Introduction:导言：
In the realm of hospital infections, the application of epidemiological principles is indispensable for the effective management and prevention of infectious diseases. Epidemiology, as a scientific discipline, provides a systematic approach to studying the distribution and determinants of health-related events in populations. When applied to the field of hospital-acquired infections, it becomes a powerful tool in assessing risks, identifying patterns, and implementing control measures.
┇在医院感染领域，运用流行病学原理对于有效管理和预防感染性疾病至关重要。作为一门科学学科，流行病学为研究人群中与健康相关事件的分布和决定因素提供了系统化的方法。当应用于医院获得性感染领域时，它成为了评估风险、识别模式和实施控制措施的有力工具。
In the context of healthcare settings, a thorough understanding of epidemiological principles is essential for healthcare professionals to effectively combat hospital-acquired infections. By integrating bilingual learning into their practice, healthcare providers can enhance their knowledge and skills in applying epidemiological methods to investigate and control infectious outbreaks.
┇在医疗环境中，医护人员对流行病学原理的深入了解对于有效应对医院获得性感染至关重要。通过将双语学习融入实践中，医疗提供者可以增强他们应用流行病学方法调查和控制感染性疾病爆发的知识和技能。
Bilingual learning, in this context, refers to the acquisition and utilization of knowledge in both the local language and a second language. In healthcare settings, where multicultural and multilingual interactions are common, bilingual proficiency can facilitate effective communication with diverse patient populations and healthcare professionals. Moreover, bilingual healthcare professionals are better equipped to access and utilize epidemiological research and information available in multiple languages, enabling them to stay updated on the latest developments and practices in infection control.
┇在这一背景下，双语学习指的是获取和运用本地语言和第二语言的知识。在医疗环境中，多文化和多语言交流很常见，双语能力可以促进与不同患者群体和医护人员的有效沟通。此外，双语医护人员更能够获取和利用多种语言的流行病学研究和信息，使他们能够及时了解感染控制领域的最新发展和实践。
Therefore, the integration of bilingual learning with epidemiological principles in the field of hospital infections not only strengthens the abilities of healthcare professionals but also enhances the overall effectiveness of infection control measures. By embracing bilingualism in their professional development, healthcare providers can contribute to the advancement of public health practices and the well-being of individuals in diverse healthcare environments.
┇因此，在医院感染领域，将双语学习与流行病学原理结合起来不仅强化了医护人员的能力，还提高了感染控制措施的整体效果。通过在专业发展中接受双语教育，医疗提供者可以促进公共卫生实践的发展，增进多样化医疗环境中个体的福祉。

四、学习方法
1.General Instructions 一般说明Self-study courses are “self-paced.” We recommend that a lesson be completed within two weeks. To get the most out of this course, establish a regular time and method of study. Research has shown that these factors greatly influence learning ability.自学课程是“自定进度”的。我们建议在两周内完成一堂课。为了充分利用本课程，请建立固定的学习时间和方法。研究表明，这些因素极大地影响了学习能力。Each lesson in the course consists of reading, exercises, and a self-assessment quiz.课程中的每一节课都包括阅读、练习和自我评估测验。2.Reading Assignments 阅读作业Complete the assigned reading before attempting to answer the self-assessment questions. Read thoroughly and re-read for understanding as necessary. A casual reading may result in missing useful information which supports main themes. Assignments are designed to cover one or two major subject areas. However, as you progress, it is often necessary to combine previous learning to accomplish new skills. A review of previous lessons may be necessary. Frequent visits to the Glossary may also be useful.在尝试回答自我评估问题之前，完成指定的阅读材料。仔细阅读，必要时重新阅读以理解。随意阅读可能会导致缺少支持主题的有用信息。作业旨在涵盖一个或两个主要学科领域。但是，随着您的进步，通常需要结合以前的学习来完成新技能。可能需要回顾以前的课程。经常访问词汇表也可能有用。3.Exercises 习题Exercises are included within each lesson to help you apply the lesson content. Some exercises may be more applicable to your workplace and background than others. You should review the answers to all exercises since the answers are very detailed. Answers to the exercises can be found at the end of each lesson. Your answers to these exercises are valuable study guides for the final examination.每节课都包含练习，以帮助您应用课程内容。有些练习可能比其他练习更适合您的工作场所和背景。您应该查看所有练习的答案，因为答案非常详细。练习的答案可以在每节课的末尾找到。您对这些练习的回答是期末考试的宝贵学习指南。4.Self-Assessment Quizzes 自我评估测验After completing the reading assignment, answer the self-assessment quizzes before continuing to the next lesson. Answers to the quizzes can be found at the end of the lesson. After passing all six lesson quizzes, you should be prepared for the final examination.完成阅读作业后，回答自我评估测验，然后继续下一课。测验的答案可以在课程结束时找到。通过所有六节课测验后，您应该为期末考试做好准备。
[*]Self-assessment quizzes are open book.
自我评估测验是开卷的。
[*]Unless otherwise noted, choose ALL CORRECT answers.
除非另有说明，否则请选择所有正确答案。
[*]Do not guess at the answer.

在继续下一课之前，您应该至少正确 70%。
5.Tips for Answering Questions回答问题的提示
[*]Carefully read the question.
仔细阅读问题。
Note that it may ask, “Which is CORRECT?” as well as “Which is NOT CORRECT?” or “Which is the EXCEPTION?”
请注意，它可能会问，“哪个是正确的？”以及“哪个是不正确的？”或“哪个是例外？”
[*]Read all the choices given.
阅读给出的所有选项。
One choice may be a correct statement, but another choice may be more nearly correct or complete for the question that is asked.
一个选项可能是一个正确的陈述，但对于所提出的问题，另一个选项可能更接近正确或完整。
6.Final Examination and Course Evaluation期末考试和课程评估We recommend that you thoroughly review the questions included with each lesson. There is no final exam.我们建议您仔细复习每节课中包含的问题。没有期末考试。
