Subject: Geography
Lesson Topic: Influenza (flu) as an example of a viral disease
Learning Objective/s:
  • Describe the structure of influenza viruses and how it relates to transmission.
  • Explain the main transmission pathways (droplets, aerosols, fomites) and factors influencing spread.
  • Analyse epidemiological concepts such as R₀ and geographic patterns of seasonal influenza.
  • Evaluate the health, economic and social impacts of influenza outbreaks.
  • Propose appropriate control and prevention strategies for different geographic contexts.
Materials Needed:
  • Projector and screen for slides/diagrams
  • Printed handout summarising virus structure and transmission
  • Interactive world map of influenza incidence (digital or printed)
  • Whiteboard and markers
  • Sticky notes for group brainstorming
  • Laptop with internet access for video clip on the 2009 H1N1 pandemic
 Introduction:
Begin with a short news clip showing crowded airport terminals during flu season to highlight the relevance of disease spread. Ask students what they already know about how viruses travel between people. Explain that by the end of the lesson they will be able to map transmission routes, calculate basic reproduction numbers and suggest geographic‑specific prevention measures.
Lesson Structure:
  1. Do‑now (5'): Students list ways they think flu spreads and post ideas on sticky notes.
  2. Mini‑lecture (10'): Overview of influenza virus structure and classification using slides.
  3. Interactive activity (12'): Groups create a flowchart of the infection cycle and transmission pathways on large paper.
  4. Data analysis (10'): Examine a world map of seasonal influenza cases; calculate example R₀ values and discuss climate influence.
  5. Case study discussion (8'): Review the 2009 H1N1 pandemic and identify lessons for control measures.
  6. Check for understanding (5'): Quick Kahoot quiz on key concepts and an exit‑ticket question.
Conclusion:
Summarise how virus structure, transmission routes and R₀ determine the geographic spread and impact of influenza. Ask students to write one key prevention action they would recommend for their local community as an exit ticket. For homework, students will research the current seasonal flu vaccine composition and prepare a short briefing for the next class.
