In the world of fiction, illnesses always progress as quickly as a heart attack. A person feeling ill will drop down within minutes of the first signs of an illness. Similarly, only hours or minutes remain for an antidote to take effect. To be fair, many diseases have a very fast progression (septicemic plague, for example, was described in Medieval writing as "the man coughs
at dawn, takes to his bed at noon, and is dead by sundown.") but this trope is about diseases that move unusually
fast (i.e. at the speed of plot).
This unrealistically speedy disease progression, apart from the need to squash a 24-hour or week-long disease into the 1 or 2 hours you can keep viewers interested, is motivated by the Rule of Drama
: Nobody cares about an illness that takes weeks to develop.

Anime and Manga
- In Yuu Watase's manga Imadoki!, early in their acquaintance, Kugyou finds Tanpopo planting flowers in the rain, and she suddenly collapses with a fever. She hates hospitals, so he takes her back to her apartment instead, and has to take care of her—including changing her clothes while she's unconscious.
- This happens a few times in Hana Yori Dango but the most ridiculous example is when Tsukushi falls into a swimming pool in a warm, tropical setting and instantly gets a bad fever. This prevents her from getting physical with Domyoji when they are finally alone together.
- In the fourth episode of Seitokai Yakuindomo, Tsuda seemed perfectly healthy until the moment he steps out from under an umbrella. Within seconds he sneezes and is sick for the next episode.
- In Fruits Basket, Yuki tends to collapse pretty quickly if he's in the cold or overexerts himself. It's explained that he was pretty sickly as a child, and his massive self esteem issues brought on by being abandoned by his family and tormented by the head of the house no doubt contributed.
- Shiina of Koufuku Graffiti would have this when she has water splashed on.
- In Ergo Proxy, when Re-l goes to the commune outside of Romdeau to retrieve Vincent, she immediately gets sick from contamination exposure when she takes off her protective suit.
- The Toxic Plate is capable of creating such in Legendary Genesis.
- In Woof Woof Power, Big D suddenly has an open bleeding chest wound a few months after he was stabbed there. You would think it would have healed, but it just suddenly springs up and he dies.
- In Chaplin's The Kid, John, Charlie's Doorstop Baby, is feeling feisty enough to beat up a kid twice his size. Not more than ten minutes later, John is severely ill, so sick that he has to be carried back to Charlie's little apartment.
- In North Sea Texas, Marcella offhandedly mentions that she needs to get her kidneys checked. The next time we see her is on her deathbead.
- The Chalet School books are pretty bad for this, probably because of Values Dissonance and girls being considered to be delicate, as well as the school's large Ill Girl contingent. Any exposure to chills, rain, drafts, mud or cold water is fairly certain to leave the victim in the grip of a life-threatening disease if they're not immediately put into a hot bath and then into bed with two hot water bottles. In one book, Jo spends three days unconscious and is bedridden for over a week after standing for literally a few minutes by an open door on a snowy day.
- Galaxy of Fear once has Tash given an injection that, within hours, has her sweating, feeling unusually irritable, and growing a rash-covered lump on that arm. Then it starts oozing, because it's the Blob Monster Virus. The one responsible actually coolly observes that the disease isn't progressing in her as fast as he'd expected.
- Happens every week on House, although the show handwaves it by saying that the patient only sought Dr. House's help when the diseases is at its final stages (when it can progress that fast), or because the overly invasive diagnostic tests and treatments House prescribed is causing an adverse reaction.
- Our Miss Brooks: In "Measles", Miss Brooks catches the measles within twelve hours of being exposed to them.
- In All Aboard, the game 4 of Westward, citizens can suddenly become sick, rendering them unable to work. They either heal after so many minutes or can be taken to the doctor's office for a quick heal.
- Game 5 Kingdoms adapts this from a simple illness into being turned into a frog by means of a curse, for the same effect.
