The Northern Ireland Department of Health has said that 1,776 new cases of Covid-19 have been reported in the past 24 hours.
One further death has also been reported.
Today's number of new cases is more than three times the number of cases that were reported on the same day last week.
It is the first time the daily Covid-19 case number in Northern Ireland has topped 1,700 since January.
It comes after 537 new cases were reported yesterday, 1,402 cases were reported on Saturday and 1,380 on Friday.
There were 109 Covid-19 patients in hospitals in Northern Ireland today, including seven people in intensive care.
To date, 2,180,618 vaccines have been administered in Northern Ireland. Of these, 1,202,031 are first doses.
Deputy First Minister Michelle O'Neill said: "With over 1,700 cases today people are right to be concerned again.
"We all need to redouble our efforts in terms of social distancing, washing hands, following the public health advice and guidance at this time."
Earlier this month, the Stormont Executive agreed to ease restrictions further. This includes the reopening of live music settings and increased numbers of people permitted to socialise indoors.
Ministers are due to consider further relaxation of restrictions from 26 July.
Ms O'Neill stressed that the North would be taking a "cautious" approach to easing restrictions and criticised the approach of Boris Johnson's government to ease restrictions in England as "reckless".
Most restrictions were lifted in England today, in what has been dubbed "freedom day". Ms O'Neill said she was "quite disturbed" by some of the scenes from England.
"This isn't England, we have always set our own path throughout the pandemic and will continue to do so," she said.
"I would be quite disturbed by some of the imagery which I've witnessed in the last 24 hours - that includes people getting together whenever cases are clearly on the rise.
"Here in our own situation, cases are on the rise, hospitalisations are on the rise, so people need to be very, very careful in the time ahead.
"We will have an Executive meeting on Thursday, we will have an opportunity to discuss the current prevailing situation.
"We also expect to receive advice from the chief medical officer and the chief scientific adviser around can we proceed with the easements which we had previously announced but said we would ratify at this Thursdays' Executive.
"I am yet to see that information so I can't say definitively around what will happen next.
"It's very, very clear, and certainly the people I'm speaking to over the weekend, people are alarmed again. People are worried just about the rising cases so people need to be very, very careful to mind themselves and mind others around them as well."
Stormont ministers have stressed the importance of vaccination, as they urge all adults to come forward to get a jab.
At a mobile vaccination clinic outside a football ground last week, Health Minister Robin Swann said: "The current increase in Covid-19 infections in Northern Ireland means that all of us need to step up our efforts to fight the virus.
"Getting yourself vaccinated and encouraging your friends and family, specially younger people, to get the jab will help to protect us all. We're bringing the vaccine to every community - please don't delay in getting your jab."
