Multiple Choice

Where do VSV lesions tend to be located?

VSV infection typically produces a localized vesicle at a single mucocutaneous site, usually on the oral mucosa such as the tongue, lips, or muzzle in horses and cattle. The lesions are not usually widespread, so a single lesion best fits the common pattern. The other options describe distributions that aren’t characteristic: lesions on multiple body sites, exclusive hoof involvement, or an initial respiratory mucosa predilection. Hence, a solitary lesion captures the typical presentation.
