

DHHS recently included the following towns on a public health threat list because of EEE: Allenstown, Atkinson, Auburn, Barrington, Bedford, Bow, Brentwood, Candia, Chester, Chichester, Concord, Danville, Deerfield, Derry, Dover, Dunbarton, Durham, East Kingston, Epping, Epsom, Exeter, Fremont, Greenland, Goffstown, Hampstead, Hampton, Hampton Falls, Hooksett, Hopkinton, Hudson, Kensington, Kingston, Lee, Litchfield, Londonderry, Madbury, Manchester, Merrimack, Nashua, New Castle, Newfields, Newington, Newmarket, Newton, North Hampton, Northwood, Nottingham, Pelham, Pembroke, Plaistow, Portsmouth, Raymond, Rye, Salem, Sandown, Seabrook, South Hampton, Stratham, and Windham.

This public health threat declaration allows for expedited permitting for mosquito control and allows the State to reimburse cities and towns for up to 25% of their costs associated with mosquito control and abatement if local communities have an approved mosquito control plan and the State determines that there is a threat to residents from mosquito-borne illnesses.

“This increase in EEE activity in the State in recent weeks has been disturbing, so it is important that people remember to wear repellent when outside everywhere in the State not just in the towns covered by the public health threat declaration,” said Dr. Jose Montero, Public Health Director at DHHS. “EEE and West Nile are a continued concern until there is a hard frost statewide, which could be quite a few weeks away.”
