Define risk factor and list at least five risk factors that increase a person’s chance of catching a communicable disease.
Explain how each risk factor (such as poor sanitation, overcrowding, unsafe water, poor nutrition, and lack of vaccination) contributes to the spread of diseases like hepatitis, HIV, and measles.
Analyse a given scenario and identify the risk factors present, explaining how they could lead to disease transmission.
Create a simple awareness message (poster, jingle, or short talk) that educates their school or community about risk factors and how to reduce them.
