In the Incident Command System (ICS), where does preventive medicine fit?

• A. PM supports surveillance, health protection, vaccination, risk assessment
• B. PM handles only medical supply
• C. PM is not part of ICS
• D. PM leads all operations

Answer: (A)

Preventive medicine in the Incident Command System acts as a health protection and public health support function. Its role centers on safeguarding both responders and the affected population by monitoring health conditions, identifying and assessing risks, and implementing preventive actions. This includes establishing and guiding surveillance for disease or illness, conducting risk assessments to prioritize actions, and coordinating vaccination or other protective measures when appropriate. In practice, preventive medicine informs the Incident Action Plan through planning input, supports operations with health protection guidance, and works with logistics to ensure the necessary vaccines, prophylactics, and related supplies are available. This collaborative, cross‑functional involvement fits its role as a health-focused support element rather than leading all operations or handling only medical supply.
