Changes to when we publish influenza and RSV data
We are changing how often we publish our influenza and RSV data. From 29 May, we will update metrics for both influenza and RSV every 2 weeks instead of weekly. We will resume weekly updates in October this year.
Entry title:
Respiratory syncytial virus (RSV)
Last updated on Thursday, 22 May 2025 at 04:00pm
Respiratory syncytial virus (RSV) is one of the common viruses that cause coughs and colds in winter. RSV causes mild symptoms in most people, but can be serious for some infants, older adults and people with chronic medical conditions.
The testing data we have for RSV comes from a sentinel surveillance system (a data collection method used to monitor trends). This means there are limitations to these data. Find out more about data collection for RSV.
During the autumn and the winter we update RSV testing metrics every Thursday at 4pm.
