How contagious are monster-based diseases?


Rules Questions

Many new monsters from the Bestiary II, such as the daemons, inflict various UNIQUE diseases through their attacks and other abilities.

For example, the Meladaemon inflicts the following disease whenever it hits with a bite attack and the victim fails its save:

Daemonic wasting: Bite—injury; save Fort DC 23; onset 1 day; frequency 1/day; effect 1d4 Con and 1d4 Cha damage; cure 2 consecutive saves. The save DC is Constitution-based.

But is it really all that contagious?

If a victim falls prey to daemonic wasting, can it then spread the disease to others via a bite?

It would make sense for this daemon to bite a dog or similar creature and setting it loose in a populated area, thereby giving it the disease and making it supernaturally hungry so it is forced to go out and bite others in search of food, the victims of of which then go on to repeat the pattern.

Zombie apocalypse anyone?

As a confirmed carrier of 134 diseases of non-human origin, twenty of which are only found in harpies, I have to answer "VERY".

They aren't by the rules, but I had a homebrew game beign made that had zombies that could create spawns. I think if monsters had contagious diseases many adventurers would have to spend a night outside the gates, or at least until the local cleric cleared them for entry. I never got to run that game, but one day.....


I don't think I'd want to keep track of it for every single thing that a "biter" bites, but honestly, its not a bad adventure hook. I seem to recall some older D&D sources mentioning common wolves that were carrying lycanthropy even though they were just normal wolves because they were bitten by werewolves.

I don't know. These are the Paizo boards and staying on topic is unthinkable.

I also like what Knight said about using spreadable diseases as a plot hook. It's a classic.

Mostly because I don't see it going well if I opened it as its own discussion.


I can't see anything wrong with what Ravingdork said..

On topic: as far as RAW there is nothing I have seen mentioned in the books about how the diseases get transferred other than catching them directly from certain sources, so I would say that as far as what is written it just doesn't happen any other way, anything else is house rules. Curse Of The Crimson Throne has some rules as far as a widespread plague goes... Obviously it is an area that could be expanded on greatly.
Although as someone mentioned it is an area to watch out for as people could intentionally infect themselves with some things to try to gain a combat advantage....

RD,

I thought that you asked a good question. I think the attitude you've been shown here tonight has been - well, disappointing, [somehow the word "a&+#+%@ry" (donkey-vortex-ery) comes to mind]

To your question specifically. Lycanthropy comes to mind. If monster based diseases cannot be spread, then lycanthropy should never be a problem. Only "patient zero" lycanthropes who are given the disease by, I dunno, a deity maybe, should be able to pass on the disease. And then it would stop. Which would make were-creatures of any kind exceedingly rare.

Or, monster based diseases can be spread, and lycanthropy would be a continuing problem in any world setting. Which it appears to be.

I'm trying to figure out the logic of monster-based diseases not spreading. Imagine you have a toothy half-orc who is bitten by a sewer rat that has filth fever. He fails his save, and contracts the disease. The next day, still infected with the disease, he is affected by a confusion spell, and ends up making and hitting with a bite attack against a party member. I would think it entirely reasonable to have that party member make a save against the disease, or then contract it himself.

As long as the disease vector is consistent, and onset has occurred, I can't see why it wouldn't pass from one victim to the next.


I agree that not having diseases spread is not logical, my point was there just isn't specific rules on how contagious they are... It is definitely something that could use some fleshing out, maybe specifying which methods of transmission for which diseases/chance of infection/etc


As far as Lycanthropy goes, I thought only "Natural Lycanthropes" (i.e. born a werewolf) could spread the curse. "Afflicted Lycanthropes" (i.e. someone bitten by a werewolf) could not spread the curse.

There is no distinction made in the rules. Which gets to what RD was asking about. It would be a nice thing if the mechanic was spelled out in game terms. Is there, or should there be a difference in transmission between a curse and a disease? If so, then how are the transmitting individuals different? (Different stats? Would a Knowledge check reveal whether one need worry about infection?)

Quantum Steve is correct in regard to lycanthropy:

Quote:
Curse of Lycanthropy (Su) A natural lycanthrope's bite attack in animal or hybrid form infects a humanoid target with lycanthropy (Fortitude DC 15 negates). If the victim's size is not within one size category of the lycanthrope, this ability has no effect.

The creature that naturally has the disease can spread it, but victims infected by the creature cannot spread it. Although, this is not just an ordinary disease. It is a curse too.

.
.
.
On a slightly different side of things...when the zombie rot of a plague zombie kills a victim, the victim turns into a plague zombie, and therefore, the zombiefied victim can also spread zombie rot.

Quote:
Disease (Su): The slam attack—as well as any other natural attacks—of a plague zombie carries the zombie rot disease.Zombie rot: slam; save Fort DC = 10 + 1/2 the zombie's Hit Dice + the zombie's Cha modifier; onset 1d4 days; frequency 1/day; effect 1d2 Con, this damage cannot be healed while the creature is infected; cure 2 consecutive saves. Anyone who dies while infected rises as a plague zombie in 2d6 hours.

But it doesn't seem like the infected victim can spread the disease. It is the zombie it turns into which can spread the disease.

Maybe the rule is that if you turn into the creature, then you can spread the disease. But I would think that the ability to spread the disease is because you are now this creature, not just because you are infected. And the lycanthopy template is an exception to this rule, which is why it states that only natural lycanthropes can spread this disease/curse... infected victims turn into lycanthropes but still cannot spread it.

Afflictions are not contagious unless it's explicitly spelled out in the affliction and as far as I know none of them are. Diseases are a type of affliction and follow these rules.

The 'disease' of Lycanthropy is not contagious, a person is infected with lycanthropy cannot spread it. If a person eventually becomes a were-creature they gain the were-template and the special ability to infect other creatures with lycanthropy. It's not the disease but the were-template that makes them able to inflict lycanthropy.
