In this deck, we'll explore the battle between your body and the microscopic invaders that cause disease. You'll learn about communicable diseases, the pathogens that cause them, and how they spread. We'll also cover your body's amazing defence systems, how vaccines provide immunity, and the important roles of antibiotics and painkillers.

Health is the state of physical and mental well-being. Diseases can disrupt this state. Some diseases, called communicable diseases, can be spread from person to person. These are caused by microorganisms called pathogens. There are four main types of pathogen you need to know: viruses, bacteria, protists, and fungi.
