Answer :
A vector is an organism that facilitates the spread of disease from one host to another. examples include mosquitoes, ticks, and fleas.
The transmission of a disease occurs when it spreads from one person to another. Each mode of transmission involves a pathogen and a host. Pathogens might be bacteria, viruses, fungi, parasites, or prion diseases (a protein particle). These are the pathogens that cause sickness.
- Mosquitoes are without a doubt the most significant arthropod carriers of illness. The persistence and spread of pathogens that cause malaria, lymphatic filariasis, and a variety of viral illnesses are entirely dependent on the availability of competent mosquito vectors.
- Ticks are significant vectors of pathogenic protozoa, bacteria, and viruses that cause serious and potentially fatal infections in humans and animals all over the world.
- Fleas are carriers of two bacteria-borne diseases that affect humans. Plague is the most serious and well-known flea-borne illness in the world.
