Passenger virus
Passenger Virus
Passenger Virus (pronunciation: /ˈpasɪndʒər ˈvaɪrəs/) is a term used in the field of Virology to describe a virus that is present in an organism but does not cause disease. The term is derived from the English words "passenger", meaning someone who travels in a vehicle without participating in its operation, and "virus", from the Latin virus meaning toxin or poison.
Etymology
The term "Passenger Virus" is a combination of the English word "passenger", which has its origins in the Middle English passager meaning to pass by, and the Latin word virus which means poison or slimy liquid. The term is used to describe a virus that is present in an organism but does not cause disease, much like a passenger in a vehicle who is present but does not participate in driving the vehicle.
