「ＢＡ．２」７割に上昇　第７波阻止へ「重要局面」―東京都会議

　東京都は７日、新型コロナウイルスのモニタリング会議を開いた。専門家は、都内の陽性者のうち、オミクロン株の別系統で感染力がより強いとされる「ＢＡ．２」疑い例の割合が７割近くに達したとする検査結果を報告。「今後感染が急拡大するかどうか重要な局面を迎えている」との認識を示し、感染の「第７波」到来を防ぐため、対策の徹底を訴えた。
　都によると、３月２２～２８日の１週間のＢＡ．２疑いの割合は６７．８％で、前週（同１５～２１日）の５２．３％から増加。新年度に入って人の動きが活発化し、４月２日時点の夜間繁華街の滞留人口も、コロナ対策の「まん延防止等重点措置」期間中に比べ３７．６％増えた。（2022/04/07-16:36）

The BA.2 subvariant of the omicron variant of the novel coronavirus, which is believed to be more infectious than the original variant, is now suspected to be accounting for nearly 70 pct of COVID-19 cases in Tokyo, experts reported at a metropolitan government meeting on Thursday.
   The experts warned that Tokyo is facing a critical moment that will determine whether infections will rapidly spread again, calling for taking thorough measures to prevent a seventh COVID-19 infection wave in Japan.
   According to the Tokyo metropolitan government, the proportion of coronavirus patients suspected of being infected with the subvariant rose to 67.8 pct in the Japanese capital in the week through March 28 from 52.3 pct in the preceding week.
   The number of people out and about at night at entertainment districts in Tokyo on Saturday was 37.6 pct higher than when the Japanese capital was in the COVID-19 pre-emergency stage.
   In a bid to prevent a further spread of the coronavirus, the Tokyo government is stepping up efforts to encourage young people, whose COVID-19 vaccination rates are relatively low, to get vaccinated.
