This bulletin provides an overview of norovirus and rotavirus activity in England during the winter of the 2020 to 2021 season. The data presented are derived from 4 national Public Health England (PHE) surveillance systems, including laboratory surveillance of norovirus and rotavirus, enteric virus (norovirus, rotavirus, sapovirus and astrovirus) outbreaks in hospital and community settings, as well as molecular surveillance data on circulating strains of norovirus.

This fortnightly bulletin temporarily replaces the Official Statistics national norovirus and rotavirus report. The report is currently suspended due to the adverse impact of the coronavirus (COVID-19) pandemic on the sampling and testing for enteric viruses and the reporting of these results to PHE, which mean it is not possible to ensure the accuracy and consistency of these data with previous seasons.

It is likely that the interventions implemented to control COVID-19 have contributed to a reduction in norovirus and rotavirus transmission. However, there are other contributory factors such as but not limited to changes in ascertainment, access to health care services and capacity for testing. Therefore, this bulletin summarises the surveillance data held by PHE and does not provide an in-depth interpretation relative to previous seasons as the Official Statistics national norovirus and rotavirus report has done in the preceding seasons.

All surveillance data included in this report are extracted from live reporting systems, are subject to a reporting delay and the number reported in the most recent weeks may rise further as more reports are received. Therefore, data pertaining to the most recent 2 weeks are not included.

Trends should be interpreted with caution due to current national advice and guidance regarding access to health care services during the COVID-19 pandemic.
