What is mechanical vector transmission?

A. Physical transmission of a pathogen from a source to another object

B. Biological transmission of a pathogen from one host to another through a bite

C. Contact transmission of a pathogen by touching the vector

D. Indirect transmission of a pathogen by touching the object contaminated by the vector

Mechanical vector transmission is the physical transmission of a pathogen from a source to another object. It involves the pathogen being carried on the body parts of a vector, like flies or mosquitoes, and deposited onto a surface or host without any replication in the vector's biology.

Explanation:

Mechanical vector transmission is the physical transmission of a pathogen from a source to another object. This type of transmission occurs when a pathogen is carried on the body parts of a vector, such as flies or mosquitoes, and is deposited onto a surface or another host. Unlike biological transmission, which involves the pathogen replicating within the vector before being transmitted, mechanical vector transmission does not require any replication or involvement of the vector's biology.
