When taken in context, the quotation in Isaiah argues for illness and disease to be understood as metaphors for transgressions and iniquities--sins. The passage does not mention physical ailments, but rather is focused on the spiritual problems we cannot solve. Compare 2 Kings 5 with Naaman the leper.
Isaiah 53:4-6
Surely he has borne our griefs
and carried our sorrows;
yet we esteemed him stricken,
smitten by God, and afflicted.
But he was pierced for our transgressions;
he was crushed for our iniquities;
upon him was the chastisement that brought us peace,
and with his wounds we are healed.
All we like sheep have gone astray;
we have turned--every one--to his own way;
and the LORD has laid on him
the iniquity of us all.
