What is a nosocomial infection?

A nosocomial infection refers specifically to an infection that is acquired in a healthcare setting, such as a hospital or long-term care facility. These infections occur because patients in these environments often have compromised immune systems, are exposed to a variety of pathogens, and may undergo medical procedures that increase the risk of infections. The term underscores the importance of infection control practices in healthcare to reduce the incidence of such infections. It highlights the need for vigilance in cleanliness and hygiene in clinical settings to protect patients. Thus, when discussing nosocomial infections, it is crucial to understand that they are linked to specific environments where healthcare is provided, rather than being defined by the type of pathogen involved or the hygiene standards in general.
