护理学跨考公共卫生复试：流行病学案例分析 - 杭州电梯新冠溯源

英文回答：

My favorite course in college is epidemiology. The reason is that epidemiology provides a systematic approach to understanding the distribution and determinants of health and disease in populations. It helps us to identify risk factors, develop prevention strategies, and evaluate the effectiveness of interventions.

Speaking of epidemiology, there is a fascinating story about how the COVID-19 virus was traced back to an elevator in Hangzhou, China. In January 2020, a woman in Hangzhou was diagnosed with COVID-19, and the source of her infection was unknown. The local health authorities launched an investigation and found that the woman had taken an elevator in her residential building, which was also used by a couple who had returned from Wuhan, the epicenter of the outbreak. The couple had not shown any symptoms of COVID-19, but they were later found to be infected with the virus.

The investigators collected samples from the elevator buttons and found traces of the virus. This discovery led to a wider investigation of the building, which identified several more cases of COVID-19, all linked to the elevator. This story demonstrates the power of epidemiology in identifying the source of an outbreak and taking appropriate measures to control its spread.

我在大学最喜欢的课程是流行病学。原因是流行病学提供了一种系统的方法来理解人群健康与疾病的分布和决定因素。它帮助我们识别风险因素，制定预防策略，并评估干预措施的有效性。

说到流行病学，有一个非常有趣的故事，讲述了新冠病毒是如何追溯到杭州一个电梯上的。2020年1月，杭州市一名女性被确诊为新冠肺炎患者，她的感染来源不明。当地卫生部门展开调查，发现该女性曾乘坐在她住处的电梯，而该电梯也被一对从武汉返回的夫妇使用过。这对夫妇没有表现出任何新冠症状，但后来被发现感染了该病毒。

调查人员从电梯按钮上收集样本，并发现病毒的痕迹。这一发现引发了对整栋建筑的更广泛调查，发现了更多与电梯有关的新冠病例。这个故事展示了流行病学在确定疫情来源并采取适当措施控制传播方面的强大能力。
