The 2020 Nobel Prize in medicine for the discovery of hepatitis C virus: An epic saga of the fight against a troublesome virus

Abstract

Chronic hepatitis C, which is caused by the hepatitis C virus, represents a substantial health threat to humans and causes approximately 700,000 deaths each year worldwide. However, 30 years after the discovery of this virus in 1989, nearly perfect antiviral drugs that can clear up to 95% of this virus have been developed due to numerous biomedical research studies and cooperation among members of the hepatitis C community. Because of these advances, the WHO announced a goal to eliminate the hepatitis C virus globally by 2030. Reviewing prior advances in detail, it is clear that all these achievements are based on initial seminal research conducted by the three 2020 Nobel laureates in medicine, namely, Harvey J. Alter, Michael Houghton and Charles M. Rice. In this short essay, we describe the seminal studies conducted by these authors. At the same time, the impacts of the contributions of these researchers on subsequent developments in research and in the treatment of chronic hepatitis C are honored.
