UKHSA Releases Week 31 Norovirus and Rotavirus Report

The UK Health Security Agency (UKHSA) has published its week 31 national norovirus and rotavirus surveillance report, incorporating data up to week 30, which ended on 26 July 2026. The release forms part of the agency's ongoing monitoring programme for the 2026 to 2027 enteric virus surveillance season.

Scope of the Report

The report is one in a series of periodic official statistics publications through which the UKHSA tracks norovirus and rotavirus in England. Each release in the series corresponds to a numbered surveillance week, with the underlying data running one week behind — in this case, week 30 data published under the week 31 designation.

The 2026 to 2027 season represents the current active surveillance period for enteric viruses, according to the UKHSA. The agency publishes these reports as official statistics, reflecting the structured, scheduled nature of the data releases.

Surveillance Context

Norovirus and rotavirus are both enteric viruses subject to routine surveillance in England. The UKHSA's reporting framework monitors their activity across the country on a rolling basis throughout each surveillance season, with reports released regularly to reflect the most recent available laboratory and outbreak data.
