Belfast's Mater Hospital is set to be the main treatment centre for patients affected by the coronavirus in the city.
The BBC reported that wards at the Crumlin Road hospital have been identified and preparations are ongoing for the treatment of seriously ill patients.
After five new cases were detected on Sunday there are 12 confirmed cases in Northern Ireland with 21 in the Republic of Ireland.
A spokesperson for the Belfast Trust said: "Belfast Trust like all trusts is planning to provide care for the number of positive Covid-19 patients who may need hospital care in the coming weeks.
"These arrangements will involve identifying wards and units and prioritising care for the sickest patients. The Trust is looking how best to do this across all acute sites including the Mater Hospital."
