processes
Epidemiological Transition
PATHOGEN INDUCED INFECTIONS

CHRONIC MAN MADE DISEASE (pollution)

energy)
- Epidemiological transitions:
1. Shift from foraging to primary food prod., domestication of
plants/animals prevalence of infectious disease, increase in pop
size and density, sedentarism, social stratification creates shift in
disease ecology
2. Decline in infectious disease and rise of chronic man mad disease
(controversial because third world still lives with infectious
disease)

infectious diseases, resistant to antibiotics, reemergence of novel
diseases

- Heirloom pathogens: lice, pinworm, protozoa,bacteria (parasites shared
with early hominids, remained after speciation)
- Zoonatic diseases from hunter-gatherers because of frequent movement and
egalatarian nature
