Ireland has the lowest 14-day incidence rate in the EU, according to Dr Tony Holohan.
The Chief Medical Officer was speaking after confirming another 270 cases of coronavirus in Ireland.
Five further deaths were also confirmed by the Department of Health.
And speaking after the announcement, the CMO emphasised that Ireland needs to keep up the hard work.
Dr Holohan said: "It is important to keep up the progress that we have achieved in recent weeks.
"Ireland now has the lowest 14-day incidence of COVID-19 in the EU according the latest ECDC figures and we need to hold firm to this position. As the country moves into Level 3, there is no room for complacency in our response to COVID-19.
"As more services reopen for business, remember to use the basic public health advice as a guide when organising your time.
"When you are out in shops and accessing services, try to avoid high risk situations and wear a face covering when social distancing is not possible on busy streets and crowded outdoor areas.
"When you come home from shopping or being outdoors, remember that washing your hands is your first priority. For those of us who cannot work from home, the wearing of a face covering is now advised when moving around busy indoor workplaces and in communal work areas. If you are planning to travel around your county, consider first whether it is absolutely necessary to travel.
"Your individual actions are vital to our national effort to suppress the transmission of this disease."
