Answer :
The given statement "A pathogen passes from one organism to another via the chain of infection" is true.
When an agent enters through the proper portal of entrance to infect a susceptible host after exiting from its reservoir or host through a portal of exit and being carried by a mode of transmission, the transmission has taken place. The chain of infection is another name for this progression.
Depending on the kind, pathogen can be spread in a variety of ways. They can be transmitted via skin-to-skin contact, body fluids, airborne particles, feces contact, and contacting a surface that has been contaminated. In the chain of infection, the respiratory system inhales, the mucous membranes absorb, and the gastrointestinal tract ingests.
