I was watching the "maternity" episode of "house" season one and house talks about these superbugs - extremely resistent pathogens created by over-prescription of powerful drugs and wide-spread exitence of 'anti-bacterial soaps in every washroom'. I know house isn't really the place to get your medical knowledge, but still the question is a real one. If a pathogen is not completely eradicated, we only only making it stronger - and worse for us. This can cause the disease caused by such pathogens to increase inseverity and less responsive to treatment while making the pathogens more resistent and harder to combat. The only solution would be even stronger drugs - how is this arms race kept under control. Most sugerbugs would fold under some sufficiently powerful drug, but what is some of them evolve into nigh untreatable super-epidemics? What steps are taken in this regard?
