The main method TMAD uses to look for the presence of possible diseases in our district is mosquito pooling. This is the process of collecting adult mosquitoes to be identified, separated and tested. TMAD uses CDC and gravid traps to attract and collect adult female mosquitoes. The mosquitoes from each trap are separated by species and samples are then sent to a lab for testing. Currently, the lab tests for West Nile virus (WNV), Eastern Equine Encephalitis (EEE) and St. Louis Encephalitis (SLE).
