- This point belongs to Health, disease and the development of medicines, especially Common Infectious Diseases.
- You need to be able to give a clear account of some common infections, covering: a cholera (bacteria) causes diarrhoea b tuberculosis (bacteria) causes lung damage c Chalara ash dieback (fungi) causes leaf loss and bark lesions d malaria (protists) causes damage to blood and liver e HIV (virus) destroys white blood cells, leading to the onset of AIDS fB stomach ulcers resulting from Helicobacter (bacteria) gB Ebola (virus) causes haemorrhagic fever.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

- Give a clear account of the difference between communicable and non-communicable diseases.
Communicable vs. Non-Communicable Diseases
- Give reasons why the presence of one disease can lead to a higher susceptibility to other diseases.
Impact of Existing Diseases on Subsequent Infections
- Give a clear account of a pathogen as a disease-causing organism, covering viruses, bacteria, fungi and protists.
Pathogens: Types and Disease Mechanisms
- Build an explanation of the way pathogens are spread and how this spread may be reduced or prevented, covering: a cholera (bacteria) – water b tuberculosis (bacteria) – airborne c Chalara ash dieback (fungi) – airborne d malaria (protists) – animal vectors eB stomach ulcers resulting from Helicobacter (bacteria) – oral transmission fB Ebola (virus) – body fluids.
Pathogen Transmission and Prevention
- Give a clear account of the lifecycle of a virus, covering lysogenic and lytic pathways.
