Lingering Pathogens (1970)


Course Description

Lingering pathogens are a common and often unrecognized cause of persistent, baffling and often debilitating health problems. This course is designed to provide an analytical framework to assess and manage disorders associated with “lingering pathogens” as defined by Chinese medicine. These disorders are characterized by persistent illness or morbidity subsequent to an acute infectious process that was unresolved, poorly managed or occurred in an individual without the resources to throw it off. Lingering pathogens are quite common in clinical practice, and their manifestations range from the mild – persistent cough, sleeplessness, fevers and so on, in the aftermath of a cold or flu – to the severe in which a pathogen may last for months or years and contribute to health conditions that may be diagnosed as autoimmune. We will start with a look at the history and analytical models and their development over the centuries (including the Shang Han Lun, Wen Bing, concepts of gu syndrome and so on) and the techniques developed for treatment, then progress to a close look at etiology and common clinical patterns and their management. Case histories will be used to illustrate treatment strategy.
