Who we are

Our staff includes entomologists, epidemiologists, molecular biologists, laboratorians, microbiologists, physicians, veterinarians, virologists, and zoologists.
What are vector-borne diseases?
Almost everyone has been bitten by a mosquito, tick, or flea. Vectors are mosquitoes, ticks, and fleas that spread pathogens. A person who gets bitten by a vector and gets sick has a vector-borne disease. Some vector-borne diseases, like plague, have been around for thousands of years. Others, like Heartland virus disease and Bourbon virus disease, have been discovered recently.
