One of the reasons for the large investment the scientific community has made in the study of social networks is their connection with the spread of disease. Diseases spread over networks of contacts between individuals: airborne diseases like influenza or tuberculosis are communicated when two people breathe the air in the same room; contagious diseases and parasites can be communicated when people touch; HIV and other sexually transmitted diseases are communicated when people have sex. The patterns of such contacts can be represented as networks and a good deal of effort has been devoted to empirical studies of these networks' structure. This chapter looks at the connections between network structure and disease dynamics and at mathematical theories that allow us to understand and predict the outcomes of epidemics. Exercises are provided at the end of the chapter.Less

This chapter begins with a discussion of the emergence and rapid global spread of AIDS. In 2013, 1.5 million people died of AIDS despite the existence of antiretrovirals. The majority of these deaths occurred in sub-Saharan Africa, where AIDS is the leading cause of death in about half the countries. In Europe and the United States twenty-seven thousand people died from AIDS in 2013, most of whom could have been saved if they had had access to early diagnosis and appropriate treatment. The remainder of the chapter covers how the number of people infected with HIV is estimated; generalized and concentrated epidemics; the diversification of epidemics; the factors that determine the spread HIV; and the achievements made in the global response to AIDS.Less
