Germany is debating a triage law today and here in France ICU units are approaching capacity limits. There’s a ‘plan blanc’ in our local hospital and many others.
The pressure on hospitals is still increasing with no sign of let up. It will take several weeks of decling case numbers to improve the situation in hospitals.
All that says no relaxing of measures for a month apart from the isolation time if the scientists agree on it.
I can’t see any change in policy on UK visitors in January. As I alluded above saving the French February ski holidays will be a priority not opening up to non-EU guests.
Your best indicator is ICU capacity, follow that. Overloaded to the point of triage for well over month on current numbers. ☹️
