Simplified HCV screening model schematic illustrating the key aspects of the screening and treatment intervention pathway. Broadly, the population is split into three categories: (i) those who have never been screened (and eligible for primary Ab screening), (ii) those who have been previously screened Ab- (and eligible for Ab re-screening), and (iii) those who have been previously screened Ab+ (i.e. known Ab+ status). The lattermost category of individuals with known Ab+ status is divided into two sub-categories to indicate whether they have ever been diagnosed or not. The full HCV screening model schematic, including demographic and behavioural compartments, disease progression stages, HCV transmission dynamics, and the screening and treatment intervention cascade of care can be found in Supplementary Figure S1.
