In 2024, five years later, 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%. 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.
