Hepatitis C: 25 Years of Discovery

2014 marks the 25th anniversary of the discovery of the Hepatitis C virus. Since the virus was discovered in 1989, significant public health and research advances have led to great progress in curbing new infections and developing life-saving treatment options. Unfortunately, millions of Americans continue to live with this disease and most don’t know they are infected. Explore this timeline to learn more about the highlights and milestones from the past 25 years of Hepatitis C discovery.

CDC issues recommendations for one-time testing for Hepatitis C for everyone born 1945-1965. Data shows that those born from 1945 - 1965 account for 75 percent of all Hepatitis C infections in the United States and 73 percent of Hepatitis C-associated mortality. The inaugural National Hepatitis Testing Day was celebrated on May 19, 2012.
