A robovirus is a zoonotic virus that is transmitted by a rodent vector (i.e., "ro"dent "bo"rne).

Roboviruses mainly belong to the Arenaviridae and Hantaviridae family of viruses. Like arbovirus ("ar"thropod "bo"rne) and tibovirus ("ti"ck "bo"rne) the name refers to its method of transmission, known as its vector. This is distinguished from a clade, which groups around a common ancestor. Some scientists now refer to arbovirus and robovirus together with the term ArboRobo-virus.

Rodent borne disease can be transmitted through different forms of contact such as rodent bites, scratches, urine, saliva, etc. Potential sites of contact with rodents include habitats such as barns, outbuildings, sheds, and dense urban areas. Transmission of disease through rodents can be spread to humans through direct handling and contact, or indirectly through rodents carrying the disease spread to ticks, mites, fleas (arboborne.
