About the talk

Sexually transmitted infections (STI) spread through networks of susceptible people, where the people form nodes in the network, and the links are sexual intercourse. Data on sex partners of people are available from network studies, and from public health units which co-ordinate partner notification, in which sex partners exposed to people with STI are notified of their exposures, tested and treated. Key features of networks in which STI flourish include homogeneity; where many of the members share common characteristics; but also require a certain amount of heterogeneity, whether it is in ethnic origin, age, or geography. We explore the nature of long distance links, where sex partners reside far away from each other and the impact that has on STI transmission. Last, we review the important role of social venues or “pick-up” joints in sexual networks; and their implications for prevention programs.
