Nosocomial is a medical term used to describe infections that originate in a healthcare setting. While it is a commonly used term, there are other synonyms that can convey the same meaning. Hospital-acquired infection is a parallel term that is often used interchangeably with nosocomial infections. Other similar words used to refer to these types of infections include healthcare-associated infections, HAI, and medical facility-acquired infections, MFAI. It's important to understand that these are serious health threats that can occur in any healthcare environment such as hospitals, dialysis clinics, surgery centers, and nursing homes. Employing good hygiene practices, handwashing, and sterilization techniques can help prevent the spread of nosocomial or HAI infections.
