World Reference Center for Emerging Viruses and Arboviruses (WRCEVA)

What Services Does this Resource Provide?

The WRCEVA program maintains the Emerging Viruses and Arboviruses Reference Collection and provides reagents and support for investigations of virus outbreaks throughout the world. This international program identifies and characterizes numerous arboviruses and/or other suspected emerging viruses spread by mosquitoes, ticks, and other insects and animals to people and domestic animals. It also investigates the epidemiology of the diseases these viruses cause. The repository within the WRCEVA stores over 7,000 arthropod-borne, rodent-borne, and other zoonotic and human viruses, as well as complementary sera (e.g., hyperimmune mouse ascites fluids), diagnostic antigens, arthropod cell lines, and reagents (viral nucleic acids, infected/inactivated cell supernatants, etc).

The services are provided at University of Texas Medical Branch at Galveston.​
