Hepatitis C is a major health problem that affects approximately 2 to 4 million people in the United States, 5 to 10 million people in Europe, and 12 million people in India. Approximately 150,000 new cases occur annually in the United States and in Western Europe, although accurate incidence rates are difficult to estimate given the asymptomatic nature of the early stages of the disease. While the prevalence of the disease appears to be declining, hepatitis C is still highly prevalent in certain areas of the world. Egypt is the country with the highest prevalence of HCV, HCV-associated cirrhosis, and hepatocellular carcinoma, and the prevalence tends to increase with age, suggesting ongoing development of new cases of HCV. Approximately one-fourth of all cases of cirrhosis and hepatocellular carcinoma are attributed to HCV worldwide. Hepatitis C affects males and females equally.
