New NIH Grant to Identify HIV MicroEpidemics in Lima, Peru

A new CFAR Supplement grant from the NIH will examine spatial-genetic clustering of HIV infections among males who have sex with other males (MSM) in Lima, Peru.

The study will make use of state of the art genetic markers to identify recent infections within the MSM population — so-called “HIV MicroEpidemics”.  Spatial analyses will be conducted to identify neighborhoods and social venues — the places that are most associated with these MicroEpidemics.  And, the study will be able to assess the role that certain risk factors, such numbers of sexual partners and alcohol and drug use, play in MicroEpidemic transmission.

Dr. Edmund Seto will serve as the new study’s director.  His research group in the Department of Environmental & Occupational Health Sciences at the University of Washington will contribute to the spatial-genetic analyses for this study. The research builds off the Center for AIDS Research (CFAR) at the University of Washington led by King Holmes,  the ongoing ¿Sabes? research study collaboration between Ann Duerr’s group at Fred Hutchinson Cancer Research Center at Manual Villaran at Impacta in Peru, as well as work on HIV genetics by Joshua Herbeck in the Department of Global Health at the University of Washington.
