Symptom-tracking app records near-75% drop in UK's possible Covid-19 cases

The number of people recording symptoms of Covid-19 in the UK has fallen by almost 75% in just over two weeks, according to the latest data from a special symptom-tracking app.
Researchers from King’s College London, who helped design the app, said the figures have dropped from two million to 582,640 from the beginning of April, but warned that now was “definitely not the time for complacency”.
