I think that Auri-El probably either tried but failed to cure Vyrthur, or just didn't care about him becoming infected, perhaps as a punishment for his big ego which I noticed when the DB and Serana confronted him.

But to be honest, I just wish that if you had a high enough speech skill you could convince Vyrthur to get cured by Falion, or become a werewolf if the Dragonborn is in the Companions so that the Dragonborn could give him a Glenmoril Witch Head and take him to Ysgramor's Tomb.
