On the Wikipedia page on Hideyo Noguchi, one can find the following:

Possibly his erratic and irresponsible behaviour was caused by the untreated syphilis with which he was diagnosed in 1913, and which may have progressed to neurosyphilis. In any case, he was careless not only of his own safety, but also of the safety of those around him, and despite repeated promises to Young, failed to keep infected mosquitoes in the specially designed secure housing.

Is there any study confirming or refuting that Hideyo Noguchi had neurosyphilis?

In 1928, at may 11 he was diagnosed yellow fever. He felt strange because he had immunity of yellow fever. However after he died, and his blood was injected to a monkey. The monkey was diagnosed yellow fever. Then also Dr.young died with yellow fever after about one week.

  • $\begingroup$ Can you expand more on how this answers the question? I don't quite see how it confirms that Noguchi had neurosyphilis. $\endgroup$
