So far this summer, mosquitoes carrying West Nile virus have been detected in four Vermont communities: Springfield, Hartford, Putney and Montpelier.

While no infected mosquitos have been identified in Pittsford this year, that town has undertaken a new mosquito larva surveillance program.

The Lemon Fair Insect Control District exists to do one thing: keep down the mosquito population. It's primary tool for getting this job done is areal larvicide application. So it's not a good sign for the financial viability of the district that it has decided to sell the airplane which it uses to spray the wetlands where mosquito larva thrive.

The Vermont Department of Health has found its first batch of mosquitoes of the year carrying the Eastern Equine Encephalitis (EEE) virus. The virus was detected in mosquitoes trapped in Grand Isle on June 17, making this the earliest detection of EEE in the Northeast as well as the first detection of the virus in Grand Isle County.

If you own a horse, the veterinarians at the Vermont Agency of Agriculture are urging you to vaccinate your animal for two mosquito-borne illnesses: Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV).

State officials announced today that a horse in Swanton died on Aug. 27 of Eastern Equine Encephalitis, commonly known as EEE.

In a release from the Vermont Department of Health, Commissioner Harry Chen said people in Highgate and Swanton are "considered to be at high risk for EEE, based on this evidence."

Health department spokesman Robert Stirewalt said the state would not release the exact name or location of the farm, but confirmed that it was in Swanton. 

The state has detected eastern equine encephalitis (EEE) in more mosquitoes collected in areas of Whiting, Leicester and Brandon.

The viral disease is transmitted by mosquitoes and the three towns in Rutland and Addison Counties are considered hotspots for EEE.

But state infectious disease epidemiologist Erica Berl says there’s evidence the virus is much more widespread.

Vermont Health Commissioner Dr. Harry Chen has ordered aerial spraying, twice in the next five days, aimed at killing mosquitoes carrying the Eastern Equine Encephalitis (EEE) virus.

Dr. Chen released the following statement this week:

A total of five mosquito pools collected in the swampy area of Whiting in southern Addison County have tested positive for Eastern Equine Encephalitis (EEE) virus.

Nearly 100 people met in Brandon Wednesday evening to hear how the state plans to fight Equine Encephalitis or EEE - the mosquito borne illness that caused two deaths in Rutland County last year.

State Health Commissioner Harry Chen said those tragic deaths ushered in a new reality in Vermont that the state is taking very seriously.

“I think it was vitally important for us to come back here,” said Chen, “and show you what we’ve done throughout the winter in terms of planning, in terms of building resources and capabilities to better address that new reality.”


In Brandon on Wednesday, Vermont health and agriculture officials will discuss a new plan to monitor and react to the threat of viruses spread by mosquitoes. The State of Vermont 2013 Arbovirus Surveillance & Response Plan details how state officials plan to work with the U.S. Department of Agriculture Wildlife Services to track and respond to incidents of Eastern Equine Encephalitis (EEE) and West Nile Virus.
