State health officials have identified a batch of mosquitoes in Manchester with the virus Eastern Equine Encephalitis (EEE).
This is the third detection of EEE in New Hampshire this season, and the first in Manchester since 2013. There have been no reports of human cases of the virus so far.
EEE is less common but more serious than the mosquito-born West Nile Virus. Symptoms are flu-like and appear four to 10 days after being bitten.
The Manchester Health Department says as of now, it is does not plan to spray for mosquitoes, but it will continue to monitor mosquitoes for EEE until mid-October.
