When one works in a hospital in the area of care and practice, it is necessary to have certain clear criteria, which lead to a professional being what he is. Because beyond the technique must also go care that are related to the implementation of knowledge. This does not exclude emergency care or prehospital care, where it is often more important to provide prompt care over “minor” care such as hand washing or aseptic technique.
Biosecurity : is the set of preventive measures, aimed at maintaining control of occupational risk factors from biological, physical or chemical agents, to prevent a negative impact, ensuring that the end product of the procedures performed in the patient do not violate the health and safety of patients, health personnel, visitors and the environment.
Source and reservoir : The reservoir is the place where the microorganism maintains its presence, metabolizes and multiplies; having been identified as such to humans and the environment.
The source refers to the place from which the infectious agent passes to the host, this can happen by direct contact, indirect contact, air or by a vector. The source can be animate or inanimate as well as fixed or mobile. Precisely, the human being is the most important source of microorganisms. At the hospital level, the source may be the patients themselves, health personnel and, occasionally, visitors. An aspect to consider is the situations that patients can present during the period of illness: people with acute illness, people in the incubation period, those with chronic carriers, or people colonized by an infectious agent but without apparent disease. Other sources of infectious microorganisms may be the endogenous flora of the patients themselves,
In regard to the inanimate flora has been identified the own environment and hospital material that usually contaminates, and be cause of infection. Among the materials and equipment involved are disinfectants, drugs, devices and equipment.
