What are Vectors And CArriers?What's the difference between both of them?

Vector merely transports the disease and will not have any traces of the disease in its immune system.  Example vector- mosquito. They take the disease (malaria) from an infected individual to an uninfected individual. They carry the infected agent such as blood. A disease vector itself is a carrier.

A carrier will have the infectious agent but will not show symptoms of it. Example - carrier- human with HIV but not AIDS. Carriers are the disease reservoir in which a disease lives and can multiply. They do not have the disease themselves.

a disease vector itself is a carrier. you must want to know the difference between a disease vector and a disease reservoir.

a vector is a carrier (mosquito, tick) that takes the disease from an infected individual to an uninfected individual. They do not have the disease themselves, they carry the infected agent such as blood. A reservoir is any thing (person, animal, arthropod, plant, soil or substance) in which a disease lives and can multiply. The disease NEEDS the reservoir in order to survive. A vector must be living but a reservoir can be a non living thing such as soil or water. Neither actually HAVE the disease but are simply transmitters.

PEACE!
