What is a nosocomial infection?

A nosocomial infection is defined as an infection acquired in a hospital or healthcare setting. These infections can occur in a variety of ways, often due to a patient's weakened immune system, invasive procedures, or prolonged hospital stays. They can be caused by a wide range of pathogens, including bacteria, viruses, fungi, and parasites that are often resistant to multiple antibiotics due to the selective pressure of the healthcare environment.

Understanding the concept of nosocomial infections is crucial because they are associated with increased morbidity, longer hospital stays, and higher healthcare costs. Measures such as stringent hygiene protocols, use of personal protective equipment, and careful sterilization processes are essential in preventing these types of infections in healthcare settings.
