Which species is most susceptible to vesicular stomatitis?

Vesicular stomatitis is a viral disease primarily affecting livestock, and horses are considered the species most susceptible to this illness. The disease is characterized by vesicular lesions, and while it can also affect cattle and swine, horses tend to show more severe clinical signs and are more frequently impacted by outbreaks. This heightened susceptibility in horses is due to their specific immune response and the types of lesions that commonly occur, which can lead to complications such as pain, difficulty eating, and secondary infections.

The other species, while they can be affected, generally do not exhibit the same level of severity or clinical manifestation as horses. For example, while cattle can contract the virus and show lesions, the overall incidence and impact of the disease in horses remains higher. Therefore, identifying horses as the most affected species aligns with observed veterinary and epidemiological data regarding vesicular stomatitis.
