Hepatitis C is a viral disease that leads to inflammation of the liver, and is part of the Hepatitis virus family, Flaviviridae, of which A and B are the most well known. Chronic hepatitis C virus (HCV) infection leads to scarring of the liver and cirrhosis, which a significantly heightened chance of liver failure and/or liver cancer. While HCV occurs only in human and chimpanzees, it is a highly transmissible virus that occurs through blood contact often in medical, hard labor intensive, sexual intercourse and intravenous drug use settings. Hepatitis C infections are predominantly treated with a medication cocktail consisting of peginterferon and ribavirin, which had a 50% success rate, and would commonly induce multiple side effects such as flu-like symptoms, anemia and depression (Terhune and Brown, 2014). In late 2013, the Federal Drug Administration approved two new non-interferon antiviral drugs to treat Hepatitis C, Gilead's Sovaldi (sofosbuvir) and Johnson and Johnson's Olysio (simeprevir). In test trials involving 197 patients who were not responsive to interferon, the paired administration of Sovaldi and Olysio was shown to clear 90 percent of the Hepatitis C virus (Sheridan, 2014). These two novel drugs will be important in the next few years for curing patients with Hepatitis C, especially if costs can be brought down.
