Eleven new Covid-19 clusters have been identified in locations across the North West in the past week, according to the latest HPSC report.
There are now 28 known outbreaks in specific locations in the region.
Five of those clusters are in nursing homes – an increase on the three known clusters the previous week.
Five more clusters were also reported in local community hospitals/long-stay units, bringing the total to seven. There are also five outbreaks in residential institutions in the north west.
The other outbreaks have been identified in private homes (5), in extended families (2) and two clusters are travel-related.
A cluster is defined as three or more confirmed cases of coronavirus in one location within a 72-hour period.
The latest update comes as increased testing continues in Irish nursing home settings. HSE chief Paul Reid has confirmed plans are being made to ramp up testing for Covid-19 to 100,000 tests a week.
Meanwhile, the HSE is supporting 425 long term residential care facilities affected by Covid-19, with HSE staff being redeployed to some of the worst private nursing homes.
