Wales health officials have declared a measles outbreak as six confirmed cases have been reported in South East Wales.
Confirmed cases have been reported Cardiff, Newport and Blaenau Gwent with probable cases under investigation.
Public Health Wales said although cases are distributed across South East Wales, the first few cases are thought to have been exposed to an unknown highly infectious case in early February. This is because investigations have revealed that all were in the same location in Cardiff city centre on the same day.
The outbreak has prompted health officials to urge young adults and teenagers to make sure they are protected against measles with two doses of the MMR vaccine. In addition, parents are also urged to make sure their children are fully protected.
