Transmission Dynamics Along the Continuum of HIV Care

Updated CDC analysis reinforces the association between a robust cascade of HIV care and lower transmission risk.

To prioritize HIV prevention efforts, the CDC recently updated their transmission model using the National HIV Surveillance System for 2019 (data on 35,100 new infections and status along the HIV continuum of care). The model assumes that the HIV transmission rate for persons living with HIV (PWH) with suppressed HIV levels is zero. Baxter et al. analyzed these U.S. data by ethnic group, gender, transmission category, and age to determine the HIV transmission rate for each subset of PWH.

The estimated overall HIV transmission rate was 2.9 infections per100 person-years, a 26% decrease that was consistent with the growing percentage of PWH suppressed on ART (from 45% to 57%). The highest transmission rates on the continuum were in PWH with ac…
