How does disease spread?
In module 2, students learn how infectious diseases are spread. Students identify key components of a chain of infection, assess the spread of an infectious agent, and design evidence-based prevention strategies to reduce disease spread. Students also learn what it takes to pursue a public health career as an infection prevention specialist.
This video will help students answer the question “How does disease spread?”
During this video, students will see how infection prevention specialists use information on the type of infectious agent, how it is spread, and common ways it exits and enters its hosts to create a chain of infection model. This information can then be used to identify appropriate prevention strategies to reduce the spread of the disease.
In this activity, students use think, pair, share, and concept mapping to create a possible chain of infection for NERD and brainstorm strategies to reduce the spread of disease.
This video illustrates how to teach this activity in a classroom setting. It demonstrates how teachers can prepare handouts and arrange classrooms for student learning and engagement.
An infection prevention specialist studies diseases and helps develop ways to detect, prevent, and control their spread.
