Question

who are vectors? What role do they play?​

Answer 1

Answer:

A vector is a living organism that transmits an infectious agent from an infected animal to a human or another animal. Vectors are frequently arthropods, such as mosquitoes, ticks, flies, fleas and lice.

Vectors can transmit infectious diseases either actively or passively:

1. Biological vectors, such as mosquitoes and ticks may carry pathogens that can multiply within their bodies and be delivered to new hosts, usually by biting.
2. Mechanical vectors, such as flies can pick up infectious agents on the outside of their bodies and transmit them through physical contact.
