Hepatitis C: Data

Hepatitis C virus infection is the most common bloodborne infection in the United States, impacting an estimated 1% of the population or 2.4 million people. In the U.S. and Wisconsin, there are two populations most commonly affected by hepatitis C:

• Younger adults who were most likely recently infected through injection drug use.
• Older adults, including baby boomers born during 1945-1965, who were most likely infected many years ago but are only now being diagnosed with hepatitis C.
