There have been 763 new Covid-19 cases in Northern Ireland in the last 24-hour reporting period, the Department of Health announced, bringing the total to 23,878.
This includes the 6,394 new positive cases notified in the last seven days.
There were four deaths reported, taking the official toll to 606.
There are 201 patients with Covid-19 being treated in hospital, with 24 in intensive care.
Meanwhile, First Minister Arlene Foster has said she "respectfully disagrees" with an assessment by the British Medical Association in Northern Ireland (BMANI) that the restrictions introduced by the Stormont Executive this week are "too little, too late".
Dr Tom Black, a GP in Derry and chair of BMANI, said the association is "unanimous" in its view that more severe measures were required to dampen the spread of Covid-19.
The 14-day incidence rate for the Derry and Strabane Council area currently stands at just under 1,600 per 100,000.
He said "it is not good enough" for retail to remain open, for 25 people to be able to attend a wedding, or for gyms to remain open.
Speaking on RTÉ's News at One, Dr Black said restrictions similar to Level 4 measures imposed on three border counties in the Republic are what is required in the six counties.
He said Altnagelvin Hospital in Derry is under severe pressure with Covid-19 admissions and the impact on ICU beds.
He said the virus "embedded in the community", and a "big concern" is the hospital system in Northern Ireland having to deal with a doubling of inpatients every three to four days.
"That means that is it quadrupling every week, and the system will not cope with that sort of pressure."
Dr Black believes "extraordinary outbursts" of the virus in the Derry and Strabane area are as a result of complacency, and an increase in socialising.
"Everything went on as if we had defeated this virus," he said.

In response, Mrs Foster said: "I did hear the comments of Dr Tom Black from the BMA today. I respectfully disagree with him.
"I say that because not only do I have to look at the health outcomes in these issues, but of course the economic outcomes, the societal outcomes, the education of our young people.
"Therefore I think that what we came forward with was an action plan which has been blended to try and deal with all of those issues, not for one minute taking away from the huge challenge that lies in front of us all in relation to Covid-19."
