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 nursing facility, rather than in the community. These infections can occur in patients receiving treatment for other conditions and often arise from various sources, including contaminated instruments, medical devices, or the hands of healthcare providers. The presence of certain risk factors in hospital environments, such as invasive procedures, weakened immune systems, and prolonged stays, makes patients more susceptible to these infections. Therefore, understanding that nosocomial infections are linked to a healthcare environment is essential for proper infection control and prevention measures within clinical settings.
