The main purpose of the study is to compare the efficacy of two strategies aimed to rescue patients lost to follow-up with active infection or with positive HCV antibodies without RNA request to complete evaluation and prescription of treatment in cases of chronic infection. After patient identification from data files of laboratory and microbiology charts, patients will be randomized to: a) phone call, and b) invitation letter, both of two strategies including a scheduled appointment with the hepatologist.
