Active carrier
Active carrier
An active carrier (pronounced: /ˈæktɪv ˈkærɪər/) is a term used in medicine and microbiology to describe an individual or organism that has contracted an infectious disease, but who displays symptoms and can transmit the disease to others.
Etymology
The term "active carrier" is derived from the English words "active", meaning engaged in action, and "carrier", referring to a person or thing that carries, holds, or conveys something. In the context of medicine and microbiology, a carrier is an organism that harbors a specific infectious agent without discernible symptoms and serves as a potential source of infection.
