This program examines modern day epidemics, using three case studies from the late 20th and early 21st centuries - SARS, HIV-AIDS, and influenza. Firstly, SARS took the world by surprise in early 2003, and was particularly prevalent in Hong Kong and the south of China. The program looks at the response by authorities in the area, and outlines how the Australian government handled fears. Secondly, HIV-AIDS exists in epidemic proportions in southern Africa, and the program includes reports from ABC journalists from South Africa and Kenya. The third epidemic, influenza has been around for more than a century and has claimed more human lives than any other disease. Experts predict that another epidemic could hit at any minute and the program explores how Australia is preparing itself. Extracts of ABC current affairs programs were used in the making of this program.
