Comments: The Vermont Agency of Agriculture received confirmation this week of a positive Eastern equine encephalitis (EEE) test in a horse. This case is in Orleans County, a location in Vermont that had not previously been identified as having any mosquitoes testing positive for EEE. It is the second horse testing positive this year. The horse was unvaccinated and is now deceased. The horse was tested on October 4. It likely contracted the disease mid-September during a period of warmer than normal weather.;
