This report provides an overview of norovirus and rotavirus activity in England during the 2023 to 2024 season. It is published weekly during the winter period and monthly during the summer period.
The data presented is derived from 4 national UK Health Security Agency (UKHSA) systems, including laboratory reporting of norovirus and rotavirus, enteric virus (norovirus, rotavirus, sapovirus and astrovirus) outbreaks in hospital and community settings, and molecular surveillance data on circulating strains of norovirus.
All surveillance data included in this report is 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 is not included.
Previous reports on norovirus and rotavirus activity are also available for:

This report provides an overview of norovirus and rotavirus activity in England during the 2022 to 2023 season. It is published weekly during the winter and monthly during the summer.
The data presented is derived from 4 national UK Health Security Agency (UKHSA) systems, including laboratory reporting of norovirus and rotavirus, enteric virus (norovirus, rotavirus, sapovirus and astrovirus) outbreaks in hospital and community settings, and molecular surveillance data on circulating strains of norovirus.
Many of the interventions implemented to minimise COVID-19 transmission, reduced social contact, increased hand washing and enhanced environmental cleaning, are also effective against norovirus and rotavirus. Therefore, it is likely that these interventions contributed to a reduction in norovirus and rotavirus transmission throughout 2020, 2021 and into the first half of 2022. However, there are other contributory factors such as (but not limited to) changes in ascertainment, access to health care services and capacity for testing.
This official statistics report was relaunched after it was temporarily suspended during the COVID-19 pandemic period due to data quality issues. Between December 2020 and October 2022, the report was replaced by the national norovirus and rotavirus bulletin to ensure an overview of norovirus and rotavirus activity in England continued to be available to the public.
Data covering the periods 2020 to 2021 and 2021 to 2022 is available:
Additional analyses in September 2022 demonstrated the data quality was again comparable with the data collected before the pandemic and therefore reporting resumed as an official statistic. Due to these changes, apparent trends should be interpreted with caution over the pandemic period.
All surveillance data included in this report is 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 is not included.
Note: from 20 October 2022, this report is published as official statistics. The week 32, week 36 and week 40 reports were not published as official statistics.

The sewage treatment worksdataset includes norovirus levels, ammonia concentrations and orthophosphate concentrations in wastewater from 3,232 samples and their associated metadata collected for the Environmental Monitoring for Health Protection (EMHP) programme between May 2021 and March 2022 from the untreated influent of 152 sewage treatment works across England. The samples are a subset of samples that were originally collected and analysed for SARS-CoV-2.
The **network dataset **includes all of the norovirus levels, ammonia concentrations and orthophosphate concentrations in wastewater from 220 samples and their associated metadata collected for the Environmental Monitoring for Health Protection (EMHP) programme between May 2021 and March 2022 from 11 sewerage network sites across England. "NETWORK" sites were located further upstream of the sewershed than the sewage treatment works (STWs). Network sites were typically used during the COVID-19 pandemic to get better spatially resolved data than was possible using sewage works alone.
