Meanwhile, a total of 2,676 people contracted Covid-19 in hospital, new figures from the Health Service Executive have revealed.
The HSE said that there is extensive testing of people on admission to hospital and while in hospital, to help find people with infection as quickly as possible, so that measures can be taken to reduce the risk of spread of infection to others.
The figures are from 21 June last year, to 28 February this year and were supplied to Peadar Tobin TD, Leader of Aontú, under a parliamentary question.
The HSE said that the collection of data on hospital-acquired Covid-19 infection started in June last year and March data for this year is still being validated.
It said it uses a standard definition of hospital-acquired Covid-19 and it excludes most cases of community acquired Covid-19 and includes most cases relating to inpatients with hospital-acquired Covid-19.
