All children who have not been fully immunised face a life-long risk of catching measles.
Most people make a full recovery but there is a rare possibility of severe complications including serious eye disorders, deafness, brain damage and even death.
Measles can be prevented by use of the safe and highly effective measles, mumps and rubella (MMR) vaccine.
Parents can easily protect their children by having them immunised with the MMR vaccine. After completing a two-dose course of MMR, 99 per cent of children will be protected against measles.
Parents of all children aged between one and 18 who have not been fully vaccinated are being advised to contact their GP for advice and to get their child vaccinated as soon as possible.
