Shanghai's education bureau has asked most grades in primary, middle and high school to hold classes online from Monday as worsening COVID-19 infections hit major cities across China.
The bureau on Saturday also asked kindergartens and childcare centres in the financial hub to shut all in-person classes from Monday, according to an online statement.
China last week jettisoned some of the world's toughest anti-COVID curbs and is now experiencing a spike in infections, with fears COVID could sweep across its 1.4 billion population during next month's Lunar New Year holiday.
