More than 15,000 coronavirus cases have been missed off last week’s daily reports.
Yesterday, 12,872 positive tests were reported in the daily figures, which was more than double the previous 24 hours.
The government put this down to a technical issue, saying there has been a delay in publishing a number of cases.
They have now identified more than 15,000 cases which were not included in the daily reports between September 25 and October 2.
Today’s update brings the UK total to more than half a million cases.
For example, 4,786 cases which were due to be reported on October 2 were not included in the daily total on the dashboard that day, when the figure was given as 6,968.
Michael Brodie, the interim chief executive at Public Health England, said: “A technical issue was identified overnight on Friday 2 October in the data load process that transfers Covid-19 positive lab results into reporting dashboards.
“After rapid investigation, we have identified that 15,841 cases between 25 September and 2 October were not included in the reported daily Covid-19 cases. The majority of these cases occurred in most recent days.
“Every one of these cases received their Covid-19 test result as normal and all those who tested positive were advised to self-isolate.
“NHS Test and Trace and PHE have worked to quickly resolve the issue and transferred all outstanding cases immediately into the NHS Test and Trace contact tracing system and I would like to thank contact tracing and health protection colleagues for their additional efforts over the weekend.
“We fully understand the concern this may cause and further robust measures have been put in place as a result.”
