| 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 |
