Disease is widespread throughout Mundus and beyond. Tamriel has its fair share of diseases, many of them fatal. Diseases can be transmitted through contact with the afflicted or through fighting animals and undead. They can also be transmitted magically or through dart traps. Most common diseases can be cured by magic, blessings or potions. The diseases brought about by the Blight usually require special spells or potions to cure, but few survived the defeat of Dagoth Ur. Diseases can be resisted as well as cured; the Argonians are famous for their natural immunity to almost all disease. Certain diseases such as Corprus and Porphyric Hemophilia cannot be resisted. Peryite is the Daedric Prince of Pestilence and therefore most diseases are under his domain.

Corprus, meaning skin blight in Ald Chimeris, is in Morrowind a name used for any of a number of ailments affecting the skin. The Dunmer are especially susceptible to skin blights for reasons unclear to healers. They range from mild annoyances to destructive plagues that can lead to disfigurement or death. Corprus maladies can have natural and unnatural causes. Natural corprus afflictions are caused by unsanitary conditions, unbalanced humors and parasites. Examples of such natural afflictions include inflammation, discoloration, the flaking and sloughing of corrupted flesh, or an outbreak of blisters or ulcerations. During the Interregnum, a house healer dedicated to studying corprus afflictions found that the best method for avoiding most corprus blights is to bathe often, wear clean clothes, and consume clean, pure food.
Unnatural causes of corprus blights include those of magical or alchemical nature. One such example is the Flay Blight of 2E 565, wherein hundreds of Dark Elves on the western shore of Vvardenfell contracted rashes that caused irritated, blotchy skin. The Flay Blight was caused by a change to the alchemical formula of a popular face cream of the time.
During the Third Era, the term "corprus" became especially associated with the so-called Divine Disease, which was the most terrible of the ailments associated with the Blight. The infection was created by Dagoth Ur and spread by contact with a corprus beast or by a specific curse. It destroys the mind of the sufferer and grotesquely deforms the body. It is not known how the transformation of Sixth House cultists into Ascended Sleepers and other monsters is related to Corprus. Some of the physical effects are similar, but the cultists remain lucid and attain a higher spiritual state whereas more mundane sufferers become mindless husks, like the common undead raised by necromancers.
Perhaps the most frightening aspect of this form of corprus is that it is completely incurable. Those infected were sent to Tel Fyr to live in the Corprusarium, where they were treated and studied by Divayth Fyr, a 4000-year old wizard working to uncover the nature of the disease and create a cure. Fyr had a theory that the Divine Disease is in fact not a disease, but rather a divine blessing that most mortals can't handle, pointing to the fact that the victims are completely immune to other diseases and don't age.
The last known Dwemer, Yagrum Bagarn, was infected with corprus atop Red Mountain during his exploration of Tamriel. He sought refuge at the Corprusarium in Tel Fyr, where he offered his knowledge and provided theories on the disappearance of the Dwarves.
In 3E 427 the Nerevarine became infected with corprus, and Divayth Fyr provided a "cure" for the disease. This "cure" did not actually cure the disease but rather removed the negative effects, such as crippling physical deformities and insanity, while retaining the positive effects, including immunity to all diseases, increased strength and endurance, and possibly also immortality.
The Crimson Plague is a dangerous common disease which spreads easily and acts quickly. Symptoms include weakness and headaches. Infection can result in muteness. The disease, once widespread across Tamriel, was thought to have been stamped out during the Second Era. In 3E 427, the tomb of Gedna Relvel in the ruins of Old Mournhold was unsealed. Relvel, once a powerful sorceress condemned for studying and practicing forbidden magics, had cheated death and become a lich. She then attempted to spread the Crimson Plague throughout the city of Mournhold by infecting rats with the disease. The lich was destroyed by the Nerevarine before the disease could spread to more than a few people.
Dampworm is common disease with serious effects. Symptoms include uncontrollable muscle spasms and twitching. It may be contracted from deer and nix-hounds.
Dementia is a hideous disease which slowly robs the victim of their intelligence, willpower, and even personality.

A repulsive disease associated with Namira. Victims of Leprosy slowly waste away, unless a cure is provided.
The Llodos Plague is a contagious disease that turns victims into violent husks. The time it takes to corrupt a person's ability to think depends on the strength of the sample they are exposed to. The disease spreads through physical contact with a victim, and can also become airborne, though it is only infectious over a few meters before it disperses. The disease originated in Serkamora but has subsequently spread across the region of Redolent Loam to Narsis and Muth Gnaar monastery. It was created by the Maulborn as part of a plot to end the worship of the Tribunal.
Noxiphilic Sanguivoria is a strain of vampirism that was common during the Second Era. Unlike other vampiric diseases such as Porphyric Hemophilia and Sanguinare Vampiris, vampires of the Noxiphilic Sanguivoria strain are not weakened by daylight, but are instead strengthened during the night. Vampires of this strain can undergo a complete blood transfusion ritual known as the Rite of the Scion to become Scions, a more powerful version of a vampire. The Rite of the Scion is also necessary for a Soul Shriven to become a vampire.
A rare virus that is described to harden the skin like stone or oyster shell. It also causes blindness and eventually drives the victim to insanity. It is speculated to have been created by the Sload after a merchant fleet was shipwrecked on a Sload island during the mid-Second Era and the entire crew became infected. Thought to be curable by turning the infected into a vampire, provided that the virus has not progressed far enough.
The Plague is a very serious, often fatal disease. Very quickly it will spread through the victim's system. Few who contract it live for more than a few days unless they are cured quickly. The Plague has been known to wipe out entire cities.
Known as the "vampire's disease", Porphyric Hemophilia will become vampirism after a three day incubation period. By itself, the disease affects the victim's stamina, but on the third night of infection the victim will die and become undead. The disease can easily be cured within the three-day period, but vampirism is notoriously hard to cure. The disease is similar to the less-common Sanguinare Vampiris and Noxiphilic Sanguivoria.
Rabies is a serious disease which leads to madness and eventual death. It can be contracted from rabid wolves.
Rattles is a mild common disease affecting a victim's willpower and dexterity. Symptoms include muscle spasms, listlessness and poor stamina. It may be contracted from nix-hounds, zombies and chaurus.

Sai's Affliction is a disease caused by excessive worship of Sai, the God of Luck. Sufferers of the disease have been abandoned by Sai, and long for the god's presence. They are driven to incessant gambling, seeking proof of the god's favor. This usually leaves the victim in poverty or debt.
Similar in nature to Porphyric Hemophilia and Noxiphilic Sanguivoria, victims of the less-common Sanguinare Vampiris will become vampires after a three day incubation period. By itself, the disease negatively affects the victim's health, but on the third night of infection the victim will die and become undead. The disease can easily be cured within the three-day period, but vampirism is notoriously hard to cure. Sanguinare Vampiris is found in the province of Skyrim.
Sanies Lupinus, also called Canis Hysteria, is contracted from lycanthropes, and causes drowsiness. However, after a three day incubation period the victim will become a lycanthrope (the type of which depends on the creature that caused the infection). The disease can easily be cured within the three days, but lycanthropy can only be cured by ritual.

"It was ever present, ever penetrating. It seeped into every person, every creature, every drop of water, seeking to be quenched. The afflicted drank themselves to corpulence with each passing day, until their bones cracked under their bulging flesh." — Kinlord Nemfarion
The Thrassian Plague (called slug famine by some ancient texts) was an artificially-created pandemic of mass proportions that occurred in 1E 2260, and the first known historical event to happen after the Dragon Break. It is estimated that half of the population of the Iliac Bay, and even Tamriel as a whole, perished because of it. It was created by the Sload and received its name from their homeland, the coral kingdom of Thras.
