A Tufts university researcher wants to use an incident in “World of Warcraft” to learn about how a pandemic might spread and people might react to it.
In the fall of 2005, Blizzard Entertainment, which created and operates “World of Warcraft”, introduced a new area into the game and in the area, a new villain who could infect players with a curse called “Corrupted Blood”, which caused a great deal of damage to the player over a short period of time, usually killing the player in short order. A very unusual effect of Corrupted Blood was that it could infect others standing near players who were afflicted by it. Leaving the area would clear the curse, but it turned out there was an accidental vector for it to travel outside of the new area, via pets belonging to Hunter characters. So, while the creators of World of Warcraft had meant for it to be contained in only the new area they’d added, it spread across the world and through the major cities. Players started avoiding the major cities and groups of other players in an attempt to stay clear of the curse.
