In 2024 the data show that people who inject drugs are still being left behind in the response. In 2022, the global median HIV prevalence among people who inject drugs was 5% across 50 reporting countries, seven times higher than among the rest of the adult population (aged 15–49 years). This figure hides significant geographical and population-based disparities. Among reporting countries, HIV prevalence ranged from 0% to 51% (2). Among the 16 countries with gender disaggregated data, the reported median HIV prevalence among men who inject drugs was 9%, while it was nearly double (15%) among women who inject drugs (2).
