The Belfast Health Trust is scaling back on some planned operations as preparations step up to deal with an increase in the number of people with coronavirus in Northern Ireland.
A Trust spokesperson said elective surgery has not been cancelled but a very small number of produces, less than five, are not going ahead but the vast majority are continuing.
"Like all Trusts, we are planning to provide care for patients who are positive with Covid-19 and who will need hospital care in the coming weeks," the spokesperson added.
"These arrangements will involve identifying wards and prioritising care for the sickest patients. We are looking at how best to do this across all our sites."
The Mater Hospital will be the main site that will deal with the majority of cases.
Similar measures are being introduced in the Western Trust.
