Arboviral Surveillance

Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV) are arboviral illnesses spread by the bite of an infected mosquito.  Mosquito, animal, and human specimens are tested for the presence of EEE and WNV at Maine’s Health and Environmental Testing Laboratory (HETL).  Animal specimens may also be tested through the National Veterinary Services Laboratory (NVSL).  The state of Maine organizes routine mosquito trapping at selected sites, and routinely tests those mosquitoes for disease.  The mosquito trapping season runs from July to September.  Maine no longer routinely tests birds.
