The Health Service Executive is to send medical personnel to nursing homes where 38 clusters of Covid-19 infections have been identified.
The medical personnel are being deployed in crisis response teams and their task will be to assist and advise staff on how best to contain and deal with infections.
According to the Health Protection Surveillance Centre, a cluster is three or more cases in an institution within a 72-hour period.
Yesterday, it was announced that 22 more people with Covid-19 have died in the Republic - the highest daily number since the pandemic reached Ireland.
