Lesson Plan

• Describe the bacteriology and transmission pathways of cholera.
• Explain how environmental and social factors influence cholera spread.
• Analyse the health, economic and social impacts of cholera outbreaks.
• Evaluate control measures and the role of GIS in managing cholera risks.
• Apply geographic concepts to assess cholera risk in a given locality.

• Projector and screen
• Printed handout with the case‑study table
• GIS software demo or printed map sheets
• Diagram of the cholera transmission cycle
• Worksheet with scenario questions
• Whiteboard and markers

Begin with a brief news clip about a recent cholera outbreak to capture interest. Ask students to recall other water‑borne diseases they have studied and discuss why geography matters in disease spread. Explain that by the end of the lesson they will be able to identify key drivers, impacts and geographic solutions for cholera.

1. Do‑now (5'): Students list water‑borne diseases they know; share responses (activate prior knowledge).
2. Mini‑lecture (10'): Present key concepts of pathogens, focus on cholera etiology and transmission using slides and the transmission diagram.
3. Case‑study analysis (15'): In small groups, examine the Haiti, Yemen and Bangladesh data table; identify environmental and social drivers for each outbreak.
4. GIS mapping activity (10'): Demonstrate how GIS can map outbreak hotspots; groups plot the case‑study locations and discuss spatial patterns.
5. Control measures discussion (10'): Whole‑class brainstorm of water, sanitation, education and vaccination interventions; link each to geographic planning.
6. Exit ticket (5'): Each student writes one way geography can reduce cholera risk in their community.

Recap the main drivers of cholera spread and the geographic tools used to manage outbreaks. Collect exit tickets to gauge understanding, and assign a short homework: research a local water‑sanitation issue and propose a GIS‑based intervention to mitigate cholera risk.
