This study brings together health-care professionals and scholars from a variety of disciplines who seek to understand, and prevent, the transmission of HIV. The biological and social factors concerned with the spread and impact of HIV/AIDS has resulted in dedicated research from each of the disciplines and provided unique insights into the disease. By assembling their insights in one multidisciplinary volume, this book provides a more complete picture of the complex disease, and demonstrates why preventing the spread of HIV will require interdisciplinary collaboration.
