(B). What is the epidemiological model triad of the causative factors for the disease in human.Explain

Expert Solution

Epidemiology is a branch of medicine which deals with the incidence, distribution and control of diseases related to human health.

Epidemiological triad well is a traingle shaped sign which is a traditional model for infectious diseases.

The triad consists of an external agent, a susceptible host and the environment which brings the agent and host together.

Let us see what are these three components in detail.

The diagram shown below is the epidemiological triad,

Agent : an agent is an external source or any organism which is susceptible to create infection in the human being.

For example, salmonella bacteria causes typhoid.

Here, salmonella bacteria is the agent.

Host : A susceptible host is the human being or the person who comes in contact with the agent and who affects with the disease or will be the carrier of the disease ( one who is able to spread the disease to others but will not have any symptom of that particular disease in that person who carries the agent).

For example : In this present scenario of spreading of corona virus, the man is the host which carries the virus within the body and virus is the agent which is causing infection. When a man with corona virus comes is contact with another person, the virus enters the body of the another individual.

Environment : A suitable or favourable environment is necessary for the agent to enter the body of the host to create infection.
Some infectious organism needs cold environment but some others need a normal body temperature of human being for spreading the infection.
Environment can be anywhere for the agent comes in contact with the host.

Note : Epidemiological triad well explains how a person affects the disease with the three components namely an agent, a susceptible host and an environment.

Epidemiological methods are used in a variety of public health areas (including infectious disease, chronic disease, and social health) and settings (including the community, schools, and the workplace). Epidemiological methods are used to assess, describe, analyze, and make comparisons of populations to inform evidence-based practices, policies, and interventions. Propose a study based on the methods you have learned thus far designed to investigate an association within one of the public health areas listed (infectious disease, chronic disease, or social health)...
