uninfected

Uninfected is a term used to describe an organism, cell, or area that has not been invaded or affected by a pathogen or infectious agent. In biological and medical contexts, it signifies a state of health and freedom from disease-causing microorganisms such as bacteria, viruses, fungi, or parasites.

An uninfected person or animal is typically not exhibiting symptoms of an infectious disease. Similarly, an uninfected wound is one that shows no signs of bacterial or microbial contamination, which is crucial for proper healing. In laboratory settings, cell cultures are often kept in uninfected states to serve as control groups in experiments investigating the effects of infections or treatments.

The concept of being uninfected is fundamental to understanding disease transmission, prevention, and treatment. Public health measures like vaccination, hygiene practices, and quarantine aim to maintain uninfected populations and prevent the spread of pathogens. Diagnostic tests are employed to determine if an individual or sample is infected or uninfected. A state of being uninfected is generally considered desirable and indicative of good health or a sterile environment.
