What strategy is sometimes justified for pests that affect public health?

• A. Suppression
• B. Containment
• C. Eradication
• D. Prevention

Answer: (C)

When pests have a direct impact on public health, the goal is to remove the threat entirely. Eradication is the only approach that can permanently eliminate the possibility of transmission, ending the health risk and avoiding ongoing control costs and effort. This makes it the best choice when it’s realistic to achieve global or regional removal and the benefits outweigh the resources required.

Suppression reduces pest numbers but doesn’t guarantee they won’t rebound, so health risks can persist. Containment aims to keep the pest within certain areas but stops short of eliminating the threat everywhere. Prevention lowers the chance of introduction or spread but doesn’t address pests that are already present or the ongoing risk.

So, eradication stands out as the strategy that, when feasible, can provide a lasting safeguard for public health by removing the pest completely.
