Theoretically, HITH/HLLE strikes weakened parts of the fish (lateral line, sensory pores). When the fish is stressed, these are weakened to a further point in which they will deteriorate, whether hexamita, or whatever caused it.
Now this is just my theory.
Therefore, you must find the cause of stress- poor water quality, bad diet, etc.
And stop it.
