Finding Leads to Increase in Public Risk

Concord, NH - The New Hampshire Department of Health and Human Services

(DHHS) today announced a positive test result for eastern equine

encephalitis (EEE) in a horse in the northeastern town of Ossipee. This

finding raises the risk level for the town of Ossipee from “Remote” to

“High.” The surrounding towns of Tamworth, Madison, Freedom, Effingham,

“This is not the first animal in New Hampshire to test positive for EEE

this season,” said DHHS Public Health Director Dr. José Montero, “however

this particular finding is in an area of the State where we haven’t had

positive EEE results in several years. This underscores the importance for

everyone, no matter where you live in the State, to take steps to prevent

mosquito bites until there is a killing frost statewide.”

So far this season New Hampshire’s Public Health Lab has tested 4717

batches of mosquitoes. Of those, 20 tested positive for EEE and 13 tested

positive for West Nile Virus (WNV). One person was diagnosed with WNV, and

one other horse has tested positive for EEE.

EEE is a serious disease that carries a high mortality rate for those who

contract the serious encephalitis form of the illness. Symptoms may

include high fever, severe headache, and stiff neck. There is no treatment

for the disease, which can lead to seizures and coma. Symptoms usually

occur 4 to 10 days after being bitten. Symptoms of WNV disease often

appear 4 to 10 days after being bitten. If you or someone you know is

experiencing flu-like symptoms, including fever and headache, contact your

local medical provider.
