Which statement best aligns with managing wildlife diseases to protect domestic animals?

• A. Prevention is the most effective strategy, even if challenging to implement
• B. Treatment after infection is enough
• C. Vaccination alone cures all risks
• D. Active surveillance alone prevents transmission

Answer: (A)

Preventing disease from entering or spreading between wildlife and domestic animals is the most effective approach because it cuts off the opportunity for transmission at its source. When prevention is strong—think robust farm biosecurity, securing feed and waste, minimizing wildlife access to markets and pastures, fencing or barriers, and careful management of habitats—the risk of spillover drops dramatically and you reduce outbreaks before they start. Treating after infection helps, but by the time disease is detected, transmission may already be underway, and outbreaks can escalate quickly, especially with wildlife reservoirs that continually reintroduce pathogens. Vaccination is a valuable tool for reducing susceptibility, but it cannot guarantee complete protection—coverage gaps, vaccine effectiveness limits, and pathogen evolution can leave openings for transmission. Surveillance is essential for early detection and rapid response, yet alone it doesn’t prevent transmission; actions to reduce contact and exposure are still needed. So prioritizing prevention keeps the threat from wildlife away from domestic animals as effectively as possible, even when implementation is challenging.
