Comment: There have ALWAYS been

There have ALWAYS been problems with diseases being spread in hospitals. "Hospital staph", for instance, was the big deal in the mid 20th century. But it goes back as long as there have been hospitals, and before that as long as the sick and injured were taken to medical professionals for treatment, concentrating the risk.

Hospitals remain the place to go when you're seriously ill because centralized medical service remains so effective that the benefits FAR outweigh the small risks, while the hospital system is a feedback process constantly working on more effective ways to suppress such infections and other iatrogenic illnesses.
