Fianna Fáil TD Cathal Crowe said he was "appalled" to see many people not wearing masks when he was on the train recently. "It's a 'two fingers' to society!
It's an affront to our frontline health workers!", he told the Dáil during a debate on Covid-19 and the latest measures to address the crisis.
The Clare TD called on more people to wear masks. The Dáil also heard an appeal from Minister of State at the Department of Health Mary Butler.
She urged those who have not been vaccinated "to come forward" and "speak to a health professional" about their concerns. Sinn Féin's David Cullinane said his party will not support Covid emergency powers where there is "no involvement of the opposition".
