Illnesses — Tag Meaning
A canonical tag for sickness of the ordinary and serious kinds alike, from flu-season misery to undiagnosed dread. It overlaps with sickfic but reads more as disclosure than as genre promise.
What to Expect From "Illnesses" Fics
A character is unwell, with symptoms on the page; severity is set by companion tags. Caretaking scenes are the usual reward.

A whole subgenre built on one premise: a character gets sick and someone takes care of them.

Hospitals
The non-AU hospital tag: canon characters in waiting rooms, recovery wards, and bedside chairs after the plot's violence catches up with someone.
