This research combined information from 21 different studies conducted across sub-Saharan Africa. The group included 8,476 transgender women and 24,102 cisgender men who have sex with men. The main goal was to compare how common HIV was in these two groups and to see how their rates related to each other and the general population.
The analysis showed that the median HIV prevalence was 23.5% among transgender women, while it was 16.2% among cisgender men who have sex with men. This means HIV was 50% more common in the transgender women group. The rates for transgender women varied widely, ranging from 11.5% to 39.8% across the different studies included.
Researchers also looked at how these rates moved together. They found a strong link between HIV rates in transgender women and cisgender men who have sex with men. In contrast, the link between transgender women and the total population was very weak. No safety issues were reported because the study looked at infection rates, not medication side effects.
Readers should understand that these numbers show a link, not a cause. The data comes from surveys about risk behaviors and infection, not from testing new treatments. These findings highlight the need for HIV programs to specifically address the higher vulnerability faced by transgender women in this region.
