Health officials have urged people to be vigilant following a measles outbreak in Sheffield.
The warning comes after vaccine rates among young children in the UK dipped to a 10-year low.
Latest figures show only 84.5% had received a second shot of the protective measles, mumps and rubella (MMR) jab – the lowest since 2010-11.
Anyone who suspects their child has symptoms is advised to stay at home and call 111 or their GP for advice.
Measles can make children very sick. The main symptoms are a fever and a rash but it can cause serious complications, including meningitis. For some, it is fatal.
