SOCIOL 44 Lecture Notes - Lecture 10: Sub-Saharan Africa, Epidemiological Transition, Lead Poisoning
Document Summary
Epidemiological transition: decline in mortality over time, changes in causes of death, major camps on mortality decline. End of epidemics, crisis mortality, and famine: major causes of death: ue, phenomena, small pox. Life expectancy 20-40 yrs: half of babies die before age 5. Nutrition: caused people to be more likely to survive a disease, middle ages nutrition became really good and was better than the industrial age. Early cities had a high mortality rate: crowding spreads disease faster, no proper sewage waste area. Sub leasing places to live: cities were dirty and lots of environmental toxins were present. Lead was very present in the water because of lead pipes, but that caused a lot of lead poisoning. Hygiene: germ theory-idea that you can have a virus or bacteria that cant be seen that causes disease, washing of hands. Antibiotics: world war 2-1960, resistance rising, over usage of antibiotics in people and animals.
