Infettato

Infettato is an Italian term used as the past participle of the verb infettare and is commonly employed as an adjective to indicate that a subject or specimen harbors a pathogenic agent. It describes a state of infection in a living being, such as a person, animal, or tissue, and can refer to samples in laboratory contexts. A person may be described as infettato if they have contracted an infection; a tissue or sample may be described as infettato if it contains an infectious agent. The term can indicate that the infection is active, though in practice further diagnostic information (symptoms, test results) is usually required to determine clinical status.

Etymology: infettato derives from infettare, which in turn comes from Latin infectus or related forms through the Latin verb infectare; the sense of contamination or taint is carried into Italian. The related noun infezione means infection, while infetto or infettato are used to describe the infected state.

Usage notes: infettato emphasizes the host or sample as being infected, distinct from terms such as colonizzato (colonized) when the agent is present without causing disease. In everyday language, infettato often appears in media or public health communications to describe individuals or communities affected by a pathogen. See also infezione, contagio, malattie infettive.
