The medal presenters, typically members of the IOC or other guests, will be required to wear disinfected gloves, Bach said.
Athletes who finish on the podium at the delayed Olympic Games in Tokyo will put on their own medals, rather than having them draped round their neck, due to COVID-19 measures set to be in place at Tokyo 2020.
International Olympic Committee (IOC) President Thomas Bach announced a series of steps that will be taken during the medal ceremonies to limit the risk posed by the COVID-19 virus and described the change as "very significant."
The medal presenters, typically members of the IOC or other guests, will be required to wear disinfected gloves, Bach said.
They will place the gold, silver or bronze medal - made of entirely recycled consumer electronics - on a tray and the recipient will pick them up and place it around their own necks, in a break from a tradition that has been part of the Olympics for decades.
The move contrasts with UEFA's method at major tournaments held during the pandemic.
UEFA President Aleksander Čeferin presented the medals to winners Italy and runners-up England in the normal way after the final of the European Championship on Sunday (July 11), as well as the Champions League and Europa League in May.
