Our participation in the Tidewater Regional Arboviral Surveillance Program helps us detect the presence of Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV). We catch mosquitoes with carbon dioxide (CO2)-baited Centers for Disease Control (CDC) traps, sort according to species, and pool the species capable of viral transmission. We then send the pools to the Norfolk Department of Public Health Lab for testing. We also submit serum samples from sentinel chicken flocks to test for each virus.
