Concord, NH – The New Hampshire Department of Health and Human Services (DHHS) is announcing that one batch of mosquitoes from Londonderry tested positive for Eastern Equine Encephalitis Virus (EEE). This is the first finding of EEE in the State this year. There have not been any positives identified for West Nile Virus so far this season in New Hampshire. In 2013, there were 27 positives for EEE, including 24 mosquito batches and 3 animals.

EEE and WNV are transmitted by the bite of infected mosquitos. This finding does not change the current low arboviral risk level for Londonderry. It is important that people continue to take precautions against mosquito bites including wearing an effective repellent, long pants and sleeves, ensuring screens are in good repair and removing standing water from your property to prevent mosquitoes from breeding.

"This is approximately the same time we identified the first positive for Eastern Equine Encephalitis as last year," said Public Health Director Dr. JosÉ Montero. "Since we know that the agents that cause these diseases are here in New England, everyone should make it part of their routine to take precautions every time they go outside."

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. EEE is a more 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, stiff neck, and sore throat. There is no treatment for the disease, which can lead to seizures and coma. Symptoms usually occur 4 to 10 days after being bitten.
