The tests are being done at a facility called the Fever Clinic, which also cares for and isolates infected people within the so-called "Olympic bubble.” Once a COVID-19 infection is identified or suspected, “close contacts” also are tested to identify others who may be ill — a whack-a-mole process done under controlled conditions. Organizers wouldn't comment on the number of people working at the clinic or the specific arrangements. These tests don’t require sticking a swab up one’s nose, another widespread method of testing for the coronavirus. The tests for athletes, team officials, media and others affiliated with the Games are free to those submitting them, although they are estimated to cost about 10,000 yen ($100) each, medical say experts. Tests for members of the Japanese public generally cost about that much, sometimes more.
