Justice Minister Helen McEntee confirmed on Friday morning that the new testing regime, due to commence on Friday, had been postponed.
“I think people will appreciate that a number of departments are involved here,” Ms McEntee said.
“It takes time, where you have to engage and make sure that the regulations are correct,” she told RTE radio.
“This is simply procedural. It’s not that there has been a change at all. There just is a little bit longer time needed between departments to finalise these, so it’s not about Government flip-flopping or changing direction.
“We have to change direction sometimes because of the nature of this pandemic. Everybody is doing their best here and everything we have done has been with the intention of keeping people safe.”
Na quinta feira, chief medical officer Dr Tony Holohan said: “We are beginning to see stabilisation in a range of key indicators of incidence of Covid-19.
“While this progress is very welcome, the level of disease in the community is still a concern.
“Stabilisation is happening at too high a level. The current high incidence is driven by the Delta variant, que, coupled with the presence of the Omicron variant, means that the trajectory of the disease remains uncertain.”
Na quinta à noite, a Bill that would put the potential introduction of mandatory hotel quarantine on a legal footing passed all stages in the Dail.
It is set to be debated and passed by the Seanad later on Friday.
