Health officials are advising parents to look out for the signs of hepatitis after cases confirmed in Scotland rose to 13 - including cases in Lanarkshire.
All of the children affected were admitted to hospitals, where medics picked up on their illness - but the source of the outbreak has yet to be determined, despite ongoing investigations.
The UK Health Security Agency said it is examining 74 cases across the UK, with 49 in England and 12 each in both Wales and Northern Ireland.
