The best place to catch something is in a hospital, because it's full of sick people! Sounds crazy, but it's true. Sick people should not be crammed together in a stuffy building with a lot of other sick people, they should be somewhere with healthy people around them, some sunshine, and some fresh air.

However, the healthy people in society don't want the bother and the complex medical organizations that treat illness want everything in one place for obvious logistical and financial reasons.

And that's the irony of it all. Want to stay healthy? Try as best you can to stay out of the hospital. If you have to go there, try to make it a fairly brief stay. Some, of course, don't have that choice...and in fairness to the medical staff, they certainly do the best they can.
