Medical Geography Epidemic Local or regional dimensions, Often acute onset Distribution often depends on vector –Sleeping Sickness Vectored by tsetse fly Endemic in wildlife but kills Bos indicus/Bos taurus No ‘domestic’ cattle breeds on African savannah
8
Medical Geography Pandemic Spread is “worldwide” –Mosquito borne: Yellow Fever Malaria –DDT

Medical Geography Imminent Pandemic? – Spanish influenza 1918-19 H1N1: 20-50 million deaths worldwide – Avian influenza? H5N1
10
AIDS –Pandemic since 1990s –ARV drugs in developed countries e.g. AZT –80% of 37 million infected are in Africa –Shifted from equatorial belt to southern Africa Botswana, Namibia, Zimbabwe 25% of 15-49 population infected Life expectancy is declining Impact on labour force and economic development Population declines of 10-20% –Bubonic plague in Europe –Small pox among indigenous people of Americas MEDICAL GEOGRAPHY
