The law enacting mandatory hotel quarantine for arrivals from specified countries has been signed by the president, but the system will not be active until the end of this week or early next week.

While the quarantine mechanisms have been "largely finalised", a grace period is needed to allow those who are due to fly into Ireland this week to book their places in the facilities.
