Animals that participate in the life cycles of pathogens and transmit pathogens from host to host are referred to as Vectors.
What are Vectors?
Vectors are animals that are responsible for transmitting or transporting pathogens from one individual to another. Vectors are not responsible for the cause of the disease, their only function is to spread the disease.
For example Mosquito helps in the spread of malaria parasites(plasmodium), they spread this disease from one human to another. Flea is also another vector that transmits/spreads plague.
Another example of a vector is the tsetse fly, this vector is responsible for spreading trypanosomes from animals to human. The tsetse fly is not responsible for causing the disease, their role is just to spread the disease.
