Unless the new agers are right about moving into a high vibrational frequency zone that worms cannot infect, then once a host always a host and if you got them once, there is nothing to stop them from coming back and reinfecting you again and again, except systemic cleansing on a routine and regular basis. We deworm our cats, we deworm our dogs, ranchers deworm the livestock. But doctors are not teaching people the importance of regular deworming of humans too, to prevent disease.
