Networks and HIV: The Structure of Transmission

Martina Morris

The dramatic variations in HIV spread among different populations of the world has led to much research on the causal mechanisms of transmission. Some focus on bio-medical factors, such as the enhanced infectivity caused by other sexually transmitted diseases, others focus on the sexual behavior and network patterns that spread the pathogen. This talk will explore several examples from the network paradigm, which data from the United States, Uganda, and Thailand. The combination of network survey data and simulation have lead to some interesting and unexpected findings that challenge the traditional individualistic focus of medical research and demonstrate the utility of a population systems perspective.
