Generally, the agent must be present for disease to occur; however, presence of that agent alone is not always sufficient to cause disease. To prevent the spread of disease, at least one side of the Epidemiologic Triangle must be broken. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. To keep diseases at bay, its important to thoroughly understand the Epidemiologic Triangle and the implications of each side. Determine if it is a common source, propagated outbreak, or progressive outbreak. For example, lung cancer may result from a sufficient cause that includes smoking as a component cause.

Environmental factors include physical features like geology or climate, biologic factors like the presence of disease transmitting insects and socioeconomic factors like crowding, sanitation and access to health services. Sometimes, the host may not show any signs of illness and could be unaware that they have the disease.

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 causal epidemiological triangle of diseases is formed by the environment, the agents and the host. 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. Pellentesque

Anthrax can infect a person in three ways: by anthrax spores entering through a break in the skin, by inhaling anthrax spores, or by eating contaminate, undercooked meat. 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.
