The Disinfection of the Hands — Quantitative Aspects
In the early days of microbiology the Viennese gynecologist SEMMELWEIS (1847) was the first to prove that the hands may act as very efficient vehicles for microbes on their way from one person or place to an other. He and in this country Lord LISTER demonstrated convincingly that disinfection procedures may block this way of transmission and, by this, can cause a remarkable decrease of infection rates in the hospital environment. From this time on, the disinfection of the hands has become a routine procedure not only in the medical field but also in other branches. however, except for the finding that non-contamination is even better than disinfection, only details — though very important ones — have been added to our knowledge since then. One of the most important details was the finding that the skin harbours two different kinds of microbial flora. The one being physiologically associated with the normal skin is, with regard to its composition and quantity, very difficult to influence by ablution or even by disinfection procedures. It is called the resident flora and consists mainly of grampositive organisms as Staph.
