It is just the same for other illnesses. I had breast cancer. After having the tumour removed in its entirety, and 12 months of being poisoned to ensure no bits were left behind, I am officially in remission or "cured". There is a small possibility it may return somewhere in my body in the form of secondaries at some point in the future. My travel insurance premiums are now heavily loaded. Travel insurance loading for a disease that isn't there? That if it does come back it won't require emergency treatment and can wait till I get home? So unfair, but as with diabetes, it is one size fits all, no account taken of individual circumstances.
