Subject: Geography
Lesson Topic: global distribution and spatial variation of cholera
Learning Objective/s:
  • Describe the environmental and socio‑economic drivers influencing the global distribution of cholera.
  • Analyse spatial patterns of cholera incidence within regions using GIS concepts.
  • Explain how climate variability and WASH infrastructure affect outbreak risk.
  • Evaluate control and prevention strategies, including vaccination and surveillance.
Materials Needed:
  • Projector and screen
  • World map or digital GIS layers showing water bodies and population density
  • Handout of the cholera incidence table (regions, drivers, outbreaks)
  • Worksheets for spatial analysis and case‑study questions
  • Laptop with GIS software (e.g., QGIS)
  • Printed diagram of endemic zones and recent hotspots
  • Markers and coloured pencils
 Introduction:
Recent headlines about cholera outbreaks in Yemen and Haiti highlight the ongoing public‑health threat. Begin by asking students what factors they think make some areas more vulnerable than others, linking to prior lessons on disease transmission. Explain that today they will identify those drivers, map spatial patterns, and assess how geography informs prevention.
Lesson Structure:
  1. Do‑now (5'): Students list possible drivers of cholera spread on sticky notes.
  2. Mini‑lecture (10'): Overview of cholera transmission, global distribution and key drivers using a world map.
  3. Data analysis activity (15'): In groups, plot the provided incidence data on a blank map, highlight hotspots and discuss regional differences.
  4. GIS demonstration (10'): Show how to layer water bodies, population density and case locations to reveal spatial patterns.
  5. Case‑study comparison (10'): Compare East‑Central Africa with South‑Asia, focusing on urban vs. rural dynamics and climatic influences.
  6. Formative check (5'): Quick Kahoot/exit‑ticket quiz on the main concepts.
Conclusion:
Recap the main drivers of cholera distribution and how GIS can expose vulnerability hotspots. Students complete an exit ticket summarising one preventive measure they consider most effective. For homework, each learner researches a recent cholera outbreak and writes a brief report linking the observed pattern to environmental and socio‑economic factors.
