The Public Health Department gives the following advice on the most effective measures to control the further spread of this potentially serious illness:

Vaccination with measles containing vaccine (MMR):

• All children should get the MMR vaccine when they are aged 12 months. If any child aged over 12 months has missed this vaccine they should get it now from their GP.
• All children should get a second dose of MMR vaccine when they are 4-5 years old or in Junior Infants at school. If any child in Senior Infants or older has missed this vaccine they should get it now from their GP.
• Adults under 40 years who have not had measles or have not received 2 doses of MMR vaccine should contact their GP to get the MMR vaccine.
• Adults over 40 years of age may sometimes be at risk and if such adults never had measles nor a measles containing vaccine they should consider getting the MMR vaccine from their GP.

Measles symptoms include:

• High fever
• Cough
• Runny nose
• Red eyes
• Red rash that starts on head and spread down the body - this normally starts a few days after onset of illness. The rash consists of flat red or brown blotches, which can flow into each other. It lasts about 4-7 days
• Vomiting, diarrhoea and tummy pain may also happen.

Measures to prevent the spread of measles if you think you may have measles:

• Do not go to work, school or crèche.
• Stay at home and phone your GP. Tell the doctor or nurse that you think you might have measles.
• Stop visitors coming to the house to prevent the spread of measles.
• Pregnant women who have been exposed to measles should seek medical advice as soon as possible.
