児童生徒、１月に９．８万人感染　「第５波」大幅超―文科省

　文部科学省は１５日、新型コロナウイルスの感染が確認された幼稚園児と小中高などの児童生徒は１月だけで約９万８０００人に上ったと発表した。これまで月別の感染者数が最も多かったのは、「第５波」だった昨年８月の約３万７０００人で、２倍以上に増えた。
　感染経路別では、「不明」の割合がすべての学校種で最多となり、幼稚園と小中学校ではこれまで最多だった「家庭内」を上回った。変異株「オミクロン株」の感染急拡大で、感染経路を追い切れなくなった影響とみられる。高校は「学校内」が不明に続いて多く、部活動を通じた感染が目立った。（2022/02/15-18:25）

A total of about 98,000 kindergartners, and students at elementary, junior and senior high, and special-needs schools in Japan were infected with the novel coronavirus in January, the education ministry has said.
   The figure represented the highest monthly total on record, far outpacing the previous high of around 37,000 marked in August last year, when the country was in the fifth wave of COVID-19 infections.
   Of the total, 51,535 were elementary school children, 24,091 senior high school students, 18,225 junior high school students, 3,576 children attending kindergartens and 998 students at special-needs schools.
   The proportion of children who did not know how they caught the virus was highest for all school types in January, according to the ministry.
   The share of children with unknown infection routes exceeded that of those getting the virus from infected family members for the first time for kindergartners, and elementary and junior high school students. Infection through family members had been the most common route for contracting the virus for these groups.
