HIV Underdiagnosed

JAMA. 2019;321(18):1760. doi:10.1001/jama.2019.4922

About 80% of new HIV cases in 2016 stemmed from people who didn’t know they had HIV or were not receiving treatment, according to a CDC Vital Signs report.

The data are based on the CDC’s Progression and Transmission of HIV (PATH 2.0) model. Patients taking antiretroviral therapies and achieving viral suppression didn’t contribute to the 38 700 new infections, while those aware of their HIV infection but not in regular care contributed to the greatest proportion of new cases at 42.6%. Those unaware of infection contributed to 37.6%, and those receiving treatment but not virally suppressed contributed to 19.8%.
