Since you keep repeating this ridiculous statement:

Please provide your source that indicates there has only been one case of toxoplasmosis in humans in Hawaii.  Given that 60 million Americans nationwide are infected (per the CDC), only one case in Hawaii seems highly unlikely.

G.D. Wallace, in his paper  published in the Hawaii Medical Journal entitled "Toxoplasmosis in Hawaii"estimated that approximately 60% of adults in Hawaii were infected with toxoplamosis.

Your repeated assertion is almost certainly wrong.
