Measles cases have seen a spike amid fears of a summer surge in outbreaks driven by mixing on holidays and at music festivals.
The UK Health Security Agency is calling on parents to check their children are up to date with their MMR vaccinations after detecting 49 cases between January and April. This compares to 54 cases in the whole of 2022.
Measles is a highly infectious disease that can lead to serious problems such as pneumonia, meningitis, and on rare occasions, long-term disability or death. Symptoms include a high fever, sore red watery eyes and a blotchy red brown rash.
