Biological transmission differs from mechanical transmission in that biological transmission involves reproduction of a pathogen
Taya2010 [7]

Biological transmission involves reproduction of pathogens in an arthropod vector prior to transmission. In terms of epidemiology, we can term a vector as an organism that is from infected to the uninfected. An infected organism which develops biological vector passes it to its host. For example a mosquito.

 A mosquito being a mechanical vector carries an infected organism to its host either through the legs or through the other body parts
