Relating to or denoting infections acquired in a hospital or healthcare facility. These infections occur during the course of receiving treatment for other conditions and were not present or incubating at the time of admission.
From Greek 'nosokomeion' meaning hospital, which combines 'nosos' (disease) and 'komein' (to take care of). The term literally means 'place where diseases are tended to,' highlighting the ironic reality that hospitals, while healing, can also be sources of infection.
The word nosocomial reveals a dark irony - it comes from the Greek word for a place that cares for the sick, yet it describes infections you catch while being cared for! It's a reminder that even our places of healing can harbor dangerous microbes that have adapted to survive in medical environments.
