The figure displays the distribution of HCV status disclosure within injecting partnerships (N=131), categorized by self-reported partnership HCV serostatus: concordant negative (-/-), discordant (+/-), concordant positive (+/+), and missing. Disclosure is grouped into three categories: mutual disclosure (both partners disclosed their status), one-way disclosure (only one partner disclosed), and no disclosure (neither partner disclosed). Mutual disclosure was highest in concordant positive partnerships (41.7%) and lowest in discordant partnerships (16.7%). In contrast, no disclosure was most common in concordant negative partnerships (50.0%) and least common in concordant positive partnerships (10.7%). These findings highlight how disclosure behaviors vary by partnership HCV status, with higher mutual disclosure occurring when both partners self-report a positive HCV status
