What happened even a few years ago in hospitals is different than what happens now because of the super bug crisis. Second of all, this was a surgical floor. What happens in surgical wards or in ICUs is bound to be different than A&E or general medical floors. Lamuella showed that being that strict about contact is the policy in this country. If the US isn't taking the crisis as seriously, that is a huge concern.
The last time I had to visit a hospital in the US was an ICU to see my dad in 2007. It was a huge change from visiting him in an ICU in 1998. There were no curtains (there were blinds inside glass partitions. There was a lot more hand sanitiser. I am sure things have changed even since then.
I know that some countries don't allow the temperature to go above a certain level in the hospitals, so it feels like you're in very intense air conditioning. Where there are curtains in places like A&E here, they are disposable and dated, and changed regularly. We visited Chelsea and Westminster yesterday for some testing, and there was literally automatic hand sanitiser stations every 15 feet or so. That's a change from the same hospital in 2008 where there were just little pump hand sanitisers at the entrance of every unit and at every patient door.
