Restrictions for counties Laois, Offaly and Kildare have been in place since midnight as part of the Government's response to a spike in cases of Covid-19.
Residents will face restrictions on their movements for the next two weeks but will be allowed to travel for farming and certain family reasons.
There will be limits on movement meaning people should only travel out of their county for certain reasons such as childcare or looking after vulnerable relatives.
People can also travel outside those counties for work, but only in cases where they cannot work from home. Since last night, cafés, restaurants and bars have been closed, and there will be no sporting events or matches.
