There was an error in the previously published data for Quarter 3 (July to Sept) 2020 in which a small number of cases were excluded from the analysis.

This happened because of human error. We apologise for any inconvenience caused.

This error has been corrected in the October 2021 to March 2022 edition, in addition to methodological improvements including reweighting on the latest population estimates.
