Visiting restrictions are in place at Letterkenny University Hospital today.

An outbreak of a vomiting and diarrhea bug in three wards has forced the hospital to cancel all visitation.

Medical Wards 5 and 3 and Surgical Ward 2 are the areas effected.

In a statement the hospital confirmed that in exceptional circumstances next of kin should ring the ward directly to make arrangements for visitation.

They are also urging anyone who is experiencing symptoms at home to not visit the hospital under any circumstances.

17 people are on trolleys in the hospital today with 8 waiting for admission from the emergency department of Sligo University Hospital.
