A surveillance system is used to examine public health issues across several years, track trends, compare health among groups of people, and determine whether something is improving or worsening for a specific group of people. As an Epidemiologist, would you choose active, passive or sentinel surveillance system? Whichever you choose, tell the interviewer why and what the outcome was.

I will talk about setting up surveillance for infectious diseases among young children. For example, I will talk about hand, foot, and mouth disease that is commonly seen among young children. I would first start off with my goal for the system and then break it down with objectives, identify indicators that will be collected from this surveillance system, and set up descriptive EPI analysis to identify disease distribution among the children.

Nice! Your response clearly outlines how you would design and implement this type of surveillance system. Do you have any actual experience designing this type of system that you can also talk about? Perhaps mention the specific goal, objectives, and indicators that you would use in this scenario too. Remember, the more details you provide, the more memorable your answer will be to the interviewer. Great job!
