Explain how the excessive or inappropriate use of antibiotics poses a health hazard for a human population.?

Question

What about antibacterial hand soaps and other products?

Answer 1

If it were simply a matter of adverse reactions to antibiotics (which can happen in as many as one in six people) there would be no real problem, except to those affected.

But killing germs willy-nilly isn't a good idea. Most of them are either useful or harmless. And it takes not just one or two, but a significant number of the pathogenic strains to cause infection. Killing germs indiscriminately will, by its very nature, kill the ones that are easier to kill. That leaves the tough ones to multiply and become predominant.

Antibacterial hand soaps are not a major problem, because they aren't that effective, despite ads to the contrary, but even they are more than just a little silly. It's perfectly appropriate to wash with plain soap and water, washing off the germs, rather than using something to kill the germs. The end result is the same, decreasing the colony count on your hands. That may not apply to the surgical scrub the surgeons do before they operate, but then the risk:benefit ratio is different in that circumstance.

Answer 2

Sometimes the body just needs a chance to fight off an infection by itself, thereby becoming immune to that particular infection. When we overuse antibiotics, germs become used to them, and we end up with "superbugs" like MRSA (Methicillin Resistant Stapholococcus Aureous). Even antibacterial handsoaps can be overused. Our skin has a natural "flora" (good germs), and when we overuse soaps, we not only kill the bacteria on our hands, we kill the good germs, too.

Answer 3

Because bacteria and other nasties that antibiotics are used for have been shown to develp resistance to antibiotics which means that the antibiotics don't work anymore and we have to find new ways of defeating them as they get stronger.  Some day they may get be resistant to so many things that we won't be able to kill them.
