Twenty new cases of measles have been reported as the outbreak in the Swansea area continues.
Public Health Wales is continuing to urge parents to ensure their children receive the MMR vaccination as it investigates the new cases in the Swansea and Neath Port Talbot area.
The new cases bring the total number of cases to 209. The majority of the latest infections are in the Swansea area.
Dr Marion Lyons, Director of Health Protection for Public Health Wales, said that "measles is a very contagious disease."
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.
