Specific Disease Examples
| Pathogen Type | Disease | Transmission | Prevention |
|---|---|---|---|
| Bacteria | Tuberculosis (TB) | Airborne droplets | Vaccination, isolation, masks |
| Bacteria | Food poisoning (Salmonella) | Contaminated food | Cook food thoroughly, hygiene |
| Bacteria | Gonorrhoea (Neisseria gonorrhoeae) | Sexual contact (direct transmission of bacteria) | Barrier methods (condoms), screening, antibiotics (resistance increasing) |
| Virus | Measles | Airborne droplets | MMR vaccination |
| Virus | HIV/AIDS | Bodily fluids | Safe sex, sterile needles |
| Fungus | Athlete's foot | Direct contact, contaminated surfaces | Keep feet dry, don't share shoes |
| Fungus (plant) | Chalara ash dieback (Hymenoscyphus fraxineus) | Wind-borne spores; movement of infected nursery stock | Destroy infected trees; restrict movement of nursery stock; no cure |
| Protist | Malaria | Mosquito vector | Mosquito nets, destroy breeding sites |
