BURLINGTON – The Vermont Department of Health announced today that mosquitoes from the town of Leicester Junction in Addison County have tested positive for West Nile virus.

“This is the first evidence of West Nile virus in Vermont this year, and the hot, dry weather this summer could mean more mosquitoes may be infected than in the past few years,” said State Epidemiologist Patsy Kelso.

The mosquitoes were captured in a trap set on July 27. No human cases of West Nile Virus in Vermont have been confirmed since 2003. The state tests dead birds, traps and tests mosquitoes, and tests people and horses that have symptoms consistent with the virus.

The Health Department recommends that people take precautions to avoid mosquito bites, since the virus is spread by the bite of an infected mosquito.

The Department of Health is reminding Vermonters to:

Symptoms of West Nile virus are often mild, but can include high fever. Approximately 1 percent of people who are infected develop severe illness affecting the central nervous system, such as encephalitis or meningitis, which can be fatal.

The Health Department and the Vermont Agency of Agriculture, Food & Markets are also on the lookout for another mosquito-borne virus, Eastern Equine Encephalitis virus, which has been found in neighboring states and Quebec.
