The Government has rejected the National Public Health Emergency Team's (Nphet) recommendation to move Ireland to Level Five restrictions and instead has announced a move to Level Three.
The decision was taken after a meeting between the Chief Medical Officer Dr Tony Holohan and party leaders at Government buildings this afternoon.
In a television statement this evening Taoiseach Micheál Martin confirmed the new measures will take place from tomorrow night at midnight.
This follows a Cabinet decision this afternoon.
Earlier today following the announcement of 518 new cases, Chief Medical Officer Tony Holohan warned of the "significant and concerning deterioration" of the coronavirus situation nationally and said everything must be done to reduce the spread of the virus ahead of the winter months.
A move to level three entails stricter regulations for social gatherings and further restrictions for businesses.
It is expected that these stricter restrictions will be met with further enforcement.
Read on to see what the new measures mean.
