A coronavirus cluster has been found at a Japanese hotel hosting a number of Brazilian Olympic athletes, just 10 days before the Summer Games are due to begin.
The cluster emerged in the coastal city of Hamamatsu, with seven staff members confirmed to have the virus.
Those infected are reported not to have had any contact with the Brazilian delegation, which includes judo athletes.
Members of South Africa’s Olympic rugby team are also isolating after a passenger on their plane to Japan tested positive for Covid.
But International Olympic Committee head Thomas Bach said that out of 8,000 tests carried out on those arriving for the Games, only three have been positive.
Japan is battling a resurgence of the virus, with a record daily high of 1,149 newly confirmed cases reported on Wednesday. That’s almost double the number of new daily cases recorded last week.
A state of emergency will run through the entire period of the Games.
