Unfortunately, from what I have seen, it is considered to be an offense for a doctor to heal or cure anyone these days. They are only supposed to medicate to hide symptoms.
As a result of this, parasitologists have been trained to believe the lie that there are no parasites in North America.
I would look up and contact the parasitologists who are near by and ask them if they have actually tested for and found cases of Strongyloides and successfully treated them.
