What are some examples of vectors that can transmit a disease?

Answer 1

The difference is that a vector merely transports the disease and will not have any traces of the disease in its immune system. A carrier will have the infectious agent but will not show symptoms of it. Both can transmit the disease to other organisms. Ex: carrier- human with HIV but not AIDS; vector- mosquito with malaria.

Answer 2

In general a vector of a disease is the means by which it is transmitted form one organism to another.

More specifically a vector-borne disease is an infection that requires the participation of some other factor (vector) that actively infects successive victims.

For Example:

Malaria, yellow fever and West Nile Virus all require mosquitoes

Sleeping sickness requires tsetse flies.

Lyme Disease requires ticks.

The Plague requires fleas.

Answer 3

A vector-borne disease is one in which the pathogenic microorganism is transmitted from an infected individual to another individual by an arthropod or other agent, sometimes with other animals serving as intermediary hosts. The transmission depends upon the attributes and requirements of at least three different living organisms: the pathologic agent, either a virus, protozoa, bacteria, or helminth (worm); the vector, which is commonly an arthropod such as a tick or mosquito; and the human host. In addition, intermediary hosts such as domesticated and/or wild animals often serve as a reservoir for the pathogen until susceptible human populations are exposed.

Answer 4

They carry the pathogen without themselves falling ill, either in their own bodies or within parasites they host. By being very common animals around human habitats, especially in poor conditions of hygeine or pest control, they can spread the disease rapidly and easily.

However, a vector can also be a single animal that infects just one person, e.g. a bite by a wild animal carrying rabies.

The mosquito carrying the malaria organism is a classic example. Another is the rat whose parasitical flea carried the Black Death (Bubonic Plague.)

Answer 5

a vector is any agent (person, animal or microorganism) that carries and transmits an infectious pathogen into another living organism.


Examples of vectors are mosquitoes, flies, sand flies, lice, fleas, ticks and mites which transmit a huge number of diseases. Mice, rats and other rodents are also common vectors.

Answer 6

Vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans.

Answer 7

A vector is a vehicle of transmission. It could be a hand, the air, a mosquito, anything that helps move the microbes.

Answer 8

vectors are the secondary host, they serve as reservoirs from which pathogens can be continually spread to their primary hosts ensuring the transmission of the pathogens

Answer 9

A vector is an animal that transmits disease. For instance the mosquito is a vector for malaria, and ticks are vectors for rocky mountain spotted fever.
