Three scientists who discovered the virus Hepatitis C have won the 2020 Nobel Prize in Medicine or Physiology. The BBC reports that the winners are British scientist Michael Houghton and US researchers Harvey Alter and Charles Rice. The Nobel Prize committee said their discoveries ultimately “saved millions of lives”. The virus is a common cause of liver cancer and a major reason why people need a liver transplant. “For the first time in history, the disease can now be cured, raising hopes of eradicating Hepatitis C virus from the world,” the prize committee said.
