Gassowski M, et al. - Researchers investigated how detention experience is linked with hepatitis C virus (HCV) status. Further, they determined the part played by length and frequency of detention and if an observed increase in risk could be explained by risk behaviors practiced in detention. They performed a sero-behavioral, cross-sectional survey utilizing respondent-driven sampling with 1,998 current drug injectors (who injected in the previous 12 months) in eight German cities during the years 2011–2014. Among these, no detention experience was reported in 19.9%, short and rare experience (≤3.5 years in total, ≤3 times) in 28.6%, short but frequent experience in 12.1%, long but rare experience in 7.1%, and long and frequent experience in 32.4%. findings revealed a higher risk of HCV in drug injectors with detention experience vs those without. HCV status could be independently predicted by both length and number of detentions. The increased risk of HCV could only be somewhat explained by injecting drugs while in detention.
