Research. In all cases I have researched anti-fungal, anti-bacteria, and anti-viral drugs or non-drugs have proven to be of no help for EC. Numerous biopsies from multiple people with EC have shown no fungus, no bacteria, and no viral infection. Also the characteristics of EC are unlike an infection, effected area is localized to one specific area, never decreasing or increasing in size or severity. An infection would seem to present itself in varying degrees of severity and size with no defined border.
