About Hepatitis C Hepatitis C is a serious liver disease caused by the hepatitis C virus, which is spread through direct contact with the blood of infected people and ultimately affects the liver. 1 Chronic hepatitis C can lead to serious and life-threatening liver problems, including liver damage, cirrhosis, liver failure or liver cancer. 1 Though many people with hepatitis C may not experience symptoms, others may have symptoms such as fatigue, fever, jaundice and abdominal pain. 1 Unlike HIV and hepatitis B virus, chronic hepatitis C can be cured. 2 If treatment is not successful and a person does not achieve a viral cure, they remain at an increased risk for progressive liver disease. 3,4 More than 170 million people worldwide are chronically infected with hepatitis C. 5 In the United States, up to 5 million people have chronic hepatitis C and 75 percent of them are unaware of their infection. 6,7 Hepatitis C is four times more prevalent in the United States compared to HIV. 7 The majority of people with hepatitis C in the United States were born between 1945 and 1965, accounting for 82 percent of people with the disease. 8 Hepatitis C is the leading cause of liver transplantations in the United States and is reported to contribute to 15,000 deaths annually. 9,10 By 2029, total annual medical costs in the United States for people with hepatitis C are expected to more than double, from $30 billion in 2009 to approximately $85 billion. 11 About Vertex Vertex creates new possibilities in medicine.
