Question

What is the difference between mechanical, biological & chemical vectors

Answer 1

Distinguish between biological andmechanical vectors.  A vector is any living organism that can carry a disease-causing microbe, but most commonly they are arthropods such as mosquitoes, flies, fleas, ticks and lice. A vector can carry the pathogen eternally or internally. ... This is called abiological vector .

Answer 2

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. Mechanical vectors, such as flies can pick up infectious agents on the outside of their bodies and transmit them through physical contact.
