While this trope is usually done out of malice, there are some cases where someone gives someone a disease for benign parties. A real-life example of this is "pox parties," where parents try to build up immunity to chicken pox by deliberately exposing their children to other children with the disease. A more fantastical example would be a character who is [[IdealIllnessImmunity immune to all diseases]] being exposed to a disease in order to develop antibodies that can then be given to others.

The motives of why a person would do this can vary. Perhaps they feel bitter about their illness and want to share their misery with others. If they worship a god of disease, perhaps they might view the act of spreading their illness to others as some kind of holy mission. If the disease is deadly, perhaps the person seeks to [[TakingYouWithMe take as many people as they can with them before they die]]. A simpler possibility is that the character is a {{jerk|ass}} who just doesn't care about other people's health or [[ForTheEvulz gets a kick out]] of making other people sick.
Some variants of this trope are less about spreading the disease in general and more about hurting specific people or groups. A person who hates or wants revenge on a specific person might try to give their disease to said hated person.
While this trope is usually done out of malice, there are some cases where someone gives someone a disease for benign parties. A real life example of this are "pox parties," where parents try to build up immunity to chicken pox by deliberately exposing their children to other children with the disease.

The motives of why a person would do this can vary. Perhaps they feel bitter about their illness and want to share their misery with others. If they worship a god of disease, perhaps they might view the act of spreading their illness to others as some kind of holy mission. If the disease is deadly, perhaps the person seeks to [[TakingYouWithMe take as many people as they can with them before they die]]. A simpler possibility is that the character is a {{jerk|ass}} who just doesn't care about other people's health or [[ForTheEvulz gets a kick out]] of making other people sick.
Some variants of this trope are less about spreading the disease in general and more about hurting specific people or groups. A person who hates or wants revenge on a specific person might try to give their disease to said hated person.
While this trope is usually done out of malice, there are some cases where someone gives someone a disease for benign parties. A real life example of this are "pox parties," where parents try to build up immunity to chicken pox by deliberately exposing their children to other children with the disease. A more fantastical example would be a character who is [[IdealIllnessImmunity immune to all diseases]] being exposed to a disease in order to develop antibodies that can then be given to others.
{{Supertrope}} to TyphoidMary, where a character is sick but unintentionally spreads their sickness to others rather than doing it with intent (though villains can weaponize such a character to deliberately spread illness).
A {{Plaguemaster}} is sometimes this. Compare/Contrast GettingSickDeliberately, where a person makes themselves sick.
Administrivia/NoRealLifeExamplesPlease, as there a quite a number of real life controversies and recent events where this happened.
!!Examples:

[[folder:Anime & Manga]]
* ''Manga/The100GirlfriendsWhoReallyReallyReallyReallyReallyLoveYou'': Karane attempts to invoke this trope in Chapter 2 as an excuse to kiss Rentarou after a wayward sneeze leads the girls to pretend he's sick to try and get his SacredFirstKiss.

* ''Film/TheCassandraCrossing'': One of the protesters of the US military's presence in Switzerland manages to break into a research lab where dangerous biotoxic cultures are stored. Naturally, he gets bashy-smashy with this stuff, infecting himself. He later escapes onto a train bound for Nuremberg, spreading the contagion to the other passengers.
* ''Film/CoolCatFightsCoronavirus'': Zigzagged -- Dirty Dog apparently has COVID, since he tries to spread it to children by coughing on them. However, he also claims that he is using magic to spread COVID, and that [[EskimosArentReal COVID is a scam]].
* ''Film/ItFollows'' incorporates this with elements of a {{Curse}}. The {{Curse}} is a sexually transmitted disease where a person follows you relentlessly and then kills you when it gets too close. It can only be survived by being spread (and then spread again and again), giving It someone else to follow. After being unknowingly infected from a one-night stand who, it's implied, did know what she was doing, Hugh infects Jay with the [=STD=] and encourages her to pass it on. [[spoiler:Which she does, though not to anyone unaware. She gives it to Greg (who's willing, but doesn't believe in it), and then to Paul (also willing, but this time he believes in it). It's implied that Paul may pass it on to [[DisposableSexWorker a sex worker]] at the end, but it's not confirmed.]]
* ''Film/OperationDeltaForce'': This is the eventual endgame of the terrorist leader and BigBad, Johann Nash. Raiding a bio-lab in Johannesburg for samples of a powerful viral strain and it's antidote, Nash and his mooks were intercepted by the Delta Force before they can escape, with the Delta Force obtaining the virus but not the antidote. Then the virus sample's canister turns out to have sprung a leak, leading to ''everyone'' getting infected; since the terrorists have the only antidote around Nash decides to send his men to several neighboring cities to spread the virus as far as possible.
* ''Film/Smallpox2002'' is an entire film with this premise. A man walks through New York City at rush hour, having purposefully infected himself with (eradicated) smallpox stolen from a foreign power. He is discovered to have [[DrivenToSuicide committed suicide]] mere days after the outbreak started, having driven the world to the brink of collapse. His motive for doing this is [[RiddleForTheAges never confirmed]]; some people suspect that he's a foreign agent. His suicide note implies (but does not confirm) that he's a religious fanatic, as he quotes a passage from the Bible about the plague and the purification of society.

* In ''Literature/ASeriesOfUnfortunateEvents'', the Hook-Handed Man mentions having a "lovely dream" where he sneezed without covering his mouth and giving everybody germs.

[[spoiler:When Damian was at RADA, his classmate, Dan Roberts, got the role of Hamlet in the final-year play. Damian was angry, as he felt he deserved the part. Damian got his girlfriend, Amanda Leigh, to seduce Dan, as she had glandular fever. He contracted glandular fever and lost the role of Hamlet, having to play Laertes, while Damian took over Hamlet. Damian became extremely successful, while Dan's career stalled, and he blamed it on Damian and Amanda. He killed Amanda, but wasn't able to get at Damian due to his extraordinary Hollywood success.
