The epidemiologic triangle is made up of three parts: agent, host and environment. Some of the agents that trigger non-atopic asthma are Chronic Mycoplasma pneumonia and Chlamydia pneumonia (Hong, 2012). 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.

WebWhen considering the Epidemiological Triad, there are three main factors that are taken into account: The Agent, The Host, and The Environment. Generally, the agent must be present for disease to occur; however, presence of that agent alone is not always sufficient to cause disease. A single component cause is rarely a sufficient cause by itself. As epidemiology has evolved to cover more public health issues beyond diseases, agents can also be represented as physical or chemical factors.2, Its important to note that the epidemiologic triad is a useful tool for many diseases and health events but the model only works for those issues that have one single necessary cause. online Master of Science in Clinical Epidemiology, cdc.gov/careerpaths/k12teacherroadmap/epidemiology.html, cdc.gov/csels/dsepd/ss1978/lesson1/section8.html, cdc.gov/healthyschools/bam/teachers/documents/epi_1_triangle.pdf, medicalnewstoday.com/articles/157973#types, britannica.com/science/occupational-disease/, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7302069/.
