Am in Germany. DS1 is in secondary school. Masks in all areas of school except classrooms, where they are optional. I went to get him early from his class the other day and not one pupil nor the teacher in his class was wearing one.
To be honest the UK stuff we are hearing here sounds totally random and baffling. None of it makes any sense. We had our lockdown, but it was never as draconian, and it eased fairly quickly.
I don't know all the ins and outs of German healthcare, but everything is much more spread out and not centralised. For example I've had loads of ultrasound scans since coming here. My GP has checked my thyroid with her ultrasound machine. My gynecologist has done all my pregnancy scans with hers, plus checked my kidneys during pregnancy when I complained of aches there. She has two, both of them can do fancy 3D scanning. I was sent to another specialist gynecologist for a more detailed scan where I could have had amniocentesis. I had a different GP check my kidneys on one because I had repeated UTIs and they were concerned. I think DH had one when he broke his foot as well, but I can't remember.
In the UK for all of these instances I'd have had to be referred to radiology at the local hospital. That would have taken longer and IME a lot of the time you simply don't get the scan. The only scans I've had in the UK were the routine ones during pregnancy and then when I was hospitalised with a severe UTI I got one then, (This is probably what rendered my kidneys a bit dodgy in the first place, TBH) but any time I saw my GP for anything urinary related after that I didn't get referred for a scan, even when I was having pain in the kidney area. Here it seems to be "Well we have the machine here, may as well use it".
I would imagine it is much the same as testing. And while all the doctors/labs etc are private, there are plenty of them and they aren't trying to operate centrally, they just claim back their costs from the patient's health insurance. I don't think they can claim for the purchase of the ultrasound machine, but they can claim for each justified use of it, which goes towards offsetting the purchase cost. I know that during pregnancy, my health insurance paid for 3 scans, but my gynecologist just scanned me every time anyway - I must have had about 12.
The only thing I don't like is that if you need an MRI/operation/etc, rather than just being referred to whichever specialist has a space on their waiting list you have to phone around all the local places and find somebody who can fit you in and I find this very stressful and confusing.
With covid testing though it's been quite straightforward. I haven't had a test but from friends who have, you just call your GP, they tell you which test centre to go to and you go there.
