An Olympic coach from Uganda tested positive for COVID-19 upon arriving in Japan, where less than 7 percent of the populace has been fully vaccinated against the coronavirus. The announcement comes as many citizens of Japan are set against holding the games as scheduled, arguing it could fuel a new wave of infections. Ugandan officials said the coach, like the entire delegation, had been fully vaccinated before traveling. Eight who arrived with the unidentified coach are being quarantined—and the coach could be sent home.
