CThe claim is incorrect because antibiotics are too expensive
DThe claim is correct because all illnesses are caused by bacteria

Review & Reflect

✓ I can explain...

  • The difference between infectious and non-infectious diseases with examples
  • How pathogens cause disease and how they spread
  • The body's three lines of defence and how they work together
  • How vaccination creates immunity and why herd immunity matters
  • How antimicrobial resistance develops through natural selection
  • The role of public health in preventing and controlling disease

⚠ I need to review...

  • The specific roles of B cells, T cells, and antibodies
  • The difference between active and passive immunity
  • How to design fair tests and case-control studies
  • The social determinants of health and Closing the Gap
  • Connecting disease concepts to Australian and global contexts
