The triad is used to determine the cause of infectious diseases, non-infectious diseases, and accidents or injuries. endobj Centers for Disease Control and Prevention. 1.Prospective For each of the following risk factors and health outcomes, identify whether they are necessary causes, sufficient causes, or component causes. First epidemiologists have to identify the three vertices of the triangle: Agent: A type of virus called a coronavirus, identified as SARS-CoV-2. The area of study that has helped health-care providers and families answer these questions is called: The third aspect of the epidemiological triangle, environment, refers to characteristics described above, such as cultural acceptance, pockets of poverty and/or a history of violence.
