背景：你是护理学跨考公共卫生（重大传染病临床研究方向），考研复试现场，老师正在提问你 问题：大学你最喜欢哪门课（流行病学），说出原因，最好能讲个故事（英文）

Well, my favorite course in college was definitely epidemiology. There were a few reasons for this, but I'll share a quick story that really helped solidify my interest in public health.

During my sophomore year, there was a big outbreak of norovirus on campus. It spread quickly and affected a lot of students, including some of my friends. I remember feeling really frustrated and helpless, but then I started learning about how disease outbreaks are investigated and controlled.

In my epidemiology class, we talked about how public health officials use surveillance data, contact tracing, and other strategies to identify the source of an outbreak and prevent it from spreading further. I was fascinated by the way that science and public health policy could work together to protect communities.

Since then, I've been really drawn to infectious disease research and epidemiology. I think it's such an important field, especially given the current global health challenges we're facing.
