Measure	Time frame
In the clinical setting, several new HIV diagnoses among PWID were identified at the study center over a five-year period (2021–2025). The aim of the study is to identify all new HIV diagnoses among PWID at the study center. Subsequently, molecular phylogenetic analyses of HIV sequences will be performed to investigate potential transmission links. The present study therefore seeks to analyze the clinical, epidemiological, and molecular characteristics of these cases.	—
