Britain reported 1,062 new positive tests for coronavirus on Sunday, the highest daily rise in new Covid-19 infections since late June, at a time of new local lockdowns in some areas and worries over a second wave of infections.
Official data showed 1,062 people tested positive for Covid-19 on Sunday, going over the 1,000 new daily cases mark for the first time since June, and 304 higher than the 758 new cases reported on Saturday.
In other news, Boris Johnson said reopening schools in September was a social, economic and moral imperative and insisted they would be able to operate safely despite the ongoing threat from the pandemic.
His comments follow a study earlier this month which warned that Britain risks a second wave of Covid-19 this winter twice as large as the initial outbreak if schools open without an improved test-and-trace system.
Writing in the Mail on Sunday, Johnson said restarting schools was a national priority. Schools would be the last places to close in future local lockdowns, he was quoted by another newspaper as telling a meeting on Thursday.
Schools in England closed in March during a national lockdown, except for the children of key workers, and reopened in June for a small number of pupils.
The government wants all pupils to return to school by early September in what Johnson has called a "national priority".
"Keeping our schools closed a moment longer than absolutely necessary is socially intolerable, economically unsustainable and morally indefensible," Johnson wrote.
The economic costs for parents who cannot work if schools are shut are spiralling, and the country faces big problems if children miss out on education, the prime minister warned.
"This pandemic isn't over, and the last thing any of us can afford to do is become complacent. But now that we know enough to reopen schools to all pupils safely, we have a moral duty to do so," he wrote.
The Sunday Times newspaper reported that he has ordered a public relations campaign to ensure schools open on time and told the meeting last week that they should be the last places to close behind restaurants, pubs and shops.
