Lesson details

When you get infected with a germ, you're meeting that germ at the end of its journey. But what if that journey could be stopped so the germ never gets to you to begin with? We call this journey 'the chain of infection', and in this lesson, Jack Crenshaw will explain the steps in the chain of infection and how you can break it to stop a germ from spreading.
