This is a guide to vampirism in the elder scrolls IV: Oblivion. if you are already a vampire and want to cure yourself, go to the bottom and there is a link to the cure for vampirism walkthrough

There are some advantages and
disadvantages to becoming a vampire. To become a vampire, you must first get
the disease "porphyric hemophilia". Three days after getting the disease, when
you sleep, you turn into a vampire. You normally get the disease during fights
with vampires. You can also willingly receive the disease during the Dark
Brotherhood quests, just talk to Vincente Valtieri (before you get special
orders from Lucien Lachance).

You can stop the change to vampire by curing your porphyric hemophilia. Any
normal method of curing disease works: potion, spell or Activating an altar in
one of the Great Chapels in a city. You can greatly reduce the chance of
getting porphyric hemophilia by engaging vampires at range. They can't infect
you unless they use melee attacks against you.

Once you are a vampire, there are four stages of vampirism: 25% vampire, 50%
vampire, 75% vampire and 100% vampire. You begin at 25% (stage 1) vampire.
Every few days, if you don't drink any "human" (human in this case includes
Elves, Argonians and Khajiit) blood, you move to the next stage of vampirism
if you rest (Wait) or sleep.


Drinking human blood moves you back to stage 1 (25%) vampirism. You drink
blood by finding a sleeping NPC and Activating the NPC. You'll be asked if you
want to feed. Feeding on an NPC doesn't wake and doesn't harm the character.
You can feed on beggars, your maid in Skingrad (if you're rich), fellow Guild
members or even the Countess of Anvil (if you can break into the castle).
Don't feed where any awake characters can see you, or they will raise an
alarm.

During each stage of vampirism your appearance changes. At stage 4 vampirism,
your "condition" has become so noticeable most NPCs won't talk to you. You
can't shop, get quests or anything else. You can use the Vampire's Seduction
power to increase the target's Disposition so you can talk to the person. You
can also use standard Charm spells, scrolls or the Imperial race's Voice of
the Emperor power.

Beginning with Stage 2 vampirism, you can't Fast Travel during the day. You
can Fast Travel at night, but you'll need to make short hops. On foot, Fast
Traveling from Cheydinhal to Anvil takes 11 hours; if you have a fast horse,
you can cut that to 5 hours. So, on horseback, you can Fast Travel clear
across Cyrodiil in one night; on foot you'll only be able to travel about
halfway across the country.

By Stage 4 vampirism, being outside during the day will require that you run
along with a healing spell ready, casting almost constantly. You will not want
to stop and fight in this condition, so traveling through the wilderness
during the day can be quite dangerous. Keep an eye on the clock (shown on the
map/quest screens of your journal and on the Wait menu) and don't go outside
during the day. If you've been plundering ruins and dungeons, stay in the dungeon until nightfall
(which the game defines as 8pm), and then you can Fast Travel to the nearest
city. Wait in an Inn until daylight, then sprint for the stores to sell off
your loot.
