The Department of Health has reported 1,025 new cases of Covid-19 and two further deaths related to the disease.
The UK variant of COVID-19 has also been detected in the country, with NPHET urging people to stay at home, avoid social contact and avoid all forms of non-essential travel.
Commenting on the new strain of the virus, Dr Tony Holohan said that further testing in the coming days and weeks will establish the extent to which it is present here.
“It is particularly important that those who have arrived from the UK strictly self-isolate for a full 14 days following arrival,” he said.
“They should not interact with others, visit others, socialise or go shopping. The HSE is making arrangements to test recent arrivals from the UK. Full details of advice and procedures are available at www.hse.ie.”
There has now been a total of 84,098 confirmed cases of COVID-19 in the Republic of Ireland and 2,194 COVID-19 related deaths.
