A person or an animal has a blood borne disease such as malaria or yellow fever. For that disease to get to another person, it has to move to the other person's blood stream. How will it do it?
A cold infects your nose. When you sneeze, someone else breathes that air and catches your cold.
Flu infects your throat. When you cough, someone else breaches that air and catches your flu.
People do not normally breathe your blood.
There is a little animal called a female mosquito that eats your blood. Then it eats someone else's blood. Now if you have a blood borne disease it will go into the mosquito when it eats your blood.
Malaria then becomes part of the mosquitoes saliva. Its saliva acts like drilling fluid. The mosquito uses it to drill through your skin. (Oil field workers use drilling fluid to drill oil wells.) The disease gets into the new person.
The vector was the item, in this case the animal or mosquito that carried the disease from one person to the other.
A vector is an organism, often an invertebrate arthropod, that transmits a pathogen from reservoir to a host.
Mosquitos play this role by taking in a pathogen during a feeding, and then spreading it by feeding on another organism. Most noteably, mosquitos are vectors that spread malaria.
the vector carries a disease from person by person eg the mosquito is a vector carrying and spreading the malaria disease
They are caled the vectors or the method of transmission.yhe mosquito itself does not become infected but acts as a carrier and transmits the infection to humans after biting the person

Smallpox is the virus that mosquitos are not known as a possible vector.
Whenever one is bitten by a Vector mosquito. The mosquito becomes a vector after it has bitten an dengue infected carrier - usually another Human.
Infected female Anopheles mosquitos
I would say yes, as it can carries Malaria.

what is the role of a vector in the spread of a disease
The Anopheles mosquito is the vector that transmits this parasite.
The name of the vector is Anopheles mosquito. It makes the the angle of about 45 degree to the wall, when it sits there.
