In this free course, Infection and immunity, you will be introduced to infectious diseases and to the biological agents that invade our bodies and cause them: pathogens. You will also learn about the immune system, the human body’s vital defence against pathogens. Along the way you will learn about the scientific method and how it has helped scientists understand pathogens and aid the prevention of infectious disease. But the challenge is ongoing. Pathogens are everywhere and come in all shapes and sizes. As you will see, the fight against infectious disease remains critical for global health today.
There are engaging videos and exciting animations to help you understand some more challenging concepts. The course is split into four sessions to help you structure your learning. Each session ends with a quiz so you can assess how well you're doing.
When you complete the course you'll receive a free statement of participation to help you to share your achievement.
This OpenLearn course is an adapted extract from the Open University course SDK100 Science and health: an evidence-based approach, which forms the entry module in our undergraduate degree in Health Sciences.
