The Triangle has three corners (called vertices): Agent, or microbe that causes the disease (the “what” of the Triangle) It is not transmitted from person to person, though. This demanded a broader concept of disease causation that synthesized the basic factors of agent, host, and environment focus on different classes of factors, especially with regard to infectious diseases. The ability of the pathogen to accept the new environment can also be a determining factor because some pathogens thrive only under limited ideal conditions. The triangle of epidemiology can also be called epidemiological triad.The characteristics of a disease are largely dependent on the relationship between the environment, the disease causing microorganism (pathogen) and a susceptible host.
