British tourists are being urged to do one thing in order to avoid "ruining" their holiday this autumn. The UK Health Security Agency (UKHSA) has issued the guidance to travellers on social media.

The agency is urging people to make sure they're protected against measles before jetting off abroad. It comes amid a potential rise in infections this year. The highly-contagious illness causes fever, cough, red eyes and a rash, but can be prevented effectively by the MMR vaccine.
