There are seven new cases of the coronavirus in the Ireland.
Four men from the east of the country picked it up after travelling to northern Italy, where the illness is widespread.
Two women in the west got the illness from close contact with another confirmed case here.
And a man in the south picked it up from the community - he is being treated in Cork University Hospital.
The hospital has cancelled all outpatient appointments for tomorrow.
It said earlier this was due to "infection control issues".
While dialysis, chemotherapy, radiation treatments and infusions will proceed as planned.
Dr Tony Holohan, chief medical officer with the Department of Health, said: "Ireland remains in containment phase with just one case of community transmission.
"This is, however, a rapidly evolving situation. Public health doctors are working hard to ensure our containment measures are operating effectively.
"Most people who become infected with COVID-19 experience a mild illness and recover, but it can be more severe for some.
"However, this will need a national effort. Every individual needs to be aware of how to protect their own health and the health of others.
"The most important way they can do this is by following public health advice."
