Document Summary
Each caused by a single microbe: one germ one disease , thought they could stop it if they found the one germ. No way to: avoid exposure, prevent infection, cure. Eventually controlled by: public health advances: Safer food, waste, waste management, working conditions: medical advances. Develop slowly, persist, recur over long time period, come and go. Often can be controlled but not cured. Multiple determinants include: specific(lifestyle) behavioral/psychosocial factors. Smoking, diet, exercise, stress -> stress: not caused by a single germ. Greater life expectancy (from 40 to 70 years) Hiv/aids: infectious condition, emerged late in the 1900s. Exposure to virus difficult to prevent through either public health or biomedical intervention: cant enforce safe sex. Has evolved into a more chronic condition from an acute infectious condition. Chronic conditions that appear to reflect infections: infectious diseases can lead to chronic conditions. Does the changing health pattern reflect changes in human nature: can it explain changes in disease patterns; obesity epidemic.
