I have been getting these 'flukes' on a daily basis for the last 3 or so months. The doctors, (holistic, MD, infectious disease specialist, public health) all state that unless they can identify parasites in the O&P stage, that the they are not there. (They don't want to see pictures.) Hmmm! Since they cannot be identified easily, and they have not been seen as a problem in the U.S., could it be that we don't have them? It's a viscous cycle! The doctor from the health department and the infectious disease department said they had never heard of these 'flukes'.
