Details
These reports summarise the surveillance of influenza, COVID-19 and other seasonal respiratory illnesses.
Weekly findings from community, primary care, secondary care and mortality surveillance systems are included in the reports.
Due to the COVID-19 pandemic, for the 2021 to 2022 season the weekly reports will be published all year round.
This page includes reports published from 15 July 2021 to the present.
Due to a misclassification of 2 subgroups within the Asian and Asian British and Black and Black British ethnic categories, the proportions of deaths for these ethnic categories in reports published between week 27 2021 and week 29 2021 were incorrect. These have been corrected from week 30 2021 report onwards. The impact of the correction specifically affects the proportion of deaths with an Asian and Asian British and/or Black and Black British ethnic categories. The total number of deaths reported was unaffected. Other ethnicity data included in the reports were not affected by this issue.
