Document Summary
98% of human history as foragers: paleolithic diet lots of vegetables, low in fat, sodium, and carbohydrates, little or no diseases of affluence , typically died from trauma or infection. 1st epidemiological transition (~10,000 years ago: food production altered human relationships with environment, archaeological evidence 10,000 to 12,000 years ago. Impact of agriculture (~10,000 years ago: change in ways humans interact with environment, major changes in diet, changes in demography and economy, sedentary communities. Consequences of agriculture: new opportunities for zoonoses infectious disease acquired from animals, sedentism garbage/human waste accumulate, high population densities favour herd diseases (person person) New opportunities for zoonoses: zoonoses = infectious diseases acquired from animals. 2nd epidemiological transition industrialization (~200-300 years ago) Increased longevity: chronic and degenerative diseases increase, biomedical technology and science (i. e. vaccinations, continued population growth and urbanization. 3rd epidemiological transition (~25-30 years ago: environmental degradation and ecological change brings humans into contact with pathogens.
