They’re not vectors- they’re carriers. A vector is simply a diagrammatic representation of force with a given direction.
Why- they eat blood- the parasite lives in blood so it is easily transmissible by a creature eating blood from host to victim.
I think it’s their blood-sucking habit that sets them apart. Not many insects or animals for that matter thrive on human blood. Only female Anopheles mosquitoes do, not males.
The plasmodium (a protozoan parasite) which causes malaria is found not only in human blood but in bird, reptile, chimpanzee, rodent blood too. It travels from person to person (or animal to person) via mosquitoes that bite them. These being quite tiny, and their presence going virtually undetected tend to spread the disease pretty quickly. Thus an epidemic erupts.
The other answerer probably didn’t study biology, but vectors are those which not only carry the pathogen but also offer their bodies to them for breeding. Female anopheles mosquitoes feed in the night and deposit the pathogens in human body through their saliva. But blood transfusion may also spread malaria, though this is rare.
