| Lesson Topic: Transmission, threat to populations and distribution: how cholera is transmitted and factors influencing its spread |
Learning Objective/s:
- Describe the main transmission routes of cholera.
- Identify environmental, social and economic factors that influence cholera spread.
- Analyse the health, socio‑economic and developmental impacts of cholera outbreaks.
- Evaluate strategies for managing and reducing cholera risk.
|
Materials Needed:
- Projector and screen
- Printed handouts (cholera case study & factor table)
- World map or GIS printout showing cholera hotspots
- Worksheet for factor analysis
- Video clip on water sanitation interventions
- Markers, sticky notes, and pens
- Internet access for an interactive quiz (Kahoot)
|
Introduction:
Begin with a brief news headline about a recent cholera outbreak to capture interest. Ask students what they already know about how diseases spread and link this to previous lessons on pathogens. Explain that by the end of the lesson they will be able to trace cholera’s transmission pathways and evaluate the factors that shape its distribution.
|
Lesson Structure:
- Do‑now (5'): Students write as many disease transmission routes as they can on sticky notes and post them on the board.
- Mini‑lecture (10'): Slide presentation covering cholera biology, the fecal‑oral route and basic R₀ concept.
- Interactive map activity (12'): Using the world map, groups pinpoint cholera hotspots and discuss related environmental and social conditions.
- Group analysis (15'): Examine the factor table, create a cause‑effect diagram linking water quality, poverty, governance, etc., to disease spread.
- Case‑study discussion (10'): Review the Bangladesh water‑treatment kiosk example and assess why it succeeded.
- Quick quiz (5'): Kahoot quiz to check understanding of transmission routes and influencing factors.
- Exit ticket (3'): Each pupil writes one practical action that could reduce cholera risk in their local community.
|
Conclusion:
Summarise how cholera’s spread is driven by interlinked environmental, social and economic factors and how targeted interventions can break the transmission cycle. Collect exit tickets as a retrieval check and assign homework: research a local water‑safety initiative and prepare a short report outlining its potential impact on cholera risk.
