Necrosis spreads in several ways, and each method requires different methods to prevent it, which will be examined below.

Elder Mushroom Ingestion

Elder Mushrooms can be ingested in two forms, either ingesting the mushroom itself or ingesting the spores.  While the mushrooms are not typically eaten, there are the occasional dextroluma in the Blighted Wilds who do cook and consume them.  It is not impossible to think that one dextroluma might sneak them into a dish or a drink in some form or another, and there’s really no way to avoid infection if that happens.  The best bet is to be careful and know that these mushrooms taste sweet with a bitter aftertaste.

Ingestion of the spores is far more common, due to a weather phenomena in the Blighted Wilds known as ‘spore fog’.  The only way to protect against this form of ingestion if you encounter it is to wear a ventilator mask or to remain in an airtight environment until the spore fog has ended.

Bodily Fluid Ingestion

Obviously, bodily fluids come in several types.  For the three that are a risk for transmitting necrosis, some dextroluma have had success in taking the cure as a pre-exposure preventative, especially in regards to semen and natural vaginal lubrication.

Blood is the most likely bodily fluid to be able to infect another dextroluma, with a 99% infection rate.  Blood banks must test all donors for necrosis and most only accept blood from those who have never been infected, as even dextroluma with inactive necrosis (cured) are able to pass on the infection.  Beyond blood banks, a common and easy way for infected dextroluma to infect uninfected dextroluma involves cutting both their bodies to produce blood and mixing them, or forcing the uninfected dextroluma to drink blood from one of their wounds.

Semen is the next most likely bodily fluid to be able to infect another dextroluma, with a 56% infection rate.  If a partner has active necrosis (corrupt), it is recommended to always use a condom and lube - lube is particularly important, as micro tears in the vagina, anus, or cloaca raises the risk of contracting necrosis.  Dextroluma with inactive necrosis (cured) are unable to pass their infection on via semen after the first six months of taking the cure, and these precautions can be disregarded then - although of course, these are still important for standard safe sex.

Natural lubrication from the vagina is quite unlikely to transmit necrosis, with only a 3% infection rate.  Still, due to this risk, if a partner has active necrosis (corrupt) it is advised to use condoms, lube, gloves, and/or dental dams as appropriate.

Bodily wastes and saliva do not transmit necrosis, even from someone with active necrosis (corrupt).
