Ranid Herpesvirus 3 (RaHV3)
Species: Amphibians especially frogs
Infections with RaHV-1 cause distinctive multifocal, not delineated, light brown to grey, prominent firm skin lesions, especially in frogs. Tadpoles that have been tested positive for the virus appear unaffected. Adult frogs can be inapparent carriers of the disease. The disease is mainly prevalent in the Spring, after hibernation and during mating season. The virus is shed via the skin and the most likely transmission takes place by direct contact.
