EFFECTIVE SOURCES OF NOSOCOMIAL INFECTION: STAFF HANDS AND HOSPITAL SURFACES

Nosocomial infections (NIs), also called hospital-acquired infections are infections acquired during hospital care which are not present or incubating at admission. Nosocomial infections remain a major global concern in all countries. Microorganisms are present in great numbers in hospital environment. Both infected persons and persons at increased risk of infection congregate in the hospitals. The subject of this study was to survey effective sources of nosocomial infections in hospitalized patients. Papers related to the importance of staff hands and hospital surfaces in transmission of bacteria in hospital were extracted from pubmed, elsevier science and yahoo from 1995 to 2011. For this study key words which were search included hospital surfaces, staff hand, transmission bacteria and nosocomial infection. Staff hands and hospital surfaces have important role in spread and transmission of bacteria in hospital. There is a consensus that the control Bacterial population in these sources, lead to the control of spread and transfer bacteria and so nosocomial infections in hospital. Hospital surfaces can serve as reservoirs of pathogenic bacteria such Staphylococcus aureus, Salmonella, Clostridium perfringens, Campylobacter, Listeria monocytogenes, Vibrio parahaemolyticus, Bacillus cereus and Escherichia coli and have important role in infection chain. Bacteria on hospital surfaces have low potential to spread. Staff hands have very contact with hospital surfaces and are more sources to transmission Bacteria in hospital. Increased Sanitation Staff hands and hospital surfaces has been considered to be the most important tool in control of transmission bacteria in hospital.
