BURLINGTON, Vt. (WCAX) – Despite colder temperatures, Eastern equine encephalitis — and the mosquitos that transmit it — are still a concern in certain Vermont communities.
Vermont health officials say that in order to kill off the mosquitos, a town must spend two hours below 28 degrees, which causes a hard frost. Many towns — especially those at high risk — haven’t been that cold yet.
While the number of mosquitos is decreasing significantly, the health department’s Patsy Kelso says it’s still important to take precautions. “Mosquitoes are still active, especially in some areas of the state. They are less active, but they’re still around, and some of those mosquitoes are still carrying triple-e. So, while we’re enjoying the cooling weather, be sure still to be aware, and if there are mosquitoes out, take precautions to prevent bites,” she said.
There have been two human cases of triple-e in Vermont this year and one death.
Officials say a horse in Orleans County tested positive Friday, marking the second equine case of 2024.
