They simply need to be detoxed on a regular basis if you want to stay healthy. Many diseases in this country are misdiagnosed and treated without the first thought that there may be a parasitic connection. This should be the first problem treated in all patients. There is simply not the man power to do this on a large scale. Now many parasites can not be found in the stool.
Liver flukes, blood born, etc.
So this has been a real problematic issue for the conventional medical system. The other problem the conventional medical field has is their treatments. There was no known drug available for tapeworms due to the fact that they are so well suited to our body that you literally have to kill the patient to get the worm. They did have a treatment that aggravated the tapeworm and we were on call to check the stool everyday to see if the head had come out. So, the drugs they have to kill parasites, in most cases, have to be at such a high toxic level that the risk is not worth it, especially in a patient that is already sick.
