5,483 new cases of Covid-19 have been reported this evening - the highest figure since January 10th.
The Chief Medical Officer says it's also one of the highest ever daily case counts.
Dr Tony Holohan says there's been a very significant increase in cases in almost all age-groups.
549 Covid patients are in hospital, down six from yesterday, while the ICU figure is down one to 96.
However a backlog in data could be causing a surge of reported cases.
NPHET is recommending people who frequently go to nightclubs, bars or restaurants take an antigen test twice a week.
The Chief Medical Officer has also asked the Government to consider extending the use of Covid-19 certs beyond the hospitality industry.
The cabinet will consider their recommendations on Tuesday.
Meanwhile, the Irish Prison Service says it's managing two outbreaks of Covid-19, which has seen 37 prisoners test positive for the virus.
4 prisoners at Cloverhill have tested positive, while 33 inmates have tested positive at the Midlands Prison.
The service says arrangements are being made for the mass testing of staff and prisoners in Cloverhill Prison on Sunday and Monday.
To date, 15 outbreaks have occurred in jails around the country.
