According to ArsTechnica, a virtual plague has gotten loose in World of Warcraft, the hugely popular online game:
The trouble started when Blizzard programmers added a ... separate area ... that players can enter and attempt unique quests. One of these instances, Zul'Grub, contained the god of blood, Hakkar. Hakkar was a powerful foe that could cast spells of his own, including a spell called Corrupted Blood. This spell did a large amount of damage to any player within the vicinity....
What happened next was something Blizzard did not expect. Some of the players who had gone into the instance emerged back into the main world of Azeroth, and started spreading the Corrupted Blood disease to others who they came into close contact with. The infection soon spread into many of the cities and towns in the virtual world....
Instead of being angry about the deleterious effects of a bug, many are treating this as an exciting and unprecedented event in the WoW universe.
