Subject: Geography
Lesson Topic: Detailed specific example of the strategies used by one country to prevent and control cholera
Learning Objective/s:
  • Describe the main components of Bangladesh’s cholera prevention and control strategy.
  • Explain how WASH, vaccination, surveillance, community engagement, and infrastructure reduce cholera transmission.
  • Analyse impact‑assessment data to evaluate the effectiveness of each strategy.
  • Apply basic SIR model concepts to illustrate how interventions modify transmission and recovery rates.
  • Propose an adapted action plan for another low‑resource country based on Bangladesh’s example.
Materials Needed:
  • Projector and screen for slides/diagrams
  • Printed case‑study handout on Bangladesh’s cholera strategies
  • Map of Bangladesh highlighting flood‑prone districts
  • Worksheet with impact‑assessment data tables
  • Markers and flip chart for group brainstorming
  • Internet access for a short video on WASH interventions
 Introduction:
Begin with a striking fact: Bangladesh records up to 200,000 cholera cases each year, many linked to seasonal floods. Ask students what they know about water‑borne disease control and connect it to prior lessons on public‑health geography. Explain that today they will examine a real‑world, multi‑sectoral response and identify the key success criteria: understanding each strategy, interpreting impact data, and suggesting adaptations for other contexts.
Lesson Structure:
  1. Do‑now (5'): Students write on a sticky note “What factors make cholera outbreaks likely in flood‑prone areas?” and share responses.
  2. Mini‑lecture (10'): Overview of Bangladesh’s cholera burden and the five strategy pillars, using map and diagram.
  3. Data analysis activity (15'): In pairs, examine the impact table, calculate percentage reductions, and discuss which strategy shows the greatest effect.
  4. SIR model demonstration (10'): Show how vaccination lowers β and sanitation raises γ, linking to earlier concepts.
  5. Group planning task (15'): Each group adapts one strategy for a different low‑income country, recording ideas on a worksheet.
  6. Gallery walk & feedback (5'): Groups post plans; classmates leave one comment; teacher summarizes key insights.
Conclusion:
Summarise how Bangladesh’s integrated approach achieved measurable declines in cholera incidence and why each component matters. Have students write an exit ticket stating which strategy they found most impactful and why. Assign homework to research a current cholera outbreak and suggest one additional intervention.
