An outbreak of measles is affecting children in Powys, with cases concentrated in the north of the county.

Some 41 cases were notified during March, with almost 20 in the past week. Most of these have been in children of school age, where the disease can spread easily, but people of all ages can be affected.

Measles is a serious disease that can lead to long term health issues such as eye disorders, deafness , brain damage and even death. It is very important that everyone is vaccinated against this disease. One dose of the MMR (measles, mumps and rubella) jab will protect 90 per cent of children and the recommended two doses of MMR jab will provide 99% protection against measles. The MMR jab is safe and offers the only protection against measles.

In Powys 1 in 4 teenagers have not had two MMR jabs and are not fully protected against measles. The vaccine provides protection very quickly after being given and it is not too late to ensure that you and your family are protected.

If you or your family have not had the 'MMR' jab or you are unsure if they have had it, contact your GP to arrange to be vaccinated.

If you suspect that you or someone you know has measles, please telephone your GP to inform them prior to attending in order to reduce the risk of infecting others. Avoid going to A&E unless you are seriously ill and if you do attend, telephone ahead to let them know you or your child may have measles.
