Britain's health ministry said there were no plans to halt rapid coronavirus testing, after the Guardian newspaper reported the programme may be scaled back in England because of concerns about false positives.

"With around one in three people not showing symptoms of Covid-19, regular, rapid testing is an essential tool to control the spread of the virus as restrictions ease by picking up cases that would not otherwise have been detected," a ministry spokeswoman said in an emailed statement, according to Reuters.

"Rapid testing detects cases quickly, meaning positive cases can isolate immediately, and figures show that for every 1,000 lateral flow tests carried out, there is fewer than one false positive result."
