Which measure is most appropriate to control spread of VSV?

The key idea is that stopping the movement of animals and potentially contaminated materials is the most effective way to interrupt transmission. Vesicular stomatitis virus spreads mainly when infected animals or contaminated equipment and vehicles move between premises. Implementing a movement restriction for about 30 days creates a break in the transmission chain, giving time to detect new cases, isolate affected herds, and allow signs to appear in any recently exposed animals before they can spread the virus further. This aligns with the time window in which animals are exposed and infectious, helping to contain the outbreak regionally. Disinfecting surfaces helps reduce environmental contamination, but it doesn’t address the primary route of spread—the movement of animals and people between farms. Vaccination of exposed animals can be complicated by vaccine efficacy, regulatory constraints, and timing, and vaccinating all exposed animals regardless of these factors isn’t a reliable primary control measure. Doing nothing would let the outbreak spread unchecked and cause more harm.
