I have spent the last decade working in hospitals and this has been the biggest problem. Infections. Things are becoming more and more resilient to antibiotics for several reasons.
I believe you mean "resistant" not "resilient".
Reason one: Incomplete use of medication. Many people feel better before the virus is completely destroyed by the antibiotic, so they do not finish it. This leaves some of the stronger cells there and they have information about that antibiotic. They are able to evolve to be resistant to it.
Viruses are NOT treatable with antibiotics, you must be treated with anti-virals. Bacterial infections are treated with antibiotics.
Reason two, as Cooking Goddess mentions, they are overused. Why on Earth are people in their mid-20's coming to the hospital with c. diff.? The good bacteria in their intestines are wiped out by antibiotics. Pro tip: sauerkraut and other fermented foods will help this.
Know what I do? I don't wash my hands (with the exception of being visibly soiled, leaving work to go home or before/during food prep and cooking). I have an immune system. I give it what it needs to work: Food and something to practice on.
I truly hope you are washing your hands in between patients, if not...you are the cause for nosocomial infections in the hospital setting.
I've said, modern medicine has it's place, but other things need to be looked at as well. Modern medicine can cure cancer (I believe numbers here can be skewed because to be "cured" you simply have to make it five years without it coming back), but we should be asking what is the cause, not what is the cure. Stop it BEFORE it happens. And before people lose their minds on me, I know some cancer is more hereditary, but I still believe that it is all preventable, especially with a good diet.
