33 cases of measles have been confirmed here since May.

The HSE says it's continuing to implement control measures to limit the outbreak.

Most of the cases were in children under the age of 10.

People who are vaccinated with two doses of the MMR vaccine are normally protected but the HSE is advising people to be extra vigilant.

Babies younger than 12 months old, non immune pregnant women and those with a weakened immune system are most at risk.
