Transboundary Emerging and Exotic Animal Disease/ Exotic Animal Disease Practice Exam

What does NOT contribute to the emergence and reemergence of diseases in people?

1. Increasing human population.

2. Enhanced biosecurity practices.

3. Climate change.

4. Globalization of travel and trade.

The correct answer is: Enhanced biosecurity practices.

Enhanced biosecurity practices are designed to prevent the introduction and spread of infectious diseases, particularly those that are transboundary or exotic in nature. By implementing strict measures such as quarantines, routine inspections, and control of animal movements, these practices serve to mitigate the risks associated with the spread of diseases among populations and across borders. In contrast, increasing human populations, climate change, and the globalization of travel and trade are all factors that can facilitate the emergence and reemergence of diseases. As human populations grow, there is a higher likelihood of increased contact between people and animals, which can lead to the spillover of pathogens. Climate change can alter habitats and disrupt ecosystems in ways that promote the spread of vector-borne diseases. Additionally, globalization enhances the movement of goods and people across the globe, making it easier for diseases to spread rapidly. In this context, enhanced biosecurity practices stand out as a protective measure rather than a contributor to disease emergence, highlighting why they are the correct choice in this question.
