TheHero may be sick, but that doesn't mean the action is going to stop. Either they are just that dedicated to their job, or fate is being extra cruel by throwing them a situation only they can handle, healthy or not. Other characters may try to keep this person in bed, but it's all in vain.

Naturally, this tends to put the hero at a handicap. If the mission involves stealth, he may find himself in need of an AntiSneezeFinger. MalfunctionMalady could be invoked if the hero has powers or magic.

Compare ICanStillFight, for the Serious Injuries version. See WorfHadTheFlu, when it is invoked as an explanation for a character not living up to the standards of {{badass}}ery expected of him.

[[folder: Anime & Manga ]]

* In the ''Manga/CardcaptorSakura'' episode "Sakura's Dizzy Fever Day", Sakura has a fever but tries to perform her school and MagicalGirl duties anyway. [[spoiler:She can barely do it with Syaoran and Meiling's help, and then passes out in bed. Good thing that Nadeshiko's ghost uses her own energy to help her a little.]]
* ''Manga/TheWorldGodOnlyKnows'' has Keima getting sick due to staying out in the rain for too long. However, that doesn't stop Keima from pushing his agenda to awaken the last remaining Goddess hiding amongst the females he's interacted with; initiating a sick-home-visit event to have the female Goddess host visit Keima's house and take care of him while he's resting in bed.
* Goku from ''Anime/DragonBallZ'' tried this when he was fighting Android 19 and sick with his heart virus. It didn't end so well.
* The ''[[Manga/SailorMoon Sailor Moon R]]'' episode "Venus Minako's Nurse Mayhem" (or "No Thanks, Nurse Venus" in the original dub), in which an influenza epidemic strikes (perpetuated by the show's villains) and all the Sailor Senshi except Venus are infected with it. Sailor Moon is so weak from her illness that she is almost unable to perform her final attack.
* In episode 9 of ''[[Manga/FutsuuNoJoshikouseiGaLocodolYattemita Locodol]]'', Yukari works the day hiding a fever. When she's finally found out she's forced to rest and let Nanako handle the last event. She spends the episode's second half in bed reminiscing about the day she first met Nanako.

[[folder: Comic Books ]]

* Frequently happens to {{Spider-Man}} in the comics, most notably during the famous story in which [[spoiler: [[ILetGwenStacyDie Gwen Stacy dies]]]].
** On another occasion he fought Doctor Octopus while seriously ill. Octopus defeated him, unmasked him, and was convinced by Peter's classmates that Parker couldn't possibly be Spider-Man, especially given the feeble fight he'd put up, and he was just dressing up. Years later during ''Comicbook/CivilWar'', Peter reveals his identity, and Ock goes on a rampage at the realization that he'd not only been repeatedly defeated by a teen, but had known the truth for years.
* Not even Franchise/{{Superman}} is immune to this trope. He gets unexpectedly sick for a number of issues starting with a bad cough. The Parasite drains his powers and catches the infection too. Towards the end he develops a sickly green glow as he gets sicker but he doesn't have time to rest since Lois ends up missing. [[spoiler: Turns it he was infected with some sort of kryptonite virus.]]
* {{Invoked|Trope}} for considerable dramatic effect during the ''Franchise/{{Batman}}'' storyline ComicBook/{{Knightfall}}. Bruce Wayne is already suffering from sleep deprivation and the flu when Bane engineers a mass breakout at Arkham Asylum... and is waiting for him when he finally staggers back into the manor.
* In one installment of the comic strip ComicStrip/{{FoxTrot}}, Jason comes to school with a cold and presents Miss O'Malley with what purports to be a note from his parents asking that he be allowed to remain ''in class''. Miss O'Malley recognizes the note as a forgery and tells Jason to go home, but Jason begs to stay and at least be allowed to take the math test.
* Another "Franchise/{{Batman}}" example is from Batman Noel (a Christmas carol inspired stand alone comic) where Bruce is suffering from pneumonia throughout the entire comic but still insists on staying out in the snow fighting crime.

[[folder: Fanfic ]]

* In the ''StarTrek'' fanfic ''FanFic/StepByStep'', Kirk attempts to stay on the bridge as per orders, even though he is sick as a dog.
* Paul does his Canalave Gym battle while suffering from a severe cold/flu in ''Fanfic/TravelsOfTheTrifecta''. He manages to win but faints right afterward.

[[folder: Literature ]]

* In ''Literature/HowlsMovingCastle'' Howl has to cast a difficult spell, go to a funeral in disguise, and fight the evil Witch of the Waste, all while he has a bad cold.
* Stella tries doing this in one of the ''Series/{{CSI NY}}'' tie in novels, only to eventually pass out and require hospitalization.
* Despite having a bad cold in ''Literature/TheWomanWhoMadeMachinesGoHaywire'', ''and'' an out-of-control jinx, Iris is forced to head to work or face losing her job.

[[folder: Live Action TV ]]

* ''Series/MightyMorphinPowerRangers:'' Kimberly is sick with a cold during season 3's tripart opener, "A Friend In Need". She has to stay behind resting while the other rangers travel to Edenoi. However, Zedd and Rita send down a monster, forcing Kimberly to fight in spite of her illness. It's a tough fight, but the monster catches her cold and has to return to the moon so that Finster can cure it.
* The ''ParksAndRecreation'' episode "Flu Season". Leslie [[ICanStillFight keeps working and insisting that she is not sick]], despite being obviously ill to the point of having fever hallucinations.
* Series/BuffyTheVampireSlayer once ended up in a hospital bed with a nasty fever. But it soon became evident ''something'' needed to be slain, and she was still feverish when she confronted it.
* In one episode of ''HeadOfTheClass'', Arvid has the flu, but refuses to stay home because it will disrupt the perfect attendance record he has maintained since kindergarten. As a result, ''the entire high school'' catches it, to the point where he is apparently the only person in the building by the end of the episode.
* Piper does it twice on ''Series/{{Charmed}}''. In season 1 episode "The Wendigo", Piper is exhausted, feverish, and having dizzy spells at work, but stays in because, well, Piper's like that. In season 2 "Awakened", she's having coughing fits and "feels funky," but she stays at work until she collapses. Both situations are gross because Piper serves food.
* The ''{{Series/MASH}}'' episode "Carry On, Hawkeye" has everyone at the 4077th come down with the flu save Hawkeye, who's seemingly immune and thus left to run the O.R. practically by himself. Then ''he'' gets sick, but is forced to keep going.
* ''Series/WheelOfFortune'': Pat Sajak hosted two weeks of episodes from San Francisco in November 1996 despite coming down with laryngitis at the time. By the end of the week, his voice was nearly gone, so he and hostess Vanna White traded places in the BonusRound.
* In ''Series/BrooklynNineNine'', the incredibly tough Detective Rosa Diaz plans to do this when she comes down with a cold while trying to make a breakthrough in a major case. It's subverted, however, since she ends up going hyper after taking too much cold medicine, then crashing and sleeping for ten hours straight, so doesn't manage to get a single useful thing done whatsoever. The other characters help out and get her the information she needs in the meantime.

[[folder: Radio ]]

* Radio/PaulHarvey hosted several episodes of ''Paul Harvey's News and Comment'' and ''The Rest of the Story'' in the early 2000s despite a bout of pneumonia that left him sounding very rough. (He also zig-zagged this by letting others fill in for him.)

[[/folder]]

[[folder: Western Animation ]]

* On ''WesternAnimation/TheSimpsons'', a Japanese worker goes to work despite having the flu, and coughs inside a box that's bound for Springfield.
* ''WesternAnimation/BatmanTheAnimatedSeries'': Batman comes down with a cold after being exposed to Mr. Freeze's ice ray. Still he has to go out and stop the villain (after all he's the God Damn Batman!) Alfred makes him take a thermos of chicken soup with him -- which ultimately saves the day as Batman defeats Freeze by using the thermos to smash his containment suit's helmet.
* Averted in ''WesternAnimation/SpongebobSquarepants''. When Spongebob is sick, he ''attempts'' to drag himself to work anyway, but Mr. Krabs notices how sick he is and sends him home to get some rest.
* ''KimPossible'' had an episode where both heroes and villains work through the cold. Kim, Drakken, Ron, Shego and Duff Killigan all end up with colds as they take turns stealing an experimental ray back and forth from each other -- none of them knowing what it does. Ultimately the ray gun gets destroyed and [[ShaggyDogStory ironically it turns out it was designed to cure the common cold]].
* WesternAnimation/{{Ben 10}} caught a cold in one episode, and his symptoms carried over into his alien morphs, clogging Wildmutt's heat sensors, giving Four-Arms a smelly rash, and changing Heatblast's powers from fire to ice. He took advantage of the latter, cooling down a nuclear reactor that was being attacked by villains.
* In ''WesternAnimation/TimeSquad'', with Otto sick with a cold, Buck and Larry are forced to solve a mission without him; this doesn't work out because the two are clueless about American history and the signing of the Declaration of Independence and have to repeatedly go back to the satellite and ask Otto what to do next because they are so dependent on his knowledge. In the end they give up and drag a very sick Otto out to 1776 to have him recite the opening to the Declaration, where he then passes out from exhaustion.
* Franchise/SpiderMan loves this Trope, as it's been seen in several animated incarnations going back to "Horn of the Rhino" in [[WesternAnimation/SpiderMan1967 1967]]. Here we see both SneezeOfDoom and a BatmanGambit--a can of pepper borrowed from Aunt May's kitchen--to get Rhino also sneezing, just long enough to throw his attacks off.
