All national dailies wrote that the Tokyo Metropolitan Government announced on Thursday that it has confirmed the first case of the Omicron variant of COVID-19 outside of airport screening. On Thursday a woman in her 20s living in Tokyo was confirmed to be infected with the variant. She returned from the United States on Dec. 8 and tested negative upon arrival at Narita Airport but developed a fever the next day while quarantining at home and was confirmed to be infected with the variant on Thursday. A man in his 20s, who also lives in Tokyo and is regarded as having been in close contact with the woman as they met on Dec. 8 and 9, also tested positive for COVID-19 on Wednesday. His sample is still being analyzed. The metropolitan government plans to ask about 80 people who sat near him at a soccer game at a stadium in Kawasaki, Kanagawa Prefecture, on Sunday to undergo testing.
Meanwhile, the Health Ministry announced on Thursday that a female staff member at the quarantine station at Kansai International Airport in Osaka also tested positive for the Omicron variant of COVID-19. She had reportedly been working at a facility housing people who tested positive for the coronavirus after arriving at the airport. Since she has no recent history of travelling overseas, this represents the first domestically acquired Omicron infection in Japan.
