Occurs when a genetically susceptible individual is exposed to a biotoxin and as a result becomes chronically ill over a period that usually spans years. The most notable exposures are to a host of biotoxins and inflammagens found in a water damaged building or home. This is more common than you might think. According to the World Health Organization, 50% all buildings/homes are water damaged in the United States. Another common cause is the toxins associated with Lyme disease. There are other causes of CIRS, but for now these are the two most commonly recognized, i.e. living or working in a water damaged building or post Lyme disease.
