The number of people in hospital with COVID-19 has passed 700, latest official figures show.
As of 8am on Tuesday there were 703 confirmed cases in hospital, with 32 in ICU.
That is an increase of 47 people on Monday's figure - and is up from 464 just 14 days ago.
It comes amid concerns that socialising over Christmas could lead to an increase in cases.
The Chief Medical Officer Professor Breda Smyth has said people should be wearing masks again on public transport.
Prof Smyth also said that people should be masking up in crowded and confined spaces.
"COVID is still with us, and we are not wearing our masks," she said on Monday.

"Your mask should fit well and cover your nose. Don't touch it or pull it down over your chin.
"Masking up means that you are less likely to transmit infectious droplets to others.
"Remember: wearing a mask isn't just for you - it's for everyone.
"So please, let's all mask up for each other," she added.
The Government is said to be considering re-introducing a mask mandate.
