This exam tips covers Disease Prevention Strategies within Pathogens and Disease Transmission for GCSE Biology. Types of pathogens, how diseases spread, transmission methods, and prevention strategies It is section 9 of 19 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
Disease Prevention Strategies
Personal Hygiene
- Hand washing: Soap removes pathogens and breaks down protective membranes
- Respiratory etiquette: Cover coughs and sneezes to prevent airborne transmission
- Food safety: Cook food thoroughly, wash fruits and vegetables
- Personal items: Don't share towels, razors, or other personal items
Medical Interventions
- Vaccination: Trains immune system to recognize specific pathogens
- Antibiotics: Kill bacteria but not viruses, fungi, or protists
- Antifungal medications: Target fungal infections
- Isolation: Separate infected individuals to prevent spread
Environmental Control
- Vector control: Eliminate breeding sites (standing water for mosquitoes)
- Sanitation: Clean water supplies and sewage treatment
- Food safety systems: Hygiene standards in food preparation
- Quarantine: Restrict movement of potentially infected individuals
