It is an unfortunate old cliche that people tend to go to hospitals to get sick. And while they usually go to the hospital in the first place because they are sick, the fact of the matter is that tens of thousands of people die every year, in spite of recovering from their original issues, just because of the environment that most hospitals are. For the most part, a hospital is a place where all sorts of different germs have been breeding for hundreds, or even thousands, of their generations. And for all of the effort that we humans have put into combating these diseases through antibiotics and cleaning procedures, they are still pervasive. And of course, we are entirely to blame for this, in spite of all that we pretend to be doing.
Most hospitals have cleaning procedures that are not routinely followed by the staff. While it is clearly outlined that most bacteria and viruses are killed by bleach, in a lot of cases bleach is not used in the cleaning of a patient’s room and the equipment that is native to that room. This means that over time, a lot of things that you might not think about (such as the rails of the bed, and the vertical bar that holds up the IV bag of medicine) can end up being covered with germs.
And unfortunately for the poor folks who are staying in the hospitals, these are not just simple, easy to shrug off kinds of germs, either. These are actually highly evolved strains of infection that are known as super bugs. And not only are they evolved to be able to attack the human immune system very effectively. They have also generally been conditioned to be highly resistant to antibiotic intervention. So once a person gets sick with a super bug, they tend not to get better on their own, or even if they take an antibiotic. They just die.
