There have been no further deaths reported from COVID-19 in Ireland.
The latest figures show there were 18 new cases here on Monday.
The death toll remains at 1,706, while the number of cases now stands at 25,321.
There are 23 people remaining in Intensive Care, with 78 people in hospital.
It comes as over 5,000 people are to take part in a study aimed at finding out how many of us have had the virus.
The study will take blood samples from thousands of people in Dublin and in Sligo to see if they have developed antibodies for the virus.
The two counties were chosen as representative of parts of the country with the highest and lowest levels of transmission.
Participants will be asked to take part in a phone interview before providing a blood sample at a local centre.
People will be given their individual results when they become available - and anybody who's developed COVID-19 antibodies will be asked to take part in a follow-up study.
The antibody test indicates whether a person was recently infected with the virus – even if they had only mild symptoms or if they were asymptomatic.
The study aims to examine how long antibodies last and what protection they offer against the virus.
