Uusimaa is to see new restrictions on gatherings announced on Thursday and in force a week later, as the region centred on Helsinki struggles to deal with an upsurge in Covid cases.
The Regional Administrative Agency (Finnish acronym Avi) for Southern Finland is preparing the details of the restrictions because the capacity of hospitals to cope with their workload is currently under strain in the Helsinki and Uusimaa hospital district.
The region's Covid response co-ordination group has proposed new restrictions to try and slow the spread of the epidemic.
The Avi says it is evaluating the expert opinion and will decide the extent and severity of restrictions, but it is possible that they will limit capacity to a certain percentage of the full capacity.
However, event organisers that implement the Covid pass regime at the door can avoid having to restrict their events.
The new measures are expected to be announced on Thursday 18 November and to come into force a week later, on 25 November.
