Nosocomial infections continue to increase all over the world and remain a major cause of morbidity and mortality in hospitals. There are three elements required for the transmission of nosocomial infections: a reservoir of microbial agent, a susceptible host with a portal of entry receptive to the agent and a mode of transmission for the microbial agent. Microorganisms that cause nosocomial infections derive primarily from human sources1-3 , but inanimate environmental sources are implicated in transmission4. Human reservoirs include patients, healthcare personnel, household members and visitors5. People in hospitals are usually already in a ‘poor state of health’, impairing their defense against bacteria. Invasive devices impair natural lines of defense against pathogens and provide an easy route for infection.
