In your adventure you will meet many vampires and you may receive the "porphyric hemophilia" disease from them while you're fighting with them. You can cure it with either a spell/potion cure disease or using an altar in a church.
If you don't cure the disease within 3 days, when you sleep you will slowly become a vampire. This change is irreversible after you sleep and will take some time to clear up as it involves a quest.

Notes[edit]
In second step you will begin to get a weakness to sunlight and it will be harder for you to go outdoors in daytime. Eventually it will kill you even if you only wait an hour in sunlight, With fourth step vampirism, sunlight can burn you into ash for a short time, people that see you won't talk to you and merchants won't trade with you if their disposition isn't high enough. You can't use the fast travel function while getting burning or in you can you may end up dead because you arrived there in daytime but if you want to enjoy daytime there's a way: you have to suck NPC's blood by sneaking into their house and pressing activate on them (normal key/button for talk) while your victim is sleeping and choose the "feed" choice, when you do this, you will shortly return to the first sages of vampirism. Remember that you can suck their blood only when they're sleeping and blood sucking is crime (assault)
A Vampire Cure[edit]
To start, you will need to talk to a priest or Vincente Valtieri of the dark brotherhood, it is best to talk to them both if you can as after you finish the quest you can still ask for a cure from Vicente even though you have cured it, making an uncompletable quest.
Note: If you have the PlayStation 3 Game of the Year edition, there is a major glitch that doesn't allow you to complete the quest to cure yourself of Vampirism. This glitch is only found in the Game of the Year edition for PlayStation 3—no other versions of the game have the glitch.
