Hepatitis C is an infection of the liver caused by the Hepatitis C virus (HVC). The infection can be initially asymptomatic, however, if left untreated for a prolonged period of time, can result in liver scarring and cirrhosis, liver cancer, and liver failure. Hepatitis C can be transmitted through blood-to-blood contact which usually occurs through the use of poorly sterilized medical equipment, intravenous drug use, and transfusions. About 15% of people infected develop acute infections. Early stage symptoms of infection include fatigue, fever, nausea, loss of appetite, muscle and joint pain, and yellowing of the skin and whites of the eyes. About 80% of those exposed to the virus develop chronic infections which are more serious and can require a liver transplant. There is no vaccine for Hepatitis C, however, it can be treated with medication.
