People in Dublin are being asked to limit household visitors to people from one other household only.
While Dubliners can - like the rest of the country - have a maximum of six visitors to their home, all other counties can have visitors from upwards of three households.
It's among a number of specific restrictions announced for the capital today, due to the surge in coronavirus cases.
While Dublin is at 'level two' of restrictions along with the rest of the country for the next three weeks, a series of extra measures will be in place for the capital.
It means the county has not yet moved to the significantly more restrictive 'level three' of coronavirus response.
'Wet pubs' will not be allowed reopen in Dublin yet, despite all pubs elsewhere in the country being allowed open again from Monday.
Pubs which serve food can continue to operate, however.
All other social and family gatherings in the capital are also being limited to people from two households only.
The Government said: "No more than two households should meet at any given time, and people should have a maximum of six visitors from one other household to their home.
"Socialising can continue at indoor or outdoor public venues, but only with people from their own household or one other household, and in groups of no more than six."
Dubliners are also being 'encouraged' to limit travel outside the county.
'Take particular care'
Tánaiste Leo Varadkar appealed directly to the people of Dublin to observe the restrictions, despite no large surge in the numbers of COVID-19 patients in hospitals or ICUs.
He said: "Perhaps the virus has become less deadly... perhaps we've just got better at treating it and shielding the vulnerable and the elderly.
"Perhaps, as some speculate, a second wave will be much less serious than the first - but, speaking as a Dubliner, I don't want us to take that chance.
"For the next few weeks, we're asking people of Dublin city and county to take particular care."
He urged people in Dublin to follow the 'four Ws':
- Not to welcome anymore than one other household into your home, and the same applies when socialising
- Wash your hands regularly
- Watch your distance and try to keep 2 metres apart from other people
- Wear a face covering wherever necessary
