The Corrupted Blood plague
In 2005, World of Warcraft accidentally caused a virtual pandemic when a boss fight introduced a disease called Corrupted Blood. Players unknowingly carried it out of the dungeon and spread it through crowded cities, killing low level characters in seconds. Some players tried to help the infected, others deliberately spread it, and entire cities became death zones. The outbreak caused so much chaos that Blizzard had to intervene with server resets and patches. Epidemiologists later studied it as a model for how real pandemics spread.
