A mechanical vector is simply along for the ride, meaning it does not depend on the host for survival or reproduction. It can passively transport a pathogen from one host to another without being infected or affected by the pathogen itself. Mechanical vectors can include objects such as contaminated equipment, insects, or animals that unintentionally transfer pathogens from one place to another.
