You are correct that U.S. doctors aren't educated enough in this field. I learned about this problem from South American Doctors who handled my ex and his employees when they worked in the Amazon. They ALL got parasites. They then related how U.S. doctors won't do any good if you go back to the states with the parasite problem because of lack of education and not very good labs. They said you will stay sick cause the labs here don't test for the thousands of parasites that are out there, they only test for a couple or a few at best. It's sad that the CDC numbers are so skewed making our nation look as if it is parasite free when the truth is that we just have horrible doctors and labs in this field that can't detect the most basic parasitic problems.
