State health officials say a batch of mosquitoes in Exeter have tested positive for Eastern Equine Encephalitis, or EEE.
This is the first case of EEE found in New Hampshire this year.
Public Health Director Dr. Jose Montero says the finding is not unexpected and Exeter remains a low risk area.
Still, he cautions people to take precautions against being bitten by mosquitoes.
In addition to the case of triple-E found in Exeter, six batches of mosquitoes have tested positive for West Nile Virus so far this season.
Last year, there were 13 cases of EEE found in New Hampshire, including nine mosquito batches and four animals.
