Regardless of its etiology (chronic hepatitis B or C, alcohol consumption, metabolic steatohepatitis, hemochromatosis, autoimmune liver disease), cirrhosis is a real public health issue. Cirrhosis is a chronic disease and can get complicated by liver cancer, digestive hemorrhage, or liver failure, which are responsible for morbidity and mortality. In France, cirrhosis prevalence is estimated at 700,000 patients and induce 16,000 deaths per year (10,000 liver cancer and 6,000 liver decompensation). In Ile-de-France area, cirrhosis prevalence is estimated at 130,000 cases, a lot of them are in Seine Saint Denis department due to precariousness. Hepatitis C virus can now be cured and hepatitis B treatment can suspend hepatitis B replication. All these treatments reduce liver complications but even after virological cure, cirrhosis requires dedicated long term management as well as alcoholic liver disease and metabolic steatohepatitis at cirrhosis stage. Periodic screening for complications and specific measures were defined by french HAS in 2007 (medication intake, dietary management and specific vaccinations), especially the performance of a semi-annual liver ultrasound for hepatocellular carcinoma (HCC) screening. Then, it seems essential to screen for patients with viral hepatitis and extensive fibrosis or cirrhosis in our department to achieve active and individualized management of this chronic liver disease, to reduce long term morbidity and mortality. The main aim of the study is to evaluate the prevalence of advanced liver fibrosis and viral infections B and C in the general population of Seine Saint Denis, using a dual screening method of TROD (rapid diagnostic orientation test) and FibroScan®, combined with a care pathway
