Nosocomial infections refers to infections acquired during hospitalization, with symptoms usually occurring within forty-eight hours after admission.
The origin of nosocomial infections can be attributed to the following:
- Bacterial flora already present in the patient;
- Microorganisms from the environment through transmission from: carriers colonized at admission, admitted to wards without undergoing surveillance, isolation or eradication of the germ(s); patients who have developed the infection but who have not been isolated;contact with contaminated objects and surfaces; medical personnel, usually via their hands; invasive procedures such as the installation or maintenance of a device(1).
The current probability of infection in

The increase in infection-related health activity is the result of a gradual increase in specific risk factors such as antibiotic pressure and the greater complexity of patients’ conditions. Despite their strong impact, both socially and economically, the surveillance systems and programs currently deployed for the prevention of nosocomial infections are quite dishomogeneous and, in many situations, do not exist at all.
There are two main discriminating factors in this critical situation. The first relates to the chronic lack of funds for a serious policy of prevention, particularly in terms of an effective screening process. The second concerns the lack of accurate knowledge and widespread awareness on the part of health-care operators who are apparently unable to see the problem, in its complexity, as a factor that impacts on all health-care processes, be that at regional or hospital level.
Another crucial element to consider is the emergence of bacterial strains resistant to antibiotics,given the widespread use of these drugs as a prophylactic or a therapeutic regimen.
