There is likely to be considerable pushback from Government to recommendations that the country move to level 5 Covid restrictions.
An unscheduled meeting of the National Public Health Emergency Team (NPHET) on Sunday which lasted for several hours concluded with it recommending the country moves to the highest level of restrictions, or a full lockdown.
Government sources, speaking to the Irish Examiner, expressed their considerable surprise and concern at such a recommendation citing the potential economic and social impact on the country.
The Government will consider the recommendation from NPHET on the deteriorating national picture which sources described as “very worrying”.
The meeting was chaired by the Chief Medical Officer, Dr Tony Holohan who has returned to his post following an extended absence for personal reasons.
A decision to tighten restrictions will be considered by Government on Monday but more likely at its weekly Cabinet meeting on Tuesday.
Northern Ireland has recorded 462 new cases of Covid-19 in a 24-hour period.
There has been one further death reported by the Department of Health.
The death toll recorded by the department now stands at 584.
Meanwhile, in the US, Donald Trump went through a “very concerning” period on Friday and faces a “critical” next two days in his fight against Covid-19 at a military hospital, his chief of staff said.
Mark Meadows’ comments contrasted with a rosier assessment moments earlier by doctors treating the US president, who were at pains not to reveal that Mr Trump had received supplemental oxygen at the White House before being admitted to hospital.
Mr Trump offered his own assessment in a video from the Walter Reed National Military Medical Centre on Saturday evening, saying he was beginning to feel better and hoped to “be back soon”.
