The world hit a record number of Covid-19 infections in a seven-day period, with more than 935,000 cases detected on average each day between December 22-28, according to an AFP tally.

The figures, the highest since the virus first emerged at the end of 2019, are based on tolls given daily by health authorities in each country.

With 6,550,000 cases recorded between December 22 and December 28 — or an average of 935,863 a day — the virus is spreading at unprecedented speed.

The figures are sharply higher than the previous record between April 23-29 when 817,000 cases were recorded on average each day.
