Arbovirus Surveillance Program

About Us

The Arbovirus Surveillance Program at the Texas Department of State Health Services is designed to detect the presence of arboviruses in mosquitoes before the development of human disease. Routine arboviral studies are conducted on mosquitoes from May through November each year, with some flexibility due to patterns of detection. This surveillance period has been satisfactory for the detection of arboviruses in Texas. Effective March 31, 2013, Arthropod identification will no longer be performed at the Texas Department of State Health Services Laboratory. Arthropods of medical concern should be addressed to your primary care physician.
