16 cards

  1. How does the WHO define health?

    A state of complete physical, mental and social well-being, not just the absence of disease.

  2. What is a communicable disease?

    A disease caused by a pathogen that can be spread.

  3. Give two examples of communicable diseases.

    Cholera, tuberculosis, malaria or HIV.

  4. What is a non-communicable disease?

    A disease that is not caused by a pathogen and cannot be passed on.

  5. Give two examples of non-communicable diseases.

    Cancer, heart disease, diabetes or cystic fibrosis.

  6. What is a pathogen?

    A microorganism that causes disease.

  7. Name four types of pathogen.

    Viruses, bacteria, fungi and protists.

  8. Why does HIV increase the risk of TB?

    It destroys white blood cells, so the immune system is weaker.

  9. How can a communicable disease cause a non-communicable disease?

    HPV infection can lead to cervical cancer.

  10. How does poor nutrition affect susceptibility to disease?

    It weakens the immune system.

  11. What is a positive correlation?

    As one variable increases, the other also increases.

  12. Does correlation prove cause?

    No. Other factors might affect both variables.

  13. Give two factors that affect health.

    Diet, stress, poverty, genes, or exposure to pathogens.

  14. Can mental health affect physical health?

    Yes. Stress can weaken the immune system.

  15. Is a person with no disease but who is lonely fully healthy, according to the WHO?

    No. Social well-being is also needed.

  16. Common mistake about non-communicable diseases?

    Saying they are caused by pathogens. They are not.
