The death rate for coronavirus patients in English hospitals has fallen to a quarter of the level at the peak of the outbreak, which may mean that doctors are getting better at treating it.
Researchers said it was also possible that the data had a less optimistic explanation, possibly reflecting changes in those being admitted to hospital.
At the beginning of April, when there were 15,000 people in hospital with Covid-19, about 6 per cent died. Since then, the number in hospital has fallen by 2.4 per cent a day, meaning numbers have halved every 29 days.
At the same time the number of deaths has reduced by 4.3 per cent a day, meaning that it has halved every 16 days. As a consequence, in the latest figures the hospital death rate has fallen to 1.5 per cent.
Statisticians are struggling to explain the findings, which imply that patients are more likely to survive today than they were three months ago.
(goes on to mention possibly earlier admission to hospital, only taking very severe cases at the start due to being overwhelmed)
