Delusions of Parasites?

Someone sent me this article  in which the author Simon Yu, a doctor explains his views on parasites.   In the United States, doctors are trained in very specific ideas of both diagnosis and treatment, they are only as good as their training and when faced to think outside the box then this presents many problems for them.   One of these problems is parasites.   It is widely believed that Americans do not get parasites, this was told to me by an Infectious Disease doctor.   Where did he get this information?  What is the basis of his belief?

Parasite infections are prevalent in many countries mostly through poor sanitation and hygiene.   American has better practices than most but that does not mean that Americans cannot have parasites.  *Doctors believe that Americans can get them only if they traveled outside of the US.

Doctors are simply not trained in seeing the signs of a parasitic infection and testing methods are highly unreliable.   At this point the only lab that seems to have some handle on detection is Metametrix in which they use the new technology PCR to detect parasites.

Anyhow the article is good and worth reading.
