Skyrim:Disease

Contracting a disease weakens specific skills or attributes of your character. Disease effects remain active until cured with a potion, garlic bread , or at a shrine, which can be found in most hold capitals. Unlike in Oblivion, there is no Cure Disease spell and it is not possible to contract diseases from beggars. One particularly notable and somewhat unique disease is Sanguinare Vampiris, which transforms your character into a vampire three days after contracting it if left untreated. Multiple disease effects stack together. Carrying a disease may cause NPCs to say that your character looks sickly or should go to bed, although Arcadia in Whiterun will say things like this even if your character is healthy.

There are a number of ways to contract diseases in Skyrim, perhaps most commonly by contact with a creature, animal, or even some NPCs. Most diseases can also be contracted through traps found outside throughout Skyrim or in various dungeons. For those diseases, the first ID in the following table is for the disease when caught from a creature, and the second ID is the trap-specific version. Although the physical effects of the two versions of the disease are the same, the descriptions are often slightly different.

Survival Mode
The Survival Mode Creation adds new and modifies existing diseases. They can be contracted via contact with creatures, animals, and NPCs. Left untreated, most diseases will progress from its base form to a Severe or Crippling form after 24 hours. Each form is associated with more severe symptoms.

Notes
Argonians and Bosmer both have a constant 50% Resist Disease ability.
Werewolves and vampires are both immune to disease. Thus, a werewolf can never become a vampire, and the opposite holds true.
In Survival Mode, Werewolves and Vampires are still immune from becoming each other, but are not immune to the new diseases added by the CC.
Spell Absorption provides protection against disease, thus the Bretons are at a natural advantage. In Survival mode, Spell absorption has a chance of curing a disease when it progresses to a more severe form.
Spell Absorption may actually make it worse in Survival Mode. When a disease proceeds to the next stage it can be absorbed, but the effects of the disease may still be present even thought it isn't shown in the Active Effects menu. A possible fix is to contract the disease again and let it proceed to the next stage and only then use potion or altar to cure it. Only then will all disease effects will wear off. 
Vigilants of Stendarr will cure diseases if asked to do so.
Shrines will cure diseases and confer a specific blessing.
Apparel with a Resist Disease enchantment will reduce the chance of catching a disease. Apparel that provides 100% disease resistance, such as the dragon priest mask Hevnoraak, will render you absolute immunity to diseases. However, this is not necessarily a license to act indiscriminately, since it does not protect against diseases that ignore resistances.
Other enchanted apparel, potions, powers, or blessings can provide temporary or permanent bonuses that can at least partially mitigate the effects of diseases.
