the developers of video game World of Warcraft – accidentally unleashed a plague. The hugely popular online role-playing game takes place on Azeroth, a virtual world with densely packed cities separated by stretches of open country, along with relatively unexplored areas like jungles and caves. Earlier that day, a new software update had granted millions of players access to Zul’Gurub, a new jungle-like area of the game world intended for those with relatively powerful characters.To get more news about buy wow items, you can visit lootwowgold official website.

The heart of this new section was a duel with a winged serpent called Hakkar, a powerful foe with the ability to infect player’s characters with a disease called Corrupted Blood, which would then be passed on to other nearby characters. It was designed to make fighting Hakkar slightly more difficult by slowly draining a player’s health, but there were unintended consequences.

World of Warcraft gives players the ability to fast travel – they can move instantly from remote areas like Zul’Gurub back to cities, for example, to stock up on supplies. It meant that powerful players who had been infected with the virus were able to carry it to mass population centres before they died or were healed.

The spread of the virus was accentuated by two factors – like the bubonic plague, new outbreaks were started by in-game pets, which could become carriers. Players often put them into something like suspended animation before or during big fights to protect them, but when they came out of this state they started new outbreaks. The game’s non-playable characters – shopkeepers and the like – are basically impossible to kill, but they could still carry the virus, so they quickly became super-spreaders.

Corrupted Blood soon developed into a full-blown in-game pandemic. As the skeletons piled up in the densely packed auction house in the capital city, one player realised that this could be more than just an amusing anecdote.As well as being an avid gamer, Eric Lofgren is also an epidemiologist, and he realised that the way players reacted to Corrupted Blood could offer a valuable insight into how we can expect them to behave during the rapid spread of a real-world contagious disease.

That’s really crucial, because a lot of the models that scientists use to try and predict how a disease like Covid-19 will spread are built on assumptions about the way people will behave. But we’re pretty irrational creatures – few would have predicted, for instance, that fans barred from attending the recent Champions League football match between Borussia Dortmund and Paris Saint-Germain would gather outside the stadium anyway, or that Ukrainians would voice their fear at a quarantine centre being set up in their area by going to the quarantine centre and throwing stones at a bus carrying evacuees from Wuhan.

“Traditionally when we do computer-based simulations we know everything about the world,” says Lofgren, who published a 2007 paper on the Corrupted Blood outbreak with colleague Nina Hefferman. “The people in those simulations only act the way we tell them to act. Here we get the full view of human irrationality.”

There are echoes of Corrupted Blood in the way the coronavirus spread from remote to urban areas, and in some of the behaviour we’re seeing in the worst hit countries. For powerful characters, the disease was no more troubling than a common cold, so they just went about their daily lives – but ended up spreading it to areas where more vulnerable players quickly died from it.

Some tried to be “first responders,” Lofgren says, travelling to the epicentre of the epidemic and trying to heal players who were infected – but this often meant contracting the disease themselves and then spreading it – we’ve seen parallels of this with healthcare workers becoming sick and passing away due to a combination of the coronavirus and general exhaustion.

As news of the outbreak spread, some people logged on to the game to see what the fuss was about, and promptly became infected themselves. There were even isolated incidents of players deliberately trying to spread the virus – we haven’t seen that in the real world, thankfully, although NBA player Rudy Gobert was heavily criticised for deliberately touching microphones and recording devices at a press conference a couple of days before testing positive for Covid-19. Perhaps there’s another parallel. “You do get people who go to work even though they’re sick because economic circumstances demand it, or to not let down their team,” Lofgren says. “We are also seeing some people not taking it seriously, and wilfully ignoring the risk, which is parallel to intentionally spreading it.”

Although Lofgren doesn’t remember seeing much evidence of stockpiling (no runs on virtual pasta), Corrupted Blood did have a wide impact for several days. “The capital cities, which were very densely populated and the central social and economic hub of the game, became very hard to live in,” Lofgren says. “There were some fairly significant disruptions to the economy of the game.”
