In a statement issued by the Department of Health, they stated that two females and two males from the western part of the country have been diagnosed, bringing the total here up to six.
Dr. Tony Holohan, Chief Medical Officer with the Department of Health, said:
"Tonight we can confirm there are now six cases of COVID-19 in Ireland. Contact tracing is underway for these four new cases."
The patients are all associated with travel from the same affected area in Northern Italy.
Dr. Ronan Glynn, Deputy Chief Medical Officer, Department of Health, said it is important to remember that the number of affected people in Ireland is still low.
"There is still no evidence of widespread or sustained community transmission in Ireland, as seen in some other EU countries.
"While we now have six confirmed cases of COVID-19 in Ireland, we continue our containment efforts, central to which is that the public know what to do in the event they have symptoms," he said.
