It comes as Dr Denis McCauley, chairman of the Irish Medical Organisation's GP Committee, said the rising numbers of cases show that earlier public health measures did work.
He said: "It just shows the public health measures did work.
"The fact that we're dealing with a very infectious virus, that as soon as we take away the public health measures the rates start to go up significantly.
"So the public health measures work, we know that now - we've always known it, but we know it well".
And he said the question of mask wearing should now be between 'mandatory and manners'.
"Manners should really extend that - I think we should realise that... we are free, we're relatively free now.
"But I think we should respect those around us: if we're in an area where there are a number of people, that is crowded - particularly indoors - even outdoors, you should consider wearing a mask.
"I always sort of said 'until the end of March' anyway - but I think until we see the numbers beginning to go down".
