Chief medical officer at the Department of Health in Ireland, Dr Tony Holohan, has said there is no reason to cancel the St Patrick's Day parade in Dublin, which attracts hundreds of thousands of tourists from around the world.
Speaking at a press briefing in Dublin on Wednesday evening, he said:
"As things stand and on the basis of our assessment, we see no implications for the St Patrick's Day parade."
It comes as Northern Ireland remains in "containment phase" in relation to coronavirus despite two new cases indicated.
The region's health minister Robin Swann said the development showed that systems in place are working.
The two further presumptive positive results for Covid-19 brings the total in Northern Ireland to three since testing began.
The two cases are not connected. One recently travelled from northern Italy.
The other had recent contact with a person elsewhere in the UK who has tested positive for coronavirus, health officials said.
The latest positive test results have been sent to Public Health England laboratories for verification.
Health Minister Robin Swann said both patients are adults and are receiving appropriate care.
The minister said Public Health Agency personnel are "working rapidly" to establish contacts they may have had to prevent further spread.
"As I have said from the beginning, it is a matter of when not if we receive positive cases here in Northern Ireland," he said.
"In regards to how the two additional cases have come forward, I think it has shown confidence in the systems we have in place and they have worked yet again.
"I would stress that Northern Ireland remains in containment phase."
