Concord, NH – The New Hampshire Department of Health and Human Services (DHHS) is announcing that a batch of mosquitoes from Sandown has tested positive for Eastern Equine Encephalitis (EEE). This is the first finding of EEE in the State this year and the first time since 2010 when one animal tested positive. This is in addition to the 38 batches of mosquitoes that have tested positive for West Nile Virus this season in New Hampshire.
EEE and WNV are transmitted by the bite of an infected mosquito. WNV was first identified in New Hampshire in August of 2000 and EEE was first identified in 2004.
“This is the first identified positive for Eastern Equine Encephalitis in New Hampshire this season, but unfortunately it is not unexpected,” said Public Health Director Dr. José Montero. “What is different is that the U.S. is seeing an unprecedented outbreak of West Nile Virus this year and that is even more reason why people should take precautions against being bitten by mosquitoes.”
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.
Under the recommendation of DHHS, Governor Lynch signed a Public Health Threat declaration for numerous communities in New Hampshire due to the detection of positive WNV mosquito batches. Under State statute, this declaration allows towns to continue to take prevention measures to address this threat including spraying to reduce the number of mosquitoes.
