Subject: Geography
Lesson Topic: the potential risks of cholera spread following disaster events
Learning Objective/s:
  • Describe the main transmission routes of cholera and how disasters amplify them.
  • Analyse how different disaster types (flood, earthquake, cyclone) increase cholera risk.
  • Evaluate immediate public‑health interventions to prevent and control cholera outbreaks after a disaster.
  • Interpret a risk‑assessment matrix to prioritise response actions.
  • Apply knowledge from a real case (Haiti 2010) to propose a short‑term response plan.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed handout with risk‑assessment matrix
  • Case‑study worksheet (Haiti earthquake)
  • Images of portable water‑testing kits (for discussion)
  • WHO cholera fact sheet (digital copy)
  • Markers and flip‑chart paper
 Introduction:
Begin with a striking image of a flood‑damaged community lacking clean water and ask students what health threats they anticipate. Recall prior learning on water‑borne diseases and the role of sanitation. Explain that by the end of the lesson they will be able to identify disaster‑related cholera risks and outline a rapid response plan.
Lesson Structure:
  1. Do‑now (5') – quick mind‑map of known water‑borne diseases.
  2. Mini‑lecture (10') – overview of cholera biology, symptoms, and transmission routes.
  3. Disaster risk analysis (12') – groups examine the risk‑assessment matrix and link specific disaster impacts to cholera transmission pathways.
  4. Case‑study investigation (15') – small groups work through the Haiti 2010 worksheet, identifying key failures and successful interventions.
  5. Response planning activity (10') – each group creates a five‑point short‑term response checklist and shares it with the class.
  6. Check for understanding (8') – exit‑ticket: one sentence summarising the most critical factor that raises cholera risk after a disaster.
Conclusion:
Summarise how disaster‑induced disruptions to water and sanitation elevate cholera transmission and why rapid assessment is vital. Collect exit tickets to gauge understanding, and assign homework to draft a brief response plan for a hypothetical flood scenario.
