The chain of infection describes the situations that lead to acquiring a pathogen. The links are: infectious agent, reservoir, portal of exit from the reservoir, mode of transmission, and portal of entry into a susceptible host.
infectious agent: varicella zoster virus
reservoir: humans and a few other primates
portal of exit from the reservoir: droplets from coughing or sneezing, fluid from blisters and sores
mode of transmission: airborne or direct contact
portal of entry into a susceptible host: upper respiratory mucosa
There is none as cancer is not an infectious disease. Some forms of cancer, though not all, may be caused by infections agents.
The chain of infection is path that an infectious disease or virus will take. This chain of infection is used so as to tame the infection on time.

source, means of transmission, susceptible host
It is important to break the chain of infection so that it doesn't spread. Infections have the ability to kill individuals.
A polypeptide chain is a chain of amino acids, which make up proteins
A chain.
plot
The chain of infection for biological agents begins with the etiological agent and includes the reservoir, the portal of exit, and the mode of transmission. The portal of entry and the susceptible host end the chain.
True
