Re:jc virus???

thanks for the reply,
this jc virus, would it by chance reside in the CNS much the same as the herpes virus or shingella virus, this sounds very interesting in deed, i have of late been on the trail of a foreighn matter, viral/chem as the cause as a pose to immune system malfunction but not one to write off theories im open to realistic suggestion and this does appear realistic.

many thanks
