SALEM — Mosquitoes found in Salem have tested positive for the West Nile virus.
The state Department of Health and Human Services announced this afternoon that 18 batches of mosquitoes from Salem, Manchester and Nashua were found to have the virus.
The total number has risen to 26 after eight other batches tested positive in Manchester earlier in the season, according to state health officials. Last year, nine mosquito batches tested positive for West Nile in New Hampshire.
Symptoms often appear four to 10 days after being bitten, the state officials said. Anyone who is experiencing flu-like symptoms, including fever and headache, should contact a doctor.
