  • The Geography of Disease Part One
    • Incidence of disease is affect by environmental factors:
      • Climate
        • Extreme Events
          • Flooding - sewage overflow
            • Contaminates water supply
              • Low rainfall = WV become concentrated
        • Temperature
          • V can only survive over a certain temp threshold
            • Many V occur in tropical climates
              • ^ temps ^ likelihood of FBV
        • Seasonality
          • Arctic areas = low light
            • Affects mental health
              • SAD
        • Precipitation
          • Vectors (V) need water to survive
            • Higher than average can cause growth in pops of V
        • Sunlgiht
          • Lack = Vitamin D deficiency
            • Bone loss, Kidney disease
              • Too much = Skin cancer
    • NGOs
      • Small scale impacts
        • Rely on donations
      • Promote global health research & healthcare to LDC
        • HC = poor and remote communities with poor infrastructure
      • Non-profit groups - independent from g
        • Often charities
    • Poor Water Quality
      • Examples
        • Cholera
          • Bacterial infection, diarrhoea and dehydration
        • Hepatitis A
          • Liver disease, leads to fever and nausea
      • Chemical Toxins
        • Heavy metals released into water
      • By disease-causing organisms and chemical toxins
        • MO live in water that is contaminated with faeces
          • Spread - Drinking or bathing
            • 3.4 million deaths
    • International Organisations are important in the fight against disease
    • Poor Air Quality
      • Urban Areas
        • Most likely to be affected
          • 1.2 million deaths per year
      • Burning Fossil Fuels
        • Poisonous gases
          • Respiratory problems & CVD
      • Indoor Air Quality
        • No proper ventilation
          • indoor wood burners
            • Respiratory problems
    • QUESTIONS
      • 3. One way that an international agency acts to promote health
      • 2. Name one disease caused by poor water quality
      • 4. Assess the extent to which the incidence of ID is affect by environmental variables
      • 1. Give one way the climate affects disease
