DHHS: West Nile Virus Found in 26 Mosquito Batches


Eighteen new batches of mosquitoes have tested positive for West Nile Virus in the greater Manchester, Nashua and Salem areas.

The state epidemiologist says this is the first announcement of West Nile Virus from the state this year. The city of Manchester has already reported 8 mosquito batches that tested positive. That brings the state total so far to 26, 23 in Manchester alone. 2 batches tested positive in Nashua and 1 in Salem.

Last year New Hampshire only found a total of 9 positive batches.

According to the state’s Risk Map, Manchester is now at a “high” risk level with the bordering towns of Goffstown, Bedford, Londonderry, Auburn and Hooksett listed at “moderate” risk. Salem and Nashua have positive batches but are at a “low” risk level.

West Nile Virus is transmitted by mosquito bite and the flu-like symptoms appear 4 to 10 days after being bitten.
