The current incidents of premature deaths and the increasing resistance to antibiotics illustrate how essential hygiene is and will be in the future. The hygiene expert's compact short textbook provides information in a clear and understandable form on how and where infections occur, how to protect oneself and others from infections, which means are available for the environmentally friendly reduction of microbes through cleaning, disinfection, and sterilization, and which techniques are used—from blood sampling and the insertion of an indwelling bladder catheter to dressing changes. It also covers how infections can be prevented, what hygiene requirements exist in various environments from anaesthesia and neonatology to oncology and surgery, and discusses common infectious diseases and pathogens such as CDAD, hepatitis, scabies, MRSA, noroviruses, and tuberculosis.
