Nosocomial infections, also called health-care-associated or hospital-acquired infections, are a subset of infectious diseases acquired in a health-care facility. Historically, Staphylococci, Pseudomonas, and Escherichia coli have been the common known as nosocomial infection bacteria. Moreover, nosocomial pneumonia, surgical wound infections, and vascular access-related bacteremia have caused the most illness and death in hospitalized patients; and intensive care units have been the epicenters of antibiotic resistance . Acquired antimicrobial resistance is the major problem, and vancomycin-resistant Staphylococcus aureus is the pathogen of greatest concern. The shift to outpatient care is leaving the most vulnerable patients in hospitals. Aging of our population and increasingly aggressive medical and surgical interventions, including implanted foreign bodies, organ transplantations, and xenotransplantation, create a cohort of particularly susceptible persons. Moreover, renovation of aging hospitals increases risk of airborne fungal and other infections . To prevent and control these emerging nosocomial infections, we need to increase national surveillance, "risk adjust" infection rates so that inter hospital comparisons are valid, develop more noninvasive infection-resistant devices, and work with health-care workers on better implementation of existing control measures such as hand washing . In this review we aimed to review the previous projects which study incidence of hospital infection among delivery women with caesarean section in hospitals. Also, to discuss about the nosocomial infections and its types. We will also review the most common way a nosocomial infection is acquired, and the most common cause of nosocomial infection. In order to the modes of transmission of infection. In addition to a way to prevent nosocomial infections in hospitals. KEYWORDS: nosocomial infections, caesarean section
