The pair tested positive last week and further investigations revealed they had been eating in a group with two other village workers - in violation of the organising committee's own Covid--19 countermeasures.
The other workers have tested negative for the virus.
So far, an athlete and a coach from the Ugandan team, as well as a Serbian athlete have tested positive.
All were picked up at the airport or in separate accommodation outside the village.
The Olympic village is not open to athletes yet and will not be for another week.
