There have been 147 more cases of COVID-19 reported in Ireland.
The latest figures also show there have been no further deaths here.
There has been a total of 28,116 confirmed cases of COVID-19 and 1,777 related deaths in Ireland.
Over the past 14 days, 1,354 cases have been notified - giving a 14-day incidence of 28.4 per 100,000 population.
Of these cases, the median age is 32 with 72% of cases in those under the age of 45.
Of the cases notified on Monday:
- 80 are men / 67 are women
- 71% are under 45 years of age
- 60 are confirmed to be associated with outbreaks or are close contacts of a confirmed case
- 14 cases have been identified as community transmission
Some 73 cases are in Dublin, 17 in Kildare, 12 in Offaly, 11 in Wicklow, nine in Limerick and the remaining 25 cases are in Carlow, Clare, Cork, Donegal, Galway, Laois, Louth, Meath, Monaghan, Tipperary and Wexford.
Dr Ronan Glynn, Acting Chief Medical Officer, said: "Evidence from the ECDC and international experience to date suggests that children do not commonly transmit COVID-19 to other children or adults in school settings.
"Internationally, where schools have been re-opened, schools have not been a significant driver of community transmission.
"We all have a role to play in keeping this virus at low levels - this is key to protecting our education system over the coming weeks."
On figures in the capital, he said: "It's not that there's a major problem, I'm not sounding any major alarm here for Dublin.
"But we have seen an increase in cases in Dublin, along with the rest of the country, but particularity in Dublin now over the last number of days.
"So again this evening there's 73 cases in Dublin, so I suppose it's just something that we're watching closely."
One-in-three cases in Dublin is community transmission, which is slightly higher than what is being seen nationally.
Dr Cillian DeGascun, director of the National Virus Reference Laboratory, said: "We know that children can get multiple respiratory tract infections over the winter period and as a result could require repeated swab tests.
"Therefore, NPHET, HSE and NVRL are continuing to assess alternative testing methods for children."
Dr Siobhán Ni Bhriain, consultant psychiatrist and Integrated Care Lead HSE, added: "There will be cases in school aged children just as there have been throughout the pandemic.
"When these occur, our public health teams will lead the response to limit further transmission - as has been the case in other settings throughout this pandemic."
And Dr Mary Favier, president of the Irish College of General Practitioners, said: "Parents should remain vigilant around symptoms and keep their children isolated at home if they are experiencing fever, cough, shortness of breath, flu like symptoms, loss of taste or smell.
"Parents should also remain aware of asymptomatic transmission - like some adults, children may not present symptoms but can still carry the virus.
"If you have vulnerable people in your limited network, ensure physical distancing is adhered to and encourage regular hand washing habits with your child".
