A small mod to give you contagious diseases that cause epidemics in fortresses, plagues, developmental disorders (blindness, midgets), psychiatric conditions and medicine in fortress mode and for adv mode NPCs. Free for use and compatible with most everything, I imagine.

DFFD: http://dffd.wimbli.com/file.php?id=7818
(old, more complex and buggy version: http://dffd.wimbli.com/file.php?id=7758)
Major update! See: http://www.bay12forums.com/smf/index.php?topic=127265.msg4322030#msg4322030

I was playing adventure mode with this mod when I cam across a camp of human bandits.  The archer was a midget, the maceman was a giant, and the swordsman captain was blind.  It certainly gave their crew more flavor than any other nameless, faceless bandits, but what I didn't realize was that one of the pikemen was a Ghastly Plague Bearer.  He infected me as I was chopping his arms off, which was disappointing because I wanted to retire my dwarf and relocate him to a fortress I would start up later. 

In fortress mode, I had a mother give birth to her child, who was infected with meningitis. I locked them in their room with some food and drink and watched them constantly re-infect one another for five years, until the baby grew up to become a child and I could separate the two and let the disease die out.

In another case of fortress mode, I had a migrant wave bring a case of the flu with them. I quarantined them for 29 days instead of 30, then let them into my fortress.  The fps fucking crashed as 80+ dwarves all began to simultaneously infect one another CONSTANTLY.  I locked everyone into their respective rooms and waited out the disease.  30 days after I locked the final dwarf away, I had lost about 60% of my population to starvation, thirst, and insanity, including my Legendary Blind Weaponsmith.

In conclusion, I love your mod.

Haven't posted here before, and sorry if this is presumptuous making a new thread for such a little thing or anything. I just didn't find any "disease" mods with a quick search, and liked the idea personally.

Here's four contagious diseases for dwarf mode, also discoverable in adventurer mode. Use for your enjoyment or whatever you like, including inclusion in your own mod without credit if you want to - I just wanted to add new functionality to the game.

Summary:

Deities occasionally curse intelligent creatures to become plaguebearers. These otherwise unremarkable poor souls then migrate to and spread plague (by touch) in your fort. Plague victims experience different effects over time, but at this time will never completely recover from the plague. Plague sufferers can infect one dwarf per day to share the same fate. They will also infect your enemies and can be weaponized, as those enemies then infect other enemies. Unintelligent creatures can get and spread rabies instead.

Currently includes the following:
* bubonic plague - despite how it sounds, mostly harmless -- just blisters, fevers, vomiting blood and dizziness
* contagious manic depression - makes dwarves periodically emotionless and drowsy, mischievious or occasionally berserk
* blackheart plague - the money plague, causing oozing, nausea, blindness, random rotting of body parts and limbs over time and pain intense enough that dwarves can pass out
* rabies - an animal becomes contagious to both dwarves and other animals after three weeks, and permanently berserk at four weeks. A dwarf becomes berserk and contagious at four weeks and dies at five weeks.

DFFD: http://dffd.wimbli.com/file.php?id=7755

A more fun mode where EVERY dwarf is a potential plague spreader instead. This is done by modding creature raws so that dwarves all have a 1% chance to turn into a random type of plaguebearer. Note that without this divine laziness may cause you to never see a plague at all, while this all but guarantees it every time. Here:

DFFD: http://dffd.wimbli.com/file.php?id=7756

Unless I somehow uploaded the wrong raws, it's tested in arena mode to make sure syndromes work correctly and worldgen-tested. Not tested in fortress mode for balance at all, but from arena mode testing it seems plagues get very serious very fast if not contained.

If anyone wants it, I can also very easily make "medicine" that can remove plagues based on this. For anyone who's interested, just add IT_CANNOT_HAVE_SYNDROME_CLASS:MEDICINE to all the plague interactions and SYN_CLASS:MEDICINE to all your medicines.

No offense to anybody affected by a psychiatric disorder intended - the colorful vocabulary is supposed to reflect dwarven concepts of mental illness, not ours.

Spoiler: Long story (click to show/hide)

I was making a "Dwarf Souls" mod which was going to include lots of fun demons, dying things releasing edible "souls" that give you powers, plagues and insanity. Upon migrating my home computer to Debian (one of the best things I ever did, but...) I foolishly didn't realize to preserve my DF folder with all my modded raws, so there went among other things about a working week's worth of modded bodies and creatures with their dialog and interactions and everything.

I really don't feel like doing it all over again, but I didn't see any mod about illness and thought it was a fun idea, so I'm going to just rewrite and release that part of what I was doing, before I completely forget how to do all this again now that the project is gone. I'm still grieving over my poor demons though.

Spoiler: Old notes (click to show/hide)

EDIT: Some notes on how to modify this to your liking or apply this to your mod:

• To make milder and more severe plagues, just edit the syndrome tags that follow any plague at interaction: DISEASE_PLAGUE*
• To make new plagues that spread similarly, just copy a plague and change the plague number and the syndrome tags. They will work similarly to these. If you want to use the add on mod that makes plagues more common with them, the files are annotated so as to how to do that. Basically just add more options with your plague numbers and probabilities to PLAGUE_SWITCH
• To modify how plagues spread, modify the SPREAD_PLAGUE interactions. If you want them to not spread as aggressively, add a higher amount of time to the first [CE_CAN_DO_INTERACTION:START:1200] bracket (replacing 1200 with eg. 3600 for 3 days) and the immediately following [CDI:WAIT_PERIOD:1200] tags both. Adding to only the first one results in a higher latency period, but plagues spread very fast once started. Adding to only the latter one tends to create a domino effect, because while dwarves spread plague slower after they've started, they can still spread it to one other dwarf very fast if you didn't edit the first tag.
• To make a plague eventually end, should modify the [CE_CAN_DO_INTERACTION:START:1200] and [CE_CAN_DO_INTERACTION:START:0] clauses of its SPREAD_PLAGUE interaction, adding END:(desired time). The dwarf should now be plague-free and non-contagious in a month and ready to catch another plague. Also, to create a disease that spreads through your fort once only and then your dwarves turn immune to it, modifying the latter only as above should do it.

[Brilliand]

Masterwork Mod has diseases - I don't think dwarves who catch the disease are contagious, though, just dwarves who are born with it (yes, dwarves are born with the diseases).  Also, no Masterwork diseases are quick as devastating as the ones in your mod.

Is rabies spread through a ranged interaction?  I think it would make more sense (and be easier for the fortress to survive) if it was spread only through bites, like a werecurse.  Not sure whether that's possible to do in a general way...

[Halfling]

Actually all the diseases are spread at touching range with no usage hint, meaning that the AI will use them at any opportunity. Spreading plague can only target nonself while plague effects only target self. This is more realistic for rabies than just spreading it through bites, since it can be spread by creatures that are not fully rabid yet such as a dog infected with rabies licking you.

I'm not sure if rabies actually exists in the fortress mode world at this time, however, since it would require a creature to be cursed by a deity and then come to your fort and it's my understanding that animals are randomly generated upon entering the fortress mode map. An easy fix for that is to add rabies to animal raws, such as dog raws, in the same way as the "add-on" does, or to make a separate creature such as a "rabid dog" that exists in all desired biomes and can do the rabies interaction(s).

[Halfling]

Double post time! I felt that I had created a pretty solid framework here, so I set out to expand it some more and see what it can do. Turns out it can handle contagious disease, noncontagious disease and epidemics just as well. All that is needed is to copy the interactions and change the parameters. The raws below include annotation so as to how to do that.

New DFFD: http://dffd.wimbli.com/file.php?id=7758

Again free for all use you may have for it! Now includes the following:

Disease name - prevalence - spread - nature - effect

Plagues:

Black plague - approx. 0,03%/migrant - spreads 1x/day/diseased dwarf/touch - permanent, permanent immunity - intense pain, fevers, nausea, oozing and small chance of permanent eye, limb or organ necrosis per month (to death). Also small chance of a deity cursing someone with this.
Bubonic plague - approx. 0,03%/migrant - spreads 1x/day/diseased dwarf/touch - permanent, permanent immunity - blisters, fevers, vomiting blood. Also small chance of a deity cursing someone with this.
Hemorrhagic smallpox - approx. 0,04%/migrant - spreads 1x/day/diseased dwarf/touch - permanent, permanent immunity - bruising, coughing blood, bleeding (to death). Also small chance of a deity cursing someone with this.

Epidemics:

Influenza - 2,5%/migrant - spreads 1x/day/diseased dwarf/touch - lasts 1 month, preventable with medicine, no lasting immunity - fevers, nausea, slight pains all over
Meningococcal meningitis - 1%/migrant - spreads 1x/day/diseased dwarf/touch - lasts 1 month, preventable with medicine, no lasting immunity - fever and strong pain, chance of unconsciousness, tiny chance of psychosis
Pneumococcal pneumonitis - 1,5%/migrant - spreads 1x/day/diseased dwarf/touch - lasts 1 month, preventable with medicine, no lasting immunity - coughing blood, small chance of lung necrosis leading to death

Noncontagious diseases:

High blood pressure: affects 7,5% of dwarves - does not spread - permanent, treatable with blood pressure medicine - if untreated, 33% chance of dizziness lasting one month per month, 1% chance per month of cerebral infarction leading to permanent unconsciousness
Paranoid schizophrenia: affects 1% of dwarves - does not spread - permanent, treatable with psychiatric medicine - if untreated, 50% chance of vastly increased creativity for one month per month, 33% chance of no emotions for one month per month, 10% chance of psychosis for one month per month
Liver cancer: affects 1% of dwarves -  does not spread - permanent, liver necrosis can be prevented with cancer medicine - if untreated, liver will eventually undergo necrosis.

Other

Rabies: initially affects 1% of animals you give it to, can be given to animals only - permanent - affected animal starts spreading it by touch (1 victim/day) at 3 weeks, animal goes permanently berserk at 4 weeks; animal can infect dwarves after 3 weeks, dwarves go berserk and become contagious at 4 weeks and unavoidably die at 5 weeks.

Medicine:
MEDICINE_EPIDEMIC: stops epidemics spreading, which makes them go away. The only other way to survive them is to isolate dwarves so they don't keep re-infecting each other.
MEDICINE_BLOOD_PRESSURE: well, just about what you would expect. Makes dwarves not stroke out and become vegetables eventually.
MEDICINE_PSYCHIATRIC: keeps schizophrenic dwarves from acting on their delusions but also lowers their creativity
MEDICINE_CANCER: does not cure cancer, but makes it not destroy organs

All medicine currently works for 2 months per dose.

This is a minimal upload for compatibility. All the diseases are there, but you must add the 4 lines per disease category that are in ADD TO CREATURE and ADD TO MEDICINE to make creatures susceptible to disease and to make plants medical.

Comments, ideas, requests? 'Cause I could be persuaded to make more diseases too. (nurgleface)

Spoiler: Living with illness - pro tips for fortress mode (click to show/hide)

- To avoid migrants bringing communicable diseases to your fort, the easiest way by far is to build migrant quarters where they and their animals can be quarantined for 1 month before they are let loose in your fort. However, note that if their race is affected by disease, merchants and invaders can bring epidemics to your fort too! Strategic merchant containment is also a possibility, and may even be safer for you for other reasons as well - if they die of pneumonia they caught from your dwarves, you will get the blame (but also the goods, so there's that).

- You should be able to tell if an animal has rabies, because once it goes berserk, it and its corpse should be marked as "rabid". If there is a rabies outbreak in your fort, don't feel too bad. It will have infected at most 7-10 other creatures unless you were really unlucky. Isolate everyone who was in contact with that animal, and observe them for 1 month. Some will die, but because rabies becomes contagious very slowly, there should be no further casualties.

- Now that there are diseases, large and well-stocked hospitals are a thing. Hospitals should have plenty of medicine, wards where disease-bearing dwarves can be contained and observation chambers for dwarves who were in contact with a rabid animal. For epidemics, lock everyone in the infectious disease ward and feed them medicine until the epidemic has stopped. Unless you made wine lower blood pressure or are really good at micro, you'll also probably eventually have a collection of dwarves who had a stroke (but the chances of stroke are only 0,075% per month per dwarf, so not too many). Consider magma-based euthanasia unless you really love those dwarves. Important dwarves who you know have blood pressure could have their own chambers have stockpiles of blood pressure medication.

- The same goes for asylums. Schizophrenic dwarves should have their own little fort stocked with medicine so they can live relatively normal lives. However, since their occasional bonus creativity improves item quality, you may instead take the risks involved and let them live among your dwarves normally, preferably working as craftsdwarves - but they may eventually do something unwise. It's not particularly humane, but if you surround their craftsdwarf's workshop with cage traps, you'll most likely catch them if/when something goes wrong and can release them once they come back to their senses.

How do you administer the medicine in practice? Make food items have medical powers and just hope/jump through hoops to make sure that a given dwarf can only eat the one thing?

[Godlysockpuppet]

Maybe make demons capable of inflicting disease upon your fortress? I.e the angel of decay, or a demon of pestilence/blight?

[Halfling]

Yes, that's the idea. Although I would personally make them drinks instead. You can basically add the "medicine syndrome" to anything you want, so you could also make, say, a reaction that generates gas that acts as medicine, although that's very convoluted.

To make it not insanely hard, you'd probably want the medicine to not be very inaccessible. Either that, or start dwarf hospitals - schizophrenic dwarves are burrowed somewhere and that burrow contains the only stockpile of antipsychotic drinks and no other drink. Alternatively you could make the medicines give a permanent curative effect by removing their syndrome's END: token

Maybe make demons capable of inflicting disease upon your fortress? I.e the angel of decay, or a demon of pestilence/blight?

Very easy here's a syndrome that makes a dwarf catch the black plague (and also become capable of transmitting it) by fast-forwarding him to a particular part of "plague switch":

Spoiler (click to show/hide)

[SYNDROME]
[SYN_NAME:Tainted with the black plague]
[SYN_AFFECTED_CLASS:GENERAL_POISON]
[CE_CAN_DO_INTERACTION:PROB:100:START:0]
[CDI:INTERACTION:SPREAD_PLAGUE_1]
[CDI:TARGET:A:SELF_ONLY]
[CDI:FREE_ACTION]
[CDI:MAX_TARGET_NUMBER:A:1]
[CDI:WAIT_PERIOD:900001]
[CDI:ADV_NAME:Spread black plague]
[CDI:TARGET_VERB:feel sick to your stomach:feel sick to your stomach:looks pale and sickly]

Just add that to... anything that you want to transmit it, be it creature, interaction or mushroom.

[Deon]

I suggest making animals spread rabies only when they actually bite, otherwise it's a bit too... much .

[Halfling]

Unfortunately I don't think that's even possible, because it would require (I think?) rabies adding a [SPECIALATTACK_* token to a creature and syndromes and interactions can't do that, I don't think. If it worked similarly to a werecurse you'd have to have a rabid creature with that token for them to turn into. Fortunately, rabies is really spread by animals that don't bite too, so I can claim this is more realistic

If rabies seems like it's a bit too much, you can make it very rare by editing the probs in rabies_switch (the probability of animal having rabies is the product of both probabilities given there), or just not define it for any creature.

As it is any rabid creature will only have 7 victims before it goes berserk and is noticeable, and it will take a long time before the victims become contagious. So the procedure for "vanilla" rabies should be something like: if you have a rabies outbreak in your fort - the originator creature should even be called a "turned rabid" creature - after it's dealt with, lock EVERYBODY and actually everything you are not 100% positive was not affected in observation rooms, wait 1 month and see who survives. This is pretty realistic procedure for a time before rabies vaccines.

Incidentally, does anyone know how diagnosis works? How these things work is they actually define sets of syndromes for diseases that diseased dwarves choose from each month. They have cool names like "is wracked by a violent cough" or "is losing their lungs to pneumonia" or something like "has suffered a stroke" or "is acting on a paranoid delusion" - will these ever be visible to a player, other than in arena mode? If so, how to assure it? Would make medical treatment easier.

[Godlysockpuppet]

I know it's easy to make, if I wanted to make one I would. I just thought you were looking for suggestions

[Halfling]

Sorry. Confused that with a request. My bad.

I figured I'll not make ready-made creatures or medicine items to go with this so it's not too gimmicky and can just be slapped on any mod or df itself while staying otherwise "vanilla", unless someone wants some for their use.

[evictedSaint]

Oh man, this is all just so cool.  I've never seen diseases implemented quite as well as you have.

Do you think you'll make more various diseases? It might be interesting to see "Useful" diseases, such as insomnia (adds [NO_SLEEP]) or just plain curious ones, like mutism (removes [CAN_SPEAK]).

[Putnam]

Add saliva to all creatures with the material templates; after that, have rabies add a syndrome effect that makes saliva spread the disease.

[Brilliand]

Add saliva to all creatures with the material templates; after that, have rabies add a syndrome effect that makes saliva spread the disease.

I suppose all bite attacks would be modded to inject saliva?

Can a single attack inject more than one substance?  (I'm thinking of a spider with rabies.)

[Hugo_The_Dwarf]

could just have the saliva secreted on the mouth (or whatever part is used for biting) no injection needed, of course rain and water will rinse off the "drool" spreading it everywhere (in which more drool will be made)

giving the syndrome [ENTERS_BLOOD] and [SYN_CONTACT] will make it so lathering or a attack that is edged and reaches "blood" will infect
