Disease N' Decease
Disease N' Decease adds new illnesses to Minecraft, so a player who touches certain plants can become sick and stay that way until the illness is cured.
What it does
Two plants spread the diseases in this Fabric mod for 1.21.1. Virelyss Bush generates in Plains and Sunflower Plains biomes, and touching it gives an entity Anemia, a condition that stops the entity from healing. Bloom Blossom generates in Swamp, Jungle and Dark Forest biomes, and an entity that steps on and breaks it gets Bloomlung, which damages the entity unless it is breathing as if swimming.
Bloomlung deals only modest damage, around 16 in total over its effect duration, and it ends once its timer runs out. Both conditions are meant to make the player feel sick in a literal sense rather than only as a label. Every player and the server need a copy of the mod. Files are published for Fabric only, for 1.21.1, with 0.2.0 as the latest file from 2025-07-14. The code is under the CC0 1.0 Universal license, which places the work in the public domain.
Key features
Anemia from Virelyss Bush
Touching Virelyss Bush gives an entity Anemia, which stops it from healing until the effect runs out.
Bloomlung from Bloom Blossom
Stepping on and breaking Bloom Blossom gives an entity Bloomlung, which damages it unless it breathes as if swimming.
Modest, timed damage
Bloomlung deals around 16 damage in total and ends when its duration runs out, so the illness is not instantly lethal.
Cure over time
Each disease lasts a set time, and the entity recovers once the cure time has passed.
