An American Jewish scientist joined a countryman and a Briton on Monday in winning the 2020 Nobel Prize for Medicine for their work in identifying the Hepatitis C virus, which causes cirrhosis and liver cancer.
The discoveries - which were made by Americans Harvey Alter and Charles Rice and Briton Prof. Michael Houghton - meant there was now a chance of eradicating the Hepatitis C virus completely, the award-giving body said.
"Prior to their work, the discovery of the Hepatitis A and B viruses had been critical steps forward," the Nobel Assembly at Sweden's Karolinska Institute said in a statement on awarding the prize of 10 million Swedish crowns ($1.1 million).
"The discovery of Hepatitis C virus revealed the cause of the remaining cases of chronic hepatitis and made possible blood tests and new medicines that have saved millions of lives."
While the Nobel awards will go ahead as planned this year, they have been overshadowed by the coronavirus pandemic.
The Nobel Foundation has cancelled the traditional banquet, which forms the centerpiece of the celebrations in December, and will hand out the medals and diplomas in a televised event rather than live in Stockholm.
This year's winners will be invited to celebrate alongside the 2021 laureates, assuming the pandemic has eased by then.
Medicine is the first of the Nobel Prizes awarded each year.
The prizes for achievements in science, peace and literature have been awarded since 1901 and were created in the will of dynamite inventor and businessman Alfred Nobel.
