Abstract

Background and Aim: Nosocomial infection is an infection that a patient develops 48 hours after hospitalization or up to 72 hours after discharge. The infection should not exist at the time of admission, and should not be in the latent stage. Nosocomial infections can lead to economic, social, and physiological problems for the patients and hospital staff.
