Coronavirus: How a misleading map went global
As scientists work hard to track and contain the coronavirus outbreak, misleading information about the global spread of the virus continues to flourish on the internet.
By Reality Check teamBBC News Here's how a decade-old map showing global air travel was used incorrectly by news websites across the world, leading to headlines such as "New map reveals no country safe from coronavirus tentacles" and "Terrifying map reveals how thousands of Wuhan travellers could have spread coronavirus to 400 cities worldwide." How did it start? Earlier this month, the World Population Project, at the University of Southampton, published research predicting where people from Wuhan, where the virus originated, had travelled to in the two weeks before the city went into quarantine lockdown. Researchers looked at air travel and mobile phone data of Wuhan residents from previous years. The study estimated nearly 60,000 people might have travelled to almost 400 cities worldwide before the Wuhan authorities had imposed a ban on travel. The researchers posted a series of messages about their work on Twitter, including one with a map illustrating global air travel. But the post did not explain the map was not part of the study. Some people responded and asked if the graphic - covered in red lines indicating world flight routes - represented the findings of the study. "No," the team clarified - it was part of a series of posts and intended to show the extent of the global air network - and deleted the tweet. But "somehow, from this, an incorrect story has spiralled", the university press office told BBC News. What happened next? The map seems to have first been picked up by several Australian news outlets. It has also appeared in the online editions of the Sun, Daily Mail and Metro. The Australian TV outlet 7News used the map in a discussion and posted a social-media video featuring it that has now been viewed more than seven million times. The report says the map predicts the spread of the global outbreak. The red lines, says the presenter, represent five million Wuhan residents who fled the city. In reality, the red lines just show flight routes around the world. And the five million figure comes from an entirely separate source. The mayor of Wuhan gave this number when talking about the total leaving the city ahead of the Lunar New Year holiday, most of whom would have stayed within China. What about now? 7News has now removed the map from its online article about the research. But it remains on many other news outlets' versions of the same story, in languages including Arabic, Russian, Polish and Vietnamese. And, perpetuating the myth, only last week a guest told US radio host Glenn Beck UK researchers had tracked the mobile phones of 60,000 people that had left China and then produced a travel map. "The chart is frightening," he said. Read more about the coronavirus and its impact Read more from Reality Check Send us your questions Follow us on Twitter
