To ask the Scottish Executive which population groups are at greatest risk of acquiring hepatitis C infection and what plans it has to test or screen these groups. Health Protection Scotland estimates that approximately 90% of the estimated 50,000 persons in Scotland, who have been infected with hepatitis C virus (HCV), are either former or current injecting drug users, and this population group is thus at greatest risk.In consequence, since HCV testing became available in 1991, thousands of injecting drug users in Scotland have been tested for HCV in the context of guidelines, distributed by the Scottish Executive Health Department, which recommend that all injecting drug users should be offered an HCV test.
