It's not my idea.... it's the accumulated medical Science knowledge of thousands of doctors and scientists.... i.e. established and well known medical fact. Apparently you're the one who knows little about biochem, molecular biology and it looks like elementary research at all. a simple search on CDC, NIH, Medline, numerous medical and scientific journal websites, etc, will turn up literally hundreds of peer-reviewed papers on the downregulation effects on the immune system by helminth infections. But still even with all that formal knowledge established, doctors in western medicine still stubbornly cling to the idiotic notion that any patient with parasites is "DoP" since parasites are "Unpossible in America". .Just like flat-earthers, antivaxers, antimaskers, coronavirus-is-a-hoax believers, Dallas Cowboys fans and trumpians.... idiocy abounds. Coolaid drinkers.
