The problem is as a new player you don't know vampirism or 3 days or anything about the disease..before you have the full blown disease. Heck I had to go to a wiki and talk to players in forums to know what was going on. I will be frank...if my wife knew this was in the game she never would have bought it for me as a Christmas present. That's how much we don't like it.
Well, if you are a new player who cannot be bothered to read up on how to play the game and how to protect yourself from effects that you may find undesirable, then you deserve what you get, frankly. I would think that in the early stages of the game, ZOS will have conversations where you can be informed of how to protect yourself from Vampirism or Lycanthrope. Ideally this will be part of the player tutorial that so many "I know everything" players just blow through and don't bother to learn, then they pitch temper tantrums on the forum when they get owned by the game or by someone in the game.
Seriously. People really DO need to learn to play. And I don't mean that disparigingly
