Leveraging Phylogenetics to Understand HIV Transmission and Partner Notification Networks

Pathogen genetic information can be used to infer transmission clusters.  In this figure, social contacts and sexual partnerships elicited during HIV contact tracing are compared to HIV transmission clusters constructed from HIV gene sequences.  The goal is to improve public health contact tracing, find more HIV cases, and get more people into care.  Read more at:  J Acquir Immune Defic Syndr (2018), 78(4), 367-75. doi:10.1097/QAI.0000000000001695

Social Networks And Health: It’s Who You Know

Every office has experienced it. One person contracts a cold, and before you know it the entire group is coughing and reaching for the tissues. Our social connections have incredible implications for our health, and not just because they shape the spread of communicable diseases like the common cold, the flu or even HIV.


Sparked by the confluence of a rapid rise in network techniques across the social and physical sciences, the Duke Network Analysis Center seeks to crystallize the latent talent in this area at Duke and around the triangle to build a world-premier source for cutting edge network studies. The rise of network science over the last 10 to 15 years is predicated on building scientific insight by modeling the complex patterns of connections that link primary elements to each other. The range of such work is exceedingly broad, since the unifying network abstraction is virtually content free. Thus, social network studies add relational context to our understandings of human behavior in areas as diverse as health, culture, organizations, science or politics. Similar tools are used to great advantage in biology, physics, and ecology to name just a few.
