The Exeter Town Health Department has received notice that a mosquito which was trapped in the Hobart Street area has tested positive for the West Nile virus. Ken Berkenbush, Exeter town Health Officer says the town does not have any current plans to spray for mosquito’s town wide, but has not ruled out the possibility in the future. 38 batches of mosquitoes have tested positive for West Nile virus just this summer in the Granite State since the first reported case in Manchester in August. Symptoms of West Nile virus often appear in humans four to 10 days after being bitten. Eighty percent of those infected will fail to show symptoms, while 20 percent will develop mild symptoms. One in 150 people infected will develop severe symptoms, according to the New Hampshire Division of Public Health.
