When a vesicular stomatitis virus outbreak is detected, which action is recommended?

• A. Notify authorities and implement quarantine immediately
• B. Wait and see if the outbreak expands
• C. Vaccinate all horses immediately
• D. Move animals to new pastures

Answer: (A)

The key idea is that rapid regulatory action and strict biosecurity are essential when a vesicular disease is suspected. When vesicular stomatitis virus is detected, notify authorities and impose quarantine immediately to activate official reporting, confirm the diagnosis, and restrict movement of animals, fomites, and people. This kind of early containment helps prevent spread to new herds and regions and allows state and federal veterinary authorities to coordinate surveillance, testing, and disinfection. Waiting to see if the outbreak expands leaves little room for control and can permit the virus to move into additional herds, pastures, and even across boundaries, making eventual containment much harder. Vaccinating all horses right away is not the immediate remedy; vaccination decisions are guided by official protocols and can interfere with surveillance by complicating diagnostic interpretation, and vaccines may not be readily available or appropriate in the acute containment phase. Moving animals to new pastures would spread the virus to new locations and contacts, undermining containment efforts.
