  • Climate Change and the Spread of Disease
    • Drought
      • Less than average rainfall for a prolonged period of time.
      • Malnutrition due to less water, less crops grown.
      • Increase in forest fires, creating respiratory diseases.
    • Monsoon
      • Intense and heavy rainfall.
      • Increase in humidity, more water, more water-borne diseases.
    • West Nile Virus
      • Uganda 1937, transmitted by the Cluex mosquito.
      • As it becomes warmer, it'll spread out of Africa into the Americas and Europe.
      • In 2012, 5500 cases in USA and 286 deaths. Texas was severely affected: higher temp = higher transmission.
    • Ticks
      • Climate change is responsible for the spread of Lyme disease. They thrive in warmer conditions.
      • Lyme disease is expanding northwards in the US, eventually will colonise in Canada.
    • Tsetse Fly
      • The Tsetse Fly spreads sleeping sickness and is endemic in 36 sub-Saharan countries.
      • It will likely spread to South Africa and they survive in temperatures 20.7C to 26.1C.
