Question

Differentiate between carrier and vector.

Answer 1

Answer 2

Vector	Carrier
A vector is an organism that passes on a disease without getting infected.	A carrier is an organism that itself does not have any symptoms of a disease, but the pathogen lives in its body and is passed on to others.
A vector may act as an intermediate host for the completion of part of the life cycle of the pathogen.	A carrier may or may not be needed by the pathogen to complete its life cycle.
Pathogen inhabits a vector usually for a short period of time.	The carrier state may carry the pathogen for a  short or long duration (temporary or transient carrier or chronic carrier).
Example- Mosquito with malarial parasite	Example- A human with HIV virus but not AIDS or a human with pathogen Salmonella typhi but not typhoid
