China's financial hub Shanghai said on Sunday it will reopen all primary, middle and high schools, kindergartens and nurseries on September 1 after months of COVID-19 closures.
"The cluster has a wide distribution of infected people, who had many social activities, and there are hidden transmission risks in the community," the city government said in a statement.
China's two largest cities have contained COVID-19 following a bruising four-month fight that saw millions of residents locked in their homes, exhaustive testing and restrictions on daily life that impacted every facet of society and the economy.
Shanghai eased a range of Covid-19 restrictions on Wednesday in a step towards returning to normal after a two-month lockdown that confined residents of the megacity to their homes and battered China's economy.
