NH Arboviral Test Results

EEE and 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 infection at the New Hampshire Public Health Laboratories. Wild bird testing no longer provides useful data for disease surveillance and will not occur on a regular basis.

Positive test results are one of many factors that establish the risk level of mosquito-transmitted disease.
