Parents of young children are being urged to get their child vaccinated with the MMR jab, with the HSE on high alert for an outbreak here.
A man in his 40s, who'd contracted the virus, has passed away in hospital in the first case of the year reported here.
He died in a hospital in the Dublin and Midlands health region, and was reported to have recently travelled to England.
Member of the Irish Medical Organisation's GP committee, Dr Denis McCauley, explains what symptoms people should look out for
"It presents initially like quite a lot of normal viral illnesses, if you're exposed to somebody with measles approximately about a week later you will feel high temperature aches and pains you'll have quite a lot of watering of your eyes, what differs then is that sort of temperature tends to last for a week, you become quite immunosuppressed and you can develop spots on your tongue or you can develop a fine rash"
