Dr Tony Holohan said: "Today we are reporting a further 90 deaths, bringing our cumulative total of lives lost to Covid-19 to more than 3,000 in Ireland. This highly infectious disease is having a severe impact on the most vulnerable in our society and we must continue the good work we are doing to suppress it.
“The decline in daily incidence of Covid-19 has begun, however the volume of disease in our communities remains very high. To date we have reported 96,000 cases in January 2021, which has already passed the total of 93,500 cases reported in 2020.
"Indeed, public health doctors in the Midlands reported a total of 4,000 cases in the first 8 months of 2020 and another 4,000 cases in the first four weeks of 2021."
The latest figures come as it was announced Ireland's Level 5 lockdown will be extended until March 5.
Schools are to reopen on a phased basis from February and mandatory quarantine is to be brought in for passengers coming in from overseas.
Taoiseach Micheal Martin made the announcement this afternoon, saying the restrictions are being extended "with a view to crushing the numbers of those contracting the disease.
"The message is stay at home, do not travel do not make any journeys outside of your 5km unless you absolutely have to," he said.
The Taoiseach said that we "must reduce" the numbers in hospital and ICU with Covid-19.
"Our hospitals are under enormous pressure," he said.
Mr Martin added: "The current Level 5 restrictions are having a very positive effect on the country.
"I would like to thank everyone for your efforts to date."
