__NOTOC__
'''Lung rot''' is a long-lasting [[disease]] that can be fatal if untreated.

==Overview==
Lung rot appears after prolonged exposure to [[rot stink]], and affects both of a person's lungs. It can't be acquired from an [[event]].

The higher the [[rot stink|"rot stink" hediff]] severity, the more likely common the disease is. At 0.5 severity, there is an {{MTB}} of 8 days at 0.5 severity to get this disease. This goes up to a {{MTB}} of 0.5 days at 1.0 severity.{{Check Tag|Mechanics?|How does this scale? Linear or a curve?}}

===Prevention===
Preventing colonists from inhaling rot stink gas, which is done by avoiding rotten [[corpse]]s; a rot stink severity of at least 0.5 is required to contact lung rot. Try to avoid being in melee with [[scaria]]-infested [[animal]]s, as they will immediately rot on death. Otherwise, haul, [[grave|bury]], [[fire|burn]], or [[electric crematorium|cremate]] corpses in a timely manner, or wait for them to finish rotting.

In the [[Biotech DLC]]{{BiotechIcon}}, [[face mask]]s, [[gas mask]]s, and other sources of [[Toxic Environment Resistance]] all reduce the severity of rot stink.

[[Detoxifier lung]]s{{BiotechIcon}} are immune to rot stink. Each detoxifier lung also increases Toxic Environment Resistance, so if a pawn only has 1 artificial lung, the other one will be partially protected.

== Stages ==
These are the following stages in which lung rot will progress through, and the effects it has on the victim. Note that the effects are generally doubled as lung rot usually occurs in both lungs at the same time.

=== Progression ===
*Severity increases by 0.300 per day.
*Treatment slows progression by a maximum of 1.000 per day.
**This means the disease will regress by 0.700 per day at 100% tend quality.
**Progression will pause at 30% tend quality or higher.
**Note that good treatment will not cause the disease to go away on its own.

The disease resolves after 6-8 days, independent of the patient's immune functioning.{{Check Tag|Fact Check|Does it depend on immune functioning?}}

== Treatment ==
Treatment can be done using medicine which suppresses the disease, preventing it from reaching fatal stages. Pawns do not need to rest, as no immunity is gained.

As long as it is tended by a decent doctor, lung rot isn't particularly threatening to a pawn's life. The real downside is the time and/or medicine consumed for treatment, especially if many pawns get lung rot at the same time. It is possible to reach >30% tend quality even without medicine, if you have a good doctor and hospital setup.

== Version history ==
* [[Version/1.4.3523|1.4.3523]] - Added.
* [[Version/1.5.4062|1.5.4062]] - Rotstink exposure now causes lung rot in Core. Previously the effects were defined in Core, and the [https://store.steampowered.com/news/app/294100?emclan=103582791454681671&emgid=3294970071159733465 Steam announcement] for Update 1.4 mentioned it as a Core feature, however rot stink exposure and lung rot would not be applied without the [[Biotech DLC]].
