Dr Holohan said Ireland is experiencing a rapid increase in the incidence of the disease in communities.
He said that cases are increasing in 22 out of 26 counties, with the greatest majority of cases occurring in people who have not yet been fully vaccinated.
A further 1,173 confirmed cases of Covid-19 were notified on Friday.

As of this morning there were 79 Covid-positive patients in hospital, with 23 in intensive care.
“The current trajectory of the highly transmissible Delta variant across the country means that unvaccinated people are at high risk of contracting Covid-19, with just over 50 per cent of today’s cases aged between 19 to 34-years-old,” Dr Holohan said.
“We need those who are waiting for full vaccination to take every precaution this weekend and adhere strongly to the public health advice as they await their vaccines – limiting social contacts, meeting outdoors, staying two metres apart, wearing masks and avoiding international travel.
“If you are experiencing symptoms of cold and flu – headache, sore throat, runny nose, please let your close contacts know, stay at home and get tested as soon as possible for Covid-19.
We are seeing very rapid increases in incidence in 16-18, 19-24 and 25-34 year olds. The rise in those aged 16-18 years is exceptional. Please do everything you can to stay safe, and to encourage and support those around you to stay safe too. pic.twitter.com/drofQphJVn

“From today, 25-29 year olds can register for their vaccine on the HSE website and I would strongly encourage this age group to do so by visiting HSE.ie.”
