There are a total of 237 cases of the Delta Covid-19 variant on the island of Ireland.
The HSE's latest update told us that the Republic had 126 cases - while 111 were confirmed in the north as of Sunday.
It comes on a day where UK Primer Minister Boris Johnson is expected to announce a delay to the planned reopening of the UK.
Having initially indicated that 'all restrictions' would be lifted on June 21, Johnson is set to push that back by at least four weeks when he addressed his people at 6pm.
Meanwhile, our Minister for Foreign Affairs Simon Coveney has warned that tighter travel restrictions between Ireland and the UK may be needed to stop the spread of the Delta variant here.
The Covid-19 strain, which was first identified in India, has put huge concerns on plans to end lockdown in the UK due to its high level of transmission.
Our closest neighbours have seen a surge in hospitalisations in recent weeks as they races to vaccinate the rest of the population before the virus spreads further.
And concerns have been expressed about how the variant may affect Ireland's reopening plans.
On RTÉ's This Week, Mr Coveney spoke about the more infectious Delta variant of Covid-19 in the UK.
"The numbers are concerning and we need to do what we can within reason to do what we can to protect people here," he said.
"I don't want to announce anything today but we are looking at this seriously."
