CAIE IGCSE Biology 10.1.5 Controlling disease spread
Practise explaining how hygiene, clean water, waste disposal and sewage treatment reduce pathogen spread in disease-control contexts.
How this is tested
- suggest hygiene, food preparation and clean-water advice to reduce diarrhoea spread
- explain how sewage treatment removes or kills pathogens before water reaches people
- interpret disease or hospital-admission data to link interventions with reduced cases
