Entry title:

Respiratory syncytial virus (RSV)

Last updated on Thursday, 8 January 2026 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.

Testing
