Health and Disease Mod

The mod adds 36 new diseases and 6 cancers, along with 36 new symptoms. Most diseases begin with early warning signs such as tiredness or malaise, and once an infection takes hold, a player may see a range of symptoms, from lesions and fever to a sore throat. Diseases are grouped into four types: bacterial, viral, amoebic and miscellaneous. The author states that the disease behavior is modeled as accurately as possible and that accuracy will improve with later updates.

Treatment is organised into four matching groups of medicine: antibiotic, antiviral, anti-fungal and anti-parasitic, plus palliative care. Palliative medicines such as acetaminophen and aspirin reduce pain and other symptoms, while symptom medicines such as modafinil target one specific symptom. The mod adds 61 medicine and treatment items and 7 blocks used to diagnose and treat disease. Three vaccines prevent infection with influenza, COVID-19 and lyssavirus, and the lyssavirus vaccine can be used after a bite from an infected wolf but before symptoms appear.

The mod is released under the MIT License, but it is not open source. It runs on Forge and NeoForge for Minecraft 1.20.1 and 1.20.6. Both the server and every player need it, because the health and disease systems apply on both sides. Its first public release was on 2023-12-17, and the latest file, 0.19.1, was published on 2024-10-02.
