An adult from Laconia has tested positive for a mosquito-borne virus, New Hampshire's Department of Health and Human Services says.
The adult tested positive for the Jamestown Canyon virus, which is transmitted by infected mosquitoes, the department said Wednesday. It's the second time a case has been identified in the state this year; it was identified in a Kingston resident in August.
Reports of Jamestown Canyon virus in humans are rare, but have increased over the last several years. This is New Hampshire's eighth case since the state's first report of the disease in 2013.
The department says most illnesses caused by the virus have been mild, but moderate-to-severe central nervous system involvement has been reported, including fatal infections.
