Proportion of people living with HIV (PLHIV) and those transmitting HIV who were unaware of their HIV-positive status, and their antiretroviral therapy (ART) status. The solid line represents the mean of 100 simulations and the shaded band represents the 90% credible interval. Over 2000–2019, the proportion of PLHIV unaware of their status decreased from 17 to 4%, while the equivalent proportion among those transmitting HIV varied between 41 and 56%. The proportion of PLHIV who had never been on ART decreased from 38 to 5%, while the proportion who had never been on ART at the time of transmitting HIV decreased from 85 to 58%
