This past summer, staff at the Louisville Zoo noticed their three-year-old African elephant, Fitz, was less active than usual. A blood test confirmed that he had elephant endotheliotropic herpesvirus (EEHV), which can cause a deadly hemorrhagic disease. The staff in Louisville and at zoos around the country rushed to help, but despite antiviral medications, plasma transfusions, and other supportive therapies, Fitz died only a few days later.
