On Monday, First Minister Arlene Foster said there were few options left to curb the current crisis, apart from a possible new curfew.
Mrs Foster and Deputy First Minister Michelle O'Neill said while Northern Ireland was past the peak of new cases, the lag between people becoming infected and needing hospital treatment meant inpatient numbers were yet to hit their peak.
Pat Cullen, the director of the Royal College of Nursing in Northern Ireland, says healthcare workers in the North are frightened about what will come in the next few weeks.
Hospitals there are preparing for a third surge in facilities of the Covid-19 pandemic.
On Monday, a further 16 Covid-related deaths were announced by the Department of Health in Northern Ireland. A total of 759 new cases of the virus were also reported.
