The HSE’s executive director Paul Reid has acknowledged that there could be a spike in Covid cases after Christmas.
That was “a legitimate concern” he told Newstalk Breakfast.
If the public works with the authorities then lockdown should not be inevitable in January.
“We’re in a strong position going in.” Ireland has one of the strongest positions in Europe with regard to the level of Covid cases, he said.
Ireland was in this position because of the behaviour of the public.
This period could be used now to further strengthen that position and allow for a safe Christmas.
Mr Reid said there was “a staircase of risks” and that every step of the process was a risk.
What the Government had to do was to “take a whole lot of advice,” from Nphet, from the HSE, from the CSO and from economic data.
“They have to take a balanced set of risks, they have to consider all of the input and then decide.”
