护理学跨考公共卫生：流行病学是我的最爱，因为它让我看到了改善健康的希望

英文回答：

My favorite course in college was Epidemiology. I was always drawn to the way it combined medicine, statistics, and public health. But what really solidified my love for this field was a story I heard during a lecture on the history of epidemiology.

In the mid-1800s, there was a severe cholera outbreak in London. At the time, many people believed that the disease was spread by 'miasma', or bad air. But one physician, John Snow, suspected that contaminated water was the true culprit. He mapped out the cases of cholera and found that they were clustered around a single water pump on Broad Street. Snow convinced local officials to remove the handle from the pump, effectively cutting off the source of contaminated water, and the outbreak subsided.

This story resonated with me because it demonstrated the power of epidemiology to make a real difference in people's lives. By identifying the source of the outbreak and taking action, John Snow saved countless lives. It reminded me that epidemiology isn't just about studying diseases and statistics, but about using that knowledge to improve public health and save lives.

我在大学最喜欢的课程是流行病学。我一直被它将医学、统计学和公共卫生结合起来的方式所吸引。但真正让我热爱这个领域的是在一堂关于流行病学历史的讲座中听到的一个故事。

19世纪中期，伦敦爆发了一场严重的霍乱疫情。当时，许多人认为这种疾病是由'瘴气'或坏空气传播的。但一位医生约翰·斯诺怀疑受污染的水才是真正的罪魁祸首。他绘制了霍乱病例地图，并发现它们聚集在布罗德街的一个水泵周围。斯诺说服当地官员拆除了水泵的手柄，有效地切断了受污染的水源，疫情得到了控制。

这个故事让我深受启发，因为它展示了流行病学在改善人们生活的能力。通过确定疫情源头并采取行动，约翰·斯诺挽救了无数人的生命。它让我想起，流行病学不仅是研究疾病和统计数据，更是利用这些知识来改善公共卫生和挽救生命。
