Differentiate between carriers and vectors by giving suitable examples in a tabular form .

Vector Carrier
A vector is an organism who passes on a disease without getting sick.A carrier is an organism who has no symptoms of a disease but harbors the pathogen in its body and passes it on to someone else.

The vectors may act as intermediate host for the completion of part of life cycle of pathogen.


Carrier may or may not be needed by the pathogen to complete its life cycle.


The vector harbors pathogen mostly for short time.The carrier state may be of short or long duration (temporary or transient carrier, or chronic carrier).
For example; mosquito with malarial parasite.For Example: human with HIV virus but not AIDS; or human with pathogen Salmonella typhi but not Typhoid.
