Objective 1: Describe the variations in health as reflected by changes in life
expectancy at national and global scales since 1950. Explain the patterns and
trends in terms of differences in income and lifestyle.
Objective 2: Evaluate life expectancy, infant mortality rate (IMR) and child
mortality, HALE (health-adjusted life expectancy), calorie intake, access to safe
water and access to health services as indicators of health.
Objective 3: Discuss the geographic factors that determine the relative emphasis placed by policy-makers, in one country or region, on prevention as opposed to treatment of disease.
In this section we will study South Africa and their approach to HIV/AIDS treatment. We will gain an understanding of the disease and then focus on the strategies employed to prevent the spread of the disease.
