Sligo University Hospital is now battling six flu outbreaks in separate wards.
This is a further increase on the five outbreaks on site last week.
In a statement issued this afternoon, management at the hospital confirmed that impacted wards include, Medical South, Medical Offsite, Surgical Gynae, Temporary Medical, Oncology and Medical 5.
Staff are currently treating 23 patients with flu across SUH with a particularly high number of older people and children attending the ED with symptoms.
As a necessary infection control measure, visiting restrictions remain at the hospital.
Only one visitor per patient is permitted across the hospital and children should not be brought to visit on adult wards.
Where a ward is managing a flu outbreak, visiting will be limited to compassionate grounds only.
Visiting is only between 6-8pm each day and visiting outside these hours can only be facilitated in exceptional circumstances and should be prearranged with the Clinical Nurse Manager 2 on the ward.
In order to control the risk of infection, everyone coming to the hospital must wash their hands and use hand gel regularly. If you are asked by staff to wear a face mask, please do so to help prevent the spread of serious respiratory illness to our sick and vulnerable patients. Face masks are widely available across the hospital.
Symptoms of flu include a high temperature, aches and pains, headache, sore throat or cough. If you have any of these symptoms, please do not visit a loved one in the hospital. You must postpone your visit until at least 48 hours after your symptoms have cleared, this will reduce the risk of spreading infection to vulnerable patients and healthcare staff.
These restrictions are temporary and subject to change based on daily activity levels so please check HSE.ie for information about visiting in your local hospital.
