Senior health officials are concerned about the increase in the number of Covid-19 patients being admitted to the ICU.
47 patients have been in intensive care with the virus.
The country's top health officials will meet this morning to discuss the increase, as well as other worrying trends such as the number of clusters in nursing homes, the rise in community transmission and the spread among health workers.
There are now 1,819 confirmed cases here, resulting in 19 deaths.
Deputy Chief Medical Officer Dr Ronan Glynn says we won't know if the measures put in place are working until next week at the earliest.
"We're at the earliest stage inn terms of expecting to see positives effects from those measures.
"We'd be looking forward into next week and the week after to see first of all if the measures we've taken have had an effect, but then crucially it's to sustain that over time - it's not a case of a very short sharp beneficial effect over a day or two days."
