Knowing that a condition is asymptomatic is important because:
If the disease is not treated, however, it may progress to the stage where it causes subjective symptoms and abnormal physical findings. Therefore, the distinction be-tween asymptomatic and symptomatic disease is one of degree, depending primarily on the extent of the disease. The term etiology means cause. A disease of unknown etiology is one for which the cause is not yet known. Unfortunately, many diseases fall into this category. If the cause of a disease is known, the agent responsible is called the etiologic agent. The term pathogenesis refers to the manner by which a disease develops, and a pathogen is any microorganism, such as a bacterium or virus, that can cause disease.
