DiagramUnit: Infection & ResponseGCSE

Painted 2x2 grid showing four routes of disease transmission: airborne (person sneezing droplets toward another), water (contaminated water containing pathogens), contact (hand touching contaminated surface then face), and vector (mosquito biting skin and transferring pathogens). Each route shown with distinct background tint.

This diagram covers Disease Transmission Methods within Pathogens and Disease Transmission for GCSE Biology. Types of pathogens, how diseases spread, transmission methods, and prevention strategies It is section 4 of 19 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
