The World Health Organization (WHO) estimates that 185 million people globally are infected with Hepatitis C virus (HCV), with 3 to 4 million new infections each year.
Roughly 75% of these cases fail to resolve acutely and evolve into a chronic state. Some recent estimates suggest that there could be as many as 8 milllion people (2.5% of the population) in the U.S. A slightly greater number of cases exists in Europe (7-12 million), with a large infected population in Asia (70 million+).
