Population management aims to reduce disease transmission at the wildlife-domestic interface by which strategy?

• A. Increasing vaccination in domestic animals
• B. Reducing wildlife population size
• C. Expanding habitat
• D. Ignoring wildlife health

Answer: (B)

The main idea is that disease spread between wildlife and domestic animals is strongly tied to how many wildlife animals are present. When wildlife density is high, contact between wildlife and domestic animals is more frequent, making it easier for pathogens to move across the interface. Reducing the wildlife population size lowers contact opportunities and slows transmission, which can bring the outbreak under control by dropping the effective reproduction number below 1. This is a direct density-based approach to interrupting transmission at the wildlife–domestic boundary. Vaccinating domestic animals helps reduce disease risk but doesn’t remove wildlife reservoirs or change how often wildlife and domestic animals meet. Expanding habitat can actually increase wildlife numbers and potential contacts, potentially raising risk. Ignoring wildlife health obviously fails to address transmission pathways.
