There are no blood or tissue samples from ancient ages that can confirm the presence of this virus. Since this virus is an obligate virus (it cannot survive outside a living organisms – human or primates) there is no evidence of this virus from ancient ages.
How much did the hepatitis B virus decrease after a blood transfusion?
However, screening for the hepatitis B virus and exclusion of infectious donors resulted in a decrease of only 25 to 50 percent in post-transfusion hepatitis cases. It was assumed that the remaining cases were either caused by the hepatitis A virus, or by the hepatitis B virus that may have slipped through the screening process.
When did the era of direct-acting antivirals begin?
Zeroing in on the Hepatitis C Virus. The era of direct-acting antivirals (DAAs) that specifically target HCV began in 2011 with the U.S. Food and Drug Administration (FDA) approval of the first protease inhibitors.
What is non-A, non-B hepatitis?
The non-A, non-B hepatitis virus was identified in 1989 by scientists at a California biotechnology company called Chiron who were collaborating with investigators at the Centers for Disease Control and Prevention (CDC). The research confirmed that this was a new virus—now officially called the hepatitis C virus, or HCV. This was a landmark advance in medicine that allowed for development of tests to detect HCV, which were rapidly applied to screen blood donations. Over the next few years, as the testing improved, HCV was effectively eliminated from the blood transfusion supply. The identification of HCV also led to further studies, undertaken by NIAID- and NIDDK-funded researchers and others, to determine its molecular structure. This was crucial for the design of drugs that would specifically interact with components of the virus and inhibit its replication. The identification of the virus also allowed for a more accurate diagnosis and a better sense of its prevalence; in fact, it was eventually determined that HCV was the most common cause of chronic hepatitis, cirrhosis, and liver cancer in the Western world.

Why do tattoos cause hepatitis C?
This can be due to either improperly sterilized equipment or contamination of the dyes being used. Tattoos or piercings performed either before the mid-1980s, "underground", or nonprofessionally are of particular concern, since sterile techniques in such settings may be lacking. The risk also appears to be greater for larger tattoos. It is estimated that nearly half of prison inmates share unsterilized tattooing equipment. It is rare for tattoos in a licensed facility to be directly associated with HCV infection.
