The HSE says this morning's cyber attack on its IT system has resulted in considerable delays at University Hospital Kerry's Emergency Department.
It also impacted on the hospital's ability to deliver normal outpatient services.
The HSE says this challenging situation is ongoing.
As a result management at UHK wish to advise the public that all routine outpatient appointments, including radiology and cardiology, have been cancelled other than for patients who have received direct contact from the hospital.
Management at UHK is reminding the public that the Emergency Department is for emergency services only.
Meanwhile, anyone who has symptoms of Covid-19 or who has been identified by Public Health as a close contact can attend walk-in testing at the existing HSE test centres this weekend without an appointment.
As it is not possible to issue appointments, the HSE cannot predict the demand at any given time and apologises in advance for any wait times.
The HSE says it is of critical importance that anyone who is a close contact or with symptoms continue to self-isolate while awaiting test results.
The Tralee centre is open 9.30am to midday and 2pm to 5pm on Saturday; 2pm to 5pm on Sunday.
The HSE says it will continue to post udpates on its website and Twitter.
