Biological Transmission Differs from Mechanical Transmission in That Biological Transmission

Question

Biological transmission differs from mechanical transmission in that biological transmission
A)occurs when a pathogen is carried on the feet of an insect.
B)involves fomites.
C)involves reproduction of a pathogen in an arthropod vector prior to transmission.
D)requires direct contact.
E)works only with noncommunicable diseases.

Accepted Answer

Biological transmission requires the pathogen to undergo reproduction or development within an arthropod vector before transmission can occur. This is different from mechanical transmission, which involves passive transport of the pathogen (such as on the feet of an insect) without any reproduction or growth of the pathogen within the vector.
