There have been 18,904 further confirmed cases of COVID-19 in Ireland.
As of 8.00am on Thursday, 1,011 patients are hospitalised with the virus - 92 of whom are in ICU.
The five-day moving average of cases has dropped further to 20,879.
Chief Medical Officer Dr Tony Holohan says people should be aware of new advice around masks.
"It is important to note that the latest public health advice around self-isolation and restriction of movement places an increased emphasis on the use by cases and close contacts of higher-grade face masks, as opposed to cloth masks.
"Other protective measures including strict limiting of social contacts are also advised for the full 10 days following a confirmed COVID-19 infection or close contact.
"These combined measures are intended to offset any increase in risk of transmission that may result from the reduction and or removal of the requirement to self-isolate or restrict movements."
Dr Holohan says the changes mean medical-grade or FFP2 masks should be used by:
- Anyone 13 years and older who is a confirmed case, a close contact or who has symptoms suggestive of COVID-19
- Over-60s and vulnerable people of all ages in indoor or crowded outdoor places
- Anyone visiting a healthcare setting or when visiting those who are vulnerable to COVID-19 in any setting
He says: "Masks can play a key role in reducing transmission of COVID-19 if made correctly, well fitted and worn properly: that is they cover the nose, mouth and chin.
"By layering up on the basic public health measures, including vaccination, we can reduce the spread of COVID-19 and continue to protect ourselves and our loved ones from infection.
"Continue to practise social distancing and good hand hygiene, work from home unless necessary to attend, avoid crowds and ensure indoor spaces and public transport are ventilated".
