Ireland has been placed under similar lockdown measures to the ones imposed in the UK following three more coronavirus-related deaths.
Taoiseach Leo Varadkar said residents should stay home until at least 12 April unless they were buying groceries, getting brief exercise or making essential family visits.
Almost all shops will be told to close and all gathering outside of families will be banned.
Public transport will be available only to essential workers and nobody should travel beyond 2km (1.2 miles) from their homes for any reason, he added
Those over the age of 70 or with chronic diseases will be told to stay in their homes without exception over the period, which begins at midnight
Mr Varadkar said: "I'm appealing to every man, woman and child to make these sacrifices for the love of each other.
"Show that you care for your family and friends: Stay home
He added that there was little more the government could do in terms of restrictions.
The restrictions come after three more deaths thought to be as a result of COVID-19, the respiratory illness caused by coronavirus. One of the victims was a healthcare worker.
According to data compiled by US university Johns Hopkins, there are 2,121 coronavirus cases in Ireland, with 22 deaths recorded
