Estimating the number of infected and infectious PLWH in China. A, Total number of people infected with HIV (ie, diagnosed and undiagnosed) is estimated periodically via a joint assessment process performed by NCAIDS/China CDC, UNAIDS, and WHO. Numbers of diagnosed PLWH and virally suppressed PLWH are obtained from case reporting data in CRIMS. Difference between the estimated number of people infected and the actual number of people diagnosed equals the estimated number of undiagnosed PLWH (ie, those who are infected but remain unaware of their status). Likewise, difference between the number of diagnosed PLWH and the number of virally suppressed PLWH equals the number of unsuppressed PLWH. B, Summed together, the undiagnosed and the unsuppressed equal an estimated number of PLWH who are infectious and capable of transmitting their HIV infection on to others.
