Abstract Summary

San Francisco’s community viral load (CVL)—the average HIV viral load across all HIV-positive residents—dropped significantly from 2004-2008, coinciding with a 46% decrease in new HIV diagnoses (798 to 434 cases). This strong correlation suggests that widespread antiretroviral therapy and viral suppression can reduce HIV transmission at the population level, supporting CVL as a valuable surveillance tool.

Why Brain? 🧠

San Francisco data shows population-wide viral suppression through increased HIV testing and treatment correlates with 46% reduction in new infections, supporting antiretroviral therapy as prevention strategy.
