Dataset:Coronavirus (COVID-19) infections in the community in the UK
Corrections and notices
19 April 2021
Following this release, we identified a number of quality issues:
our grouping of 'classic' symptoms had excluded fever when it should have been included in that category
results from a small number of participants who had experienced a positive test followed by a negative test within the 35 day period of the analysis had been previously excluded from the analysis due to a coding error
estimates for March were based on data from 1 March to 20 March 2021 and should have used available data up to and including 22 March 2021
These corrections have resulted in a change to the estimated percentage of people reporting any symptoms from 47% to 49% and the estimated percentage of people reporting no symptoms has changed from 53% to 51%. The estimated percentage of people reporting 'classic' symptoms has also changed from 36% to 43% and there are additional changes to data for past time periods.
These changes have not affected the main trends presented in this release. We are reviewing our quality assurance procedures and apologise for any inconvenience caused.

We have updated the labelling for tabs 2a and 2b in the reference tables, to accurately reflect the groups included in the analysis.
We apologise for any inconvenience.
