The Olympics Village opened on Tuesday under a state of emergency just ahead of the start of the Olympics on July 23. Athletes will be tested daily in the village, after being tested at least twice before leaving home, and again upon arrival.
They will also be required to wear masks in the village - even if they are vaccinated - and be reminded constantly with signage about social distancing, washing hands and ventilating room areas.
About 11,000 athletes are expected for the Olympics and 4,400 for the Paralympics, which commences on August 24.
The International Olympic Committee has said more than 80% of the occupants of the village will be fully vaccinated.
