Module 2 of 5
Core principles of disease prevention. Vaccines, hygiene, and community-level protective behaviors.
In eight minutes you'll learn how a few low-cost habits close the "prevention gap" that lets diarrhoea, malaria, and infections steal weeks of life from a community every rainy season.
It's Not a Disease Problem
1 / 5 · 2 minSamuel, primary school teacher in Kakamega, Western Kenya
Every rainy season, Samuel's school loses students for weeks to diarrhoeal disease, malaria, and respiratory infections. He has started to believe it is simply 'how things are when the rains come.'
His neighbour Beatrice, a community health worker, disagrees. She tracked which households got sick most. Almost always, they were the same ones: uncovered water storage, no latrines, children who missed vaccines, no handwashing before eating.
Samuel's school does not have a disease problem. It has a prevention gap. This lesson is about closing it.

This content is for learning purposes only. It is not medical advice, diagnosis, or treatment. Health decisions — especially about pregnancy, child health, medications, and mental health — should be made with a qualified healthcare professional. In an emergency, seek care immediately.

Let's start with the simplest idea — stopping disease before it ever begins.
