Lung rot

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" 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.^[Mechanics?]

Prevention

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

In the Biotech DLC, face masks, gas masks, and other sources of Toxic Environment Resistance all reduce the severity of rot stink.

Detoxifier lungs 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.

Stage	Begins at	Symptoms
Lung rot (minor)	0 - 0.59 severity	+5% Pain −5% Breathing
Lung rot (major)	0.6 - 0.84 severity	+5% Pain −10% Breathing
Lung rot (Extreme)	0.85 - 0.99 severity	+10% Pain −15% Breathing −10% Consciousness
Lung rot (Extreme)	1.00 severity	Death

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.^{[Fact Check]}

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 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 great doctor and hospital setup.
