都内「Ｎ５０１Ｙ」主流に　強い感染力、連休の人出警戒―新型コロナ

　東京都は２８日、新型コロナウイルスの感染状況などを分析するモニタリング会議を開催した。専門家は、都内の新規感染のうち感染力の強い「Ｎ５０１Ｙ」変異ウイルスが約６割を占め、主流になったとの推計を報告。さらに拡大する可能性があるとして、大型連休中の人出抑制を徹底するよう求めた。

A highly contagious coronavirus variant with the N501Y mutation is estimated to be causing nearly 60 pct of the total cases in Tokyo, experts reported Wednesday.
   Citing the Tokyo Metropolitan Institute of Public Health's data, the experts said at a coronavirus monitoring meeting held by the metropolitan government that the N501Y cases accounted for 59.6 pct in the week through Sunday, up sharply from the preceding week's 32.8 pct.
   Meanwhile, the seven-day average of new cases in the capital as of Tuesday climbed 18 pct from a week earlier to 716.4.
   Nighttime flows of people in downtown areas between April 18 and Sunday grew some three-fold from the levels during the first coronavirus state of emergency, declared in April last year.
   "If people have more opportunities to have contact with others during the Golden Week holiday period (starting Thursday), Tokyo may see cases increase faster than the spread seen in the third wave of pandemic," Norio Omagari, a doctor at the National Center for Global Health and Medicine, said at the meeting.
