  • Disease Dilemmas
    • Diffusion
      • Expansion Diffusion
        • Spreads outwards from the source - people remain infected as it spreads
      • Relocation Diffusion
        • Rarest of all 4 - when a disease is carried across barriers away from its origin
      • Contagious  Diffusion
        • Spread of disease by direct/indirect contact
      • Barriers to Diffusion
        • Socio-economic
          • Quarantine
          • Mass vaccinations
          • Curfews
          • Protective clothing
          • Border Checks
          • Cancel big events

    • Torsten Hägerstrand's diffusion model
      • Concept 1 - The neighbourhood Effect
        • Possible contact between carrier and non-carrier is determined by the number of people living in a 5x5 area and their living distance
        • The closer people live the more likely the diffusion will take place
        • The greater the population density the more likely the diffusion will be
      • Concept 2- The spatial Logistic Curve
        • The number of people infected by an epidemic follows an S curve
        • There's a slow start to infection process
        • As more of the susceptible population are infected the rate of diffusion accelerates rapidly
        • The most susceptible people are old people and children
      • Concept 3: Physical Barriers
        • Progress and diffusion of a disease may be interrupted by physical barriers
        • 2014 ebola outbreak was prevented by physical barriers
          • The Sahara Desert
          • The Atlantic Ocean
          • The Central African Rainforest
