Another case of a mosquito-borne illness called Jamestown Canyon Virus has been identified in New Hampshire. The diagnosis, which was made in the Lakes Region, is the second case of so-called JCV in the state this year. The first was in Kingston in August.

It's the eighth incidence of the disease in New Hampshire since 2013. Officials say reports of human JCV infections are on the rise. The virus mainly causes mild flu-like symptoms but can lead to more severe or fatal nervous system issues in some cases.

Officials say there's a risk of mosquito bites carrying JCV and other diseases well into fall - until there have been two hard, statewide frosts.

Disease-carrying tick bites are also possible until snow season, while temperatures are above freezing.
