The Minister of Communities has confirmed that she will self-isolate for two weeks after a member of her close family has tested positive for Covid-19.
Carál Ní Chuilín said she had informed the President of the Executive of Northern Ireland that she would be working remotely.
Deputy Prime Minister Michelle O’Neill is also self-isolating after a parent tests positive for Covid-19.
This is because 1,066 new cases have been reported by the Ministry of Health, with one additional death.
This is the second daily number of cases reported in Northern Ireland, after 1,080 positive cases were recorded on Friday.
There are now 137 hospital patients with Covid-19 in hospitals across Northern Ireland, 19 of whom are in intensive care.
The latest figures show 5,909 people have tested positive in the past seven days.
Sinn Féin Vice President Ms O’Neill said she would “continue to self-isolate” after testing negative for Covid.
Meanwhile, in a tweet, Ms. Ní Chuilín said that she “will fulfill my responsibilities”.
- How would a circuit breaker work for NI?
Meanwhile, South Down MP Chris Hazzard said the “alarming rise in infections” “had the minds of ministers” centered around the executive table.
He said he believed the issue of lockdowns would be considered by the Northern Ireland executive on Monday and said collective action was needed this week.
“I think there was logic and meaning to local lockdowns both, but I think we are now heading into an area where we again need to consider a more general lockdown,” he said.
“More general rigorous and robust methods to be able to remove this virus. ”
Mr Hazzard told the BBC’s Sunday Politics program in Northern Ireland that health must come first.
“There is no strong economy without strong public health,” he said.
Republic Minister for European Affairs Thomas Byrne said a circuit breaker was “clearly being considered” by the Irish government.
Speaking on the same agenda, he said closer alignment was needed between Northern Ireland and the Republic of Ireland regarding this discussion.
Mr Byrne said Taoiseach Michéal Martin worked closely with Prime Minister Arlene Foster, Deputy Prime Minister Michelle O’Neill and Prime Minister Boris Johnson.
“I think you will find that it escalates even more over the next few days,” he said.
“I think it’s really important because we are in a public health crisis.
“NI is ahead of the Republic of Ireland at the moment, but it’s clear that our numbers trajectory isn’t great either.
“This island must be treated as a single epidemiological unit at the moment, our public health concerns are so far more important than any other consideration. ”
Mr Byrne said Ireland’s advice on essential travel was clear: ‘If you’re in Dundalk we don’t want you to go to Castleblaney and we don’t want you to go to Newry and obviously the advice is worth every way.
“If you’re in Donegal don’t go to Derry, but don’t go to Leitrim either.
QUB virologist Dr Lindsay Broadbent said the “huge jump” in Covid-19 hospital admissions over the past week “means it’s time to do something”.
“This is what is really worrying. We can keep an eye on the number of cases, that’s part of that, ”she told BBC Radio Ulster’s Stephen Raney show.
“The most important thing to watch out for is the number of people hospitalized. Admission to hospital is what follows this increase in deaths, and that’s really what we’re trying to avoid. “
