Well, let's not get cocky. I know some folks right here in the US who contracted a multiple drug resistant infection while in the hospital. I know others who contracted some other less serious bugs. Good handwashing procedures don't cost a lot of money to carry out. Just discipline. That would help a lot.
The bad, bad bugs are most assuredly here in the USA, also: Deadly and utterly immune to all anti-biotics. One of my patients died from one several weeks ago.
As for the UK, new hospital building by and large ceased after 1948 when the system was socialized. It is like some kind of time capsule over there with Victorian era open wards in filth.
Same thing in Canada, hardly anything built after 1975, when the socialists "cured" heathcare. Like looking at 1957 cars driving around Havana.
