Blizzard is fast earning the reputation of becoming the worlds famous and most playing MMORPG. With a current population of 9-million and rising Azeroth is fast becoming one of the most populated virtual cities in the world. Now in spite of dividing them into realms, there are a huge number of players online players at any given instance. In real life the mixing of such different races into non-discriminatory and congested space would produce diseases, what with the Tauren blowing down upon the necks of Dranai and what not, astonishingly it is seen that a similar event has taken place. Players have been heard suffering form a disease known as Corrupted Blood in the September of 2005. Like an epidemic outbreak of Cholera or Black Death in the old times in Europe, this plague took the WOW denizens in its sick grip. Princeton University medical epidemiologist Nina Fefferman and her former student Eric Lofgren have extrapolated real-world implications out of this in-game demitragedy in a study just published in the medical journal The Lancet. It was found out, like any epidemic this disease spread through proximity contact, so players are advised to avoid “brushing shoulders” with the fellow brethren. The disease originated from a large-group encounter of Zul-Gurub. The symptoms include the draining away of hitpoints until the disease ran its course and with lots of healing one survived or ultimately death. The disease started with a few gamers who had a little too much time on their hands and decided to play naughty. Gradually broadening out it held most of Azeroth under its reign. As indicated by the research it was largely due to a behavior named as “stupid factor”. “Someone thinks, ‘I’ll just get close and get a quick look, and it won’t affect me,’” and just like that the disease gets a lift across the countryside. So this outbreak actually provided to be a basis of test gerunds for the medicinal facility so they now know what to expect when something who shouldn’t be where it is gets out of there and how to handle it. “Now that it has been pointed out to us, it is clear that it is going to be happening. But they have always been along the lines of what would happen if we put people into a quarantine zone–will they stay?” Fefferman added. “No one has ever looked at what would happen when people who are not in a quarantine zone get in and then leave.” So it seems that the world has now become aware of a new benefit of having an MMPORG of such immense proportions. “With very large numbers of players, these games provide a population where controlled outbreak simulations may be done seamlessly within the player experience,” she said. So the WOW players are advised to wash hands after having a PVP and keep an eye out for suspiciously ill-looking strangers.
