The American Association for the Study of Liver Diseases (AASLD)/Infectious Diseases Society of America (IDSA) have updated their hepatitis C guidelines to reflect several important developments, including the approval of glecaprevir/pibrentasvir and sofosbuvir/velpatasvir/voxilaprevir for the treatment of all genotypes of hepatitis C virus.See Management: approach
Transmission is through percutaneous exposure to infected blood, most commonly through injection of illicit drugs or transfusion of contaminated blood products in developed countries, or via contaminated medical or dental equipment in resource-poor countries.
Following acute exposure to hepatitis C virus, about 55% to 85% of patients develop chronic hepatitis C.
Most infections are asymptomatic; however, hepatic inflammation is often present and can lead to progressive hepatic fibrosis.
The goal of treatment is to eradicate the virus, achieve a sustained virological response, and prevent disease progression.
Oral direct-acting antiviral therapies are standard treatment; therapy is evolving at a rapid pace.
Long-term complications of chronic infection include cirrhosis or hepatocellular carcinoma.
Hepatitis C virus (HCV) is an infectious, hepatotropic virus belonging to the Flavivirus family.  Infection may present as an acute illness (e.g., fatigue, arthralgia, jaundice) in approximately one third of patients; however, the majority of patients are asymptomatic. Chronic infection causes liver inflammation and fibrosis, and a significant number of these patients will develop cirrhosis and liver failure or liver cancer over a period of approximately 20 to 50 years. The infection rarely resolves spontaneously in patients with chronic infection.
