Classification of cases

Premises that have laboratory diagnostic confirmation of VSV are categorized as confirmed positive premises. According to USDA, once a county is confirmed as VSV-positive, new equine premises presenting with clinical signs of VSV in that county are not required to be tested for confirmation of the disease, but the premises will be quarantined and classified as a suspect premises.

Report to KDA

VSV is considered a reportable disease in Kansas.
