People here are isolating for two weeks all the time. In Isle of Man you are then free from restrictions once completed and live normally. The care home persons children could visit and quarantine for two weeks and be free to visit, with no risk of death to anyone
By here, do you mean the UK? Because I can tell you, a lot of people aren't isolating properly. They come back from holiday, stay inside for 3-4 days (whilst still going to the shops for food etc), then decide it's over and start going to the park/work/school. These are people I know. Why do they get away with it? Because the UK government still don't have a proper system that ensures returning travellers quarantine for 2 weeks.
Someone correct me if I'm wrong, but I believe on the IoM you get sent to a government facility or you're monitored somehow, and can get a heavy fine if you try to break quarantine. I live in Germany, several times after flying back from a risk area the health authorities got in touch to check if I was isolating/testing properly.
When I last flew to the UK, no one checked my passenger locator form before getting on the flight. No one checked my form when I landed. No one checked I was staying inside during the isolation period.
It's like saying NZ or Australia shouldn't get the vaccine until Europe is fully vaccinated because they've managed the virus better than we did. Other countries shouldn't pay for the UK's incompetence.
