The Deputy Chief Medical Officer has appealed to parents not to see the return of the remaining primary school classes next Monday as a signal to return to work.
Dr Ronan Glynn also warned that if employers are asking people who do not need to go to work to return to work, they are putting all that has been gained at risk.
The National Public Health Emergency Team (NPHET) noted a slight increase in the seven-day average of Covid-19 cases in recent days.
It said it is concerned that any further increase in the mobility of people could make the situation worse. At 8pm last night, 341 Covid-19 patients were being treated in hospital, including 87 people in intensive care.
