There have been 1,432 further cases of COVID-19 in Ireland.
Latest available figures show 272 people are hospitalised with the virus - of which 63 are in ICU.
There has been a total of 5,209 deaths related to COVID-19, which includes 30 newly-notified deaths in the past week.
The five-day moving average of cases has risen to 1,338.
Chief Medical Officer Dr Tony Holohan says incidence in schools has not seen an increase in transmission.
"We have been closely monitoring the incidence of COVID-19 and we are reassured that that the re-opening of schools has not led to an increase in transmission of COVID-19 amongst school-going children or more widely across the population.
"This is good news for students, parents and all those involved in the education of our children.
"As always, we will keep disease transmission in the population under review, but given the importance of education for our children we feel that now is the right time to evolve our approach to the public health management of COVID-19 in educational settings."
He was speaking as automatic close contact tracing in childcare facilities and primary schools is to be discontinued from Monday September 27th.
Other changes will see the end of testing of asymptomatic close contacts in childcare facilities and primary education.
Dr Holohan explains: "From Monday 27th September, we will change how we manage COVID-19 in our schools.
"Contact tracing of close contacts in childcare facilities and primary education and testing of asymptomatic close contacts in childcare facilities and primary education will no longer be necessary.
"Children aged 12 years or under, who are identified as close contacts in childcare, educational settings, special education settings or other non-household settings and who are asymptomatic will no longer be required to routinely restrict movements.
"Given the substantially higher risk of transmission in households as compared to any other setting, children aged 12 years or under, who are identified as household close contacts, will still be required to restrict movements and be tested, regardless of whether or not they have symptoms."
He adds: "Public health advice remains that any person, including children aged 12 years or under who displays symptoms consistent with COVID-19 should rapidly self-isolate and not attend school or to socialise until 48 hours after they are symptom free."
