North Dakota Department of Corrections and Rehabilitation (NDDOCR) data from 2009 to 2018 was used and period prevalence was calculated for this 10-year time period. The period prevalence of HCV infection was (15.13% (95% CI 14.39-15.90) with a marginally significant (p-value: 0.0542) increasing linear trend in annual prevalence over this period. Multivariate logistic regression analysis was used to identify risk factors associated with HCV infection. The main significant independent risk factors for HCV infection in this incarcerated population were age >40 years [OR: 1.78 (1.37-2.3PloS oneEpidemiology of Hepatitis C virus infection among incarcerated populations in North Dakota.PMC8963564G17.1102Jansen RJPinks KHagan JJNjau GChandra Deb LHove HMiller TKfalseEpidemiology of Hepatitis C virus infection among incarcerated populations in North Dakota.This retrospective cohort study was conducted to determine the prevalence of HCV infections among individuals incarcerated in a state prison system and identify potential contributing factors to HCV infection.
