There have been no additional deaths of people with Covid-19 reported in Ireland in the last 24 hours.
The Department of Health has been notified of 18 new cases of the coronavirus.
The total number of deaths associated with Covid-19 in Ireland stands at 1,706, while there have been 25,321 confirmed cases here.
Chief Medical Officer Dr Tony Holohan said that there have been no admissions to ICU since 9 June.
He said there are 78 confirmed cases still in hospital, with two admissions to hospital within last 24 hours.
He said there have been 471 clusters in residential care facilities, up six since last Thursday's briefing.
He said five of these clusters come from the nursing home sector, bringing the total there to 256.
He said 297 of the 471 clusters are now closed, which means "they haven't had an incident case in the past 28 days".
He said 174 of the 256 clusters in respect of nursing homes are also closed.
There has been no increase in number of clusters or in the number of cases in the Roma community, the Traveller community, in direct provision or among the homeless, he said.
He said there has been one additional report of a cluster associated with meat factories, and 11 additional cases, bringing the total number of cases in meat factories to 1,102.
Dr Tony Holohan said the latest survey carried out by Amárach has found that 61% of those questioned
feel it is likely that Ireland will experience a second wave of Covid-19.
When questioned about face masks, 34% of people surveyed said they are now wearing a face mask. Dr Holohan said they will keep an eye on that figure.
In relation to social distancing in classrooms, Dr Holohan said it is not just about one or two metres of distance. There is an entire package of advice, he said, which takes into account the environment, the size of the classroom and the length of the school day.
Deputy Chief Medical Officer Dr Ronan Glynn added that the factors that might contribute to risk, which will also be taken into consideration, include the activities students engage in, the extent to which different classes mix, the extent to which hygiene and hand-washing facilities are available and the extent to which guidance is available for parents and teachers if a student is sick, so a student knows not to come to school if they are unwell.
Dr Glynn said "all of that has to play into the guidance".
He said: "It's too simple really to break it down to say it's one metre or two metres, that's a part of the consideration and will be part of the consideration of the guidance and ultimately part of the decision-making of the Department of Education, but it's too early to say and it's not for us to say".
He said they are not recommending the use of face masks for children under the age of 13.
Dr Holohan presented figures to the briefing which go up to the beginning of last week, and show an increased number of people are driving rather than taking public transport.
He said the trend is that there has not been a very significant return to public transport.
Dr Holohan said they are giving ongoing consideration about contact with grandparents, and whether
grandparents can mind children in their homes.
In relation to cancer screening, Dr Glynn said there are specific considerations to be taken into account and it is too simplistic to compare the recommencement of a cancer screening programme with any other
sector of society.
Dr Siobhán Ní Bhriain, Consultant Psychiatrist and HSE Integrated Care Lead, said there is not a specific date set for the recommencement of cancer screening programmes yet.
Dr Holohan has said he believes that Ireland has been "comprehensive" in terms of its mortality reporting
and said "that all the data that we have, we have made available".
He was responding to a question about a survey which claimed Ireland was the seventh worst in the world for Covid-19 deaths per million.
He said that Ireland has reported deaths in line with the WHO and the ECDC guidance, all lab-confirmed cases and all probable tests.
He said any time there has been a death and a positive laboratory test, they report that and they also report when there is not a positive test but a GP believes there is an association and certified the death as having an association with the virus.
He said many countries do not report those two things.
Dr Holohan said they also report deaths irrespective of where they occur - in community settings, nursing homes or residential care facilities, or hospitals.
Around 80% of cases of Covid-19 will be a mild to moderate illness, close to 14% have severe disease and around 6% are critical.
Generally, you need to be 15 minutes or more in the vicinity of an infected person and within two metres of them, to be considered at-risk, or a close contact.
As of midnight on Saturday, 13 June, 57% of Covid-19 cases were in females, while 43% were in males.
The median age of confirmed cases is 48 years old.
The HPSC data shows that 3,278 cases - 13% of all cases - have been hospitalised, and of those hospitalised, 417 have been admitted to ICU.
8,170 cases are associated with healthcare workers.
Dublin has had the highest number of confirmed cases at 12,213 (48% of all cases), followed by Cork with 1,533 cases, and Kildare with 1,434 cases (6%).
Of those for whom the transmission status is known, community transmission accounts for 37%, close contact with a confirmed case accounts for 60% and travel abroad accounts for 2%.
In Northern Ireland, no new deaths from Covid-19 have been reported in the last 24 hours, marking the first time in more than three months that the island of Ireland has seen no coronavirus-related fatalities.
The fact has been welcomed by Northern Ireland's Deputy First Minister Michelle O'Neill, who said in a statement that the progress is a boost for the work and sacrifices being made at every level.
In total, there have been 541 recorded hospital deaths in relation to the coronavirus there.
There are four new confirmed cases in Northern Ireland, bringing the total number of confirmed cases there to 4,852.
