Mumps notifications and confirmed cases by oral fluid testing: 2013 to 2025 by quarter
Following the Measles-Rubella (MR) school campaign in November 1994, the Public Health England, now UK Health Security Agency (UKHSA), predecessor (Public Health Laboratory Service) has offered oral fluid testing to confirm the diagnosis on all notified cases of measles, mumps and rubella. This is part of the enhanced surveillance programme for these vaccine preventable diseases.
The table below shows only the cases confirmed through IgM antibody testing of an oral fluid or serum sample, or through a PCR test.
