I didn't say you were currently at capacity. I said if the UK continues at its current trajectory, your healthcare system will hit capacity. Going back to the
article that
@UKMikey posted, it appears that the infection rate is worse than the "worst-case scenario". The UK probably isn't as screwed as the US is at this very moment, but it's on its way there.
It's also worth understanding that capacity isn't measured in terms of space, it's measured in terms of staffing. I'm sure the UK has more than enough beds available, most places have more than enough beds. The problem is that they don't have the specifically trained staff, especially when it comes to ICU care. You can't just throw any nurse in the ICU and expect them to provide a level of meaningful care. You can't just magically create medical staff either, almost all of it requires a significant amount of training, even down to the person who cleans the rooms.
I also agree that many people will die from not being able to get procedures that they need now due to restrictions put in place by the health system. But that's not the fault of the health system, it's the fault of people not taking COVID seriously and doing what they should be doing to reduce the infection rate. If COVID precautions were taken seriously and people got it out of their heads that it's no big deal, then there wouldn't be an issue.
