Hepatitis C Infection Is the Most Common
Chronic Blood-Borne Infection in the US
• Accounts for up to two-thirds of newly diagnosed chronic liver disease cases1,2
• Contributes to significant morbidity (cirrhosis, liver failure, liver cancer), extrahepatic complications, and mortality3-5
• Leading cause of liver transplantation1,3
– Responsible for 41% of transplants6

§CDC recommendations. USPSTF recommendations state “other percutaneous exposures (such as in health care workers or from having surgery before the implementation of universal precautions).”
ALT=alanine aminotransferase.
• However, many persons infected with HCV do not recall or report having any of the risk factors listed in the above table1

The Rate of Disease Progression Is Estimated to
Increase With Duration of Hepatitis C Infection
• After 30 years of HCV infection, ~40% of patients are estimated to progress to cirrhosis

The Majority of People With Hepatitis C
Infection Remain Undiagnosed and Untreated
• Approximately 50% of individuals with HCV infection are unaware they are infected1,2
Estimate of Chronic HCV Infection Prevalence Versus
Infections Diagnosed and Treated in the US*
• Majority of those diagnosed are not successfully treated2,3
*Prevalence estimate based on NHANES data from 1999 through 2002. 4,5 NHANES data likely underestimate the actual prevalence of HCV in the US by not accounting for incarcerated, homeless, hospitalized, nursing home and active military duty populations. 6,7
