Document Summary
Week 3 the impacts of time on populations and their health. Lecture 4 impacts of time on populations and their health. Latency: time lag between exposure and outcome (i. e. latent disease that is dormant; various types of diseases that lay dormant in our body) Examples: hiv infection: week 9 shows clinical latency (infected with hiv, but not showing symptoms), but in 7 years we will see the onset of symptoms and in 11 years into infection the individual will experience death. Can see latency through gradients (slopes) and dope response. Gradient = obvious pattern movement from high to low. I. e. relationship between continental regions and infant mortality rates; we see that developing countries have higher rates of infant mortality. Richest regions are experiencing a comparatively lower infant mortality rate (socioeconomic status and infant mortality relationship) Examples of time lag: the great fog of 1952 (london)
