leprosy
癩 centers on leprosy, a chronic infectious disease that causes skin lesions and nerve damage.
癩 combines the sickness radical 疒 with 賴, which likely provides the sound ライ. The character was created to specifically denote leprosy.
The sickness enclosure 疒 wraps around 賴, a component that suggests reliance. Picture a person with leprosy relying on others for care as the disease takes hold.
For ライ, imagine a person with leprosy lying in bed, and the sound of their labored breathing is a raspy 'rai' — ライ.
