There are six characteristics of infectious disease agents which determine whether or not an infectious disease will be transmitted to and infect a host. These characteristics also influence the severity of the disease and even the outcome of the resulting infection. these characteristics are as follows:Infectivity: The ability of the agent to enter a host and multiply to an infectious dose, thereby producing the infection or disease.Pathogenicity: The ability of the agent to cause disease in an infected host.Virulence: This term refers to the severity of the infection. A highly virulent strain of a disease agent will most always produce severe cases or death.Toxigenicity: This term refers to the ability of the agent to produce a toxin. The resulting illness or disease is from the toxin produced by the organism/agent and not the microorganism itself.Resistance: This term refers to the ability of the agent to survive under adverse environmental conditions. It is also a measure of the agent's fragility.Antigenicity: This term refers to the ability of the agent to induce antibody production in the host. Agents that have a high antigenicity have a very low reinfection rate, whereas, agents with a low antigenicity rate have a higher reinfection rate.Based on the above list of the most significant characteristics of infectious disease agents please answer the following questions or complete the stated tasks:Identify three characteristics that you consider to be of significant importance when identifying diseases which would place those persons in a community at greater risk. (Some diseases pose a greater threat to persons likely to be exposed as a function of the characteristics presented above than other diseases.) Therefore, another perspective on this question is as follows: "If you were exposed to a disease, which of the above characteristics would be of greater concern to you as an individual."Justify your position on selecting the three characteristics of a disease agent that you believe place those exposed to it at a greater risk.Briefly discuss why the remaining three characteristics of infectious disease pathogens were not considered by you to be as significant as those you identified above.
