The Acting Chief Medical Officer has urged everyone to cut the number of social contacts they have by half.
He over the last two weeks alone Ireland has seen somewhere between 750 and 1,000 cases of community transmission of coronavirus.
Amid a surge in new COVID-19 cases, the Government this evening confirmed Dublin will face a range of restrictions for the next three weeks.
However, coronavirus figures continue to rise in other parts of the country as well.
Latest HSPC figures show that over the past 14 days Louth sits on just under 92 cases per 100,000 population - two weeks ago that was just 14.
📈80 was the incidence rate benchmark effectively for bringing in #LOKdown, which was basically Level 4.
Four counties on similar or higher - Dublin, Waterford, Leitrim and Louth.
Counties for concern are Wicklow, Offaly, Kildare, Limerick, Donegal and Longford. All 50+. pic.twitter.com/nT3Ms1VFTI— Ben Finnegan (@_BenFinnegan) September 18, 2020
Waterford and Leitrim are on 81 per 100,000 - although Leitrim's low population has contributed to the figure being so high.
Other counties with rates above 60 are Offaly and Wicklow, while Dublin has now reached more than 114 per 100,000.
Speaking this evening, Dr Glynn said it's up to everyone to take individual actions "now" to reduce the spread of the virus.
He said: "As a rule of thumb, plan to see half the number of people next week as you saw last week.
"If we all cut our social contacts by half, we can cut the reproductive rate of this virus by half.
"Our priorities over the next three weeks must be to slow the spread of this virus, so our health service can continue and people get the vital care that they need for other illnesses; so that the successful resumption of education for our children can continue; and so that those who are most vulnerable in our society are protected."
He urged people to prioritise who they say, and that meeting fewer people means fewer opportunities for the virus to spread.
