1st Batch of Mosquitoes Collected From NH Town Tests Positive For West Nile Virus

The New Hampshire Department of Health and Human Services has identified the first batch of mosquitoes this year to test positive for West Nile Virus.

The department says the batch was collected in Manchester on Aug. 21.

DHHS is working with the City of Manchester Health Department to notify Manchester residents and those in the surrounding towns of the positive WNV test.

State Epidemiologist Benjamin Chan says until there’s a statewide mosquito-killing frost, the risk of infection by mosquito-borne viruses will increase.

West Nile Virus was first identified in New Hampshire in 2000. Symptoms usually appear within a week after being bitten and can include flu-like illness, including fever, muscle aches, headaches, and fatigue. Many people may not develop any symptoms, or only develop very mild symptoms.
