Hepatitis C Treatment Uptake among People Who Inject Drugs in Oslo, Norway: A Registry-Based Study.

•Among 2436 participants with chronic HCV 1118 (45.9%) had received HCV treatment during the study period.•Treatment rates increased significantly during the study period (2010–2019), and exceeded a previously modelled elimination threshold of 50/1000 PWID after DAA access became unrestricted.•Treatment uptake was less likely among women and those aged 40–49 years, and more likely among participants on OAT.•Although HCV treatment uptake among PWID increased, strategies to improve treatment among women and individuals not engaged in OAT should be addressed.
