The HSE said in a statement that management in Letterkenny wish to advise that visiting the Short Stay Ward in the hospital has been suspended for the time being due to cases of norovirus on the ward.
It came just hours after it emerged that ambulance-bound patients were sent to Sligo on Monday due to a shortage of junior doctors in the Emergency Department.
There is ongoing criticism of management – with staff said to be over-stretched due to shortages in several departments.
Following the flu outbreak, the HSE said: “If relatives are concerned about patients on this ward, a nominated person from each family can liaise with the Clinical Nurse Manager on the ward regarding planned visiting. The contact number is 074 912 5888, extension 4084.
“People who have vomiting and diarrhoea symptoms should not attend the hospital but should contact their GP in the first instance if they have serious concerns.”
The statement added: “We would like to thank patients and the public for their cooperation.”
