Mechanisms of HIV detection for people who acquire HIV through age 30. This figure includes all people in the model simulation who ever acquired HIV through age 30, regardless of the age of diagnosis. Status quo screening reflects existing patterns of HIV screening. More frequent screening strategies were performed in addition to Status quo screening. All more frequent screening strategies identified a substantial proportion of YMSM (90%–98%). 3-monthly and 6-monthly screening resulted in the lowest proportions undetected (0%–1%) and diagnosed via opportunistic infection (1%).
