The Centers for Disease Control and Prevention (CDC)defines an outbreak or epidemic as the occurrence of more cases of disease, injury, or other health condition than expected in a given area or among a specific group of persons during a specific period. When investigating how a disease spreads and how to combat it, the epidemiologic triangle can be an invaluable tool. The epidemiological Triangle model includes three key elements: the agent, host, and environment. Figure 4. Inhalation: Initial symptoms are like cold or flu symptoms and can include a sore throat, mild fever, and muscle aches. A public health nurse (PHN) is asked by the hospital administration to find out why there are so many pediatric asthma patients coming to the emergency department (ED) for treatment and to develop a plan to reduce admissions by 10%.

Rothman KJ. For an epidemiologist, understanding how diseases spread is essential. The premise is that changes in one of the elements of the triangle can influence the occurrence of disease by increasing or decreasing a person's risk. Opportunities for exposure are often influenced by behaviors such as sexual practices, hygiene, and other personal choices as well as by age and sex. *Honolulu, Hawaii, and Anchorage, Alaska, were excluded.

First epidemiologists have to identify the three vertices of the triangle: Agent: A type of virus called a coronavirus, identified as SARS-CoV-2. Since different diseases require different balances and interactions between these three factors, its critical to fully assess each component in order to develop effective control and prevention measures. Epidemiology is the study of how diseases affect the health and illness of populations. A number of models of disease causation have been proposed.

Human anthrax comes in three forms, depending on the route of infection: cutaneous (skin) anthrax, inhalation anthrax, and intestinal anthrax. It is reported to be 93% effective in protecting against anthrax. Therefore, it isnt an adequate model to use for diseases such as cardiovascular disease, cancer, and other diseases that appear to have multiple contributing causes.3, The host is the organism which is exposed to and harbors a disease. He has been asked to work with the team that does outbreak investigations and conducts surveillance.

As the CDC explains, a variety of factors intrinsic to the host, sometimes called risk factors, can influence an individuals exposure, susceptibility, or response to a causative agent.2,3, Completing the triangle used by epidemiology to model the study of disease and health issues are the extrinsic factors that affect the agent and provide opportunity for the host to be exposed.
