An outbreak of mumps has hit the counties of Sligo, Leitrim and Donegal.
So far locally there have been over twenty reported cases this year with four of those cases having been confirmed in the last week.
45 people alone have been affected with the condition recently in West of Ireland alone.
There were 319 cases across the country recorded in the whole of last year.
