[Legal aspects of the supervision of nosocomial infection].

Hospital infections are a serious epidemiological problem since hospital departments have been established. Through many years the problem of hospital infections was unsatisfactorily recognized and not until 1970 appeared in Poland publications concerning hospital infections and suggesting systems of control as well as inspection. In the same time acts and instructions were issued defining principles and procedures in case of nosocomial infections. The aim of this paper was to show changes in legislation concerning the incidence, registration and action against hospital infections.
