Six out of seven cases – 86% – were not reported in China before travel restrictions were imposed, which according to a drives the spread of the virus study Monday in Science magazine.

“It’s the undocumented infections that drive the spread of the outbreak,” said co-author Jeffrey Shaman of Columbia University’s Mailman School. according to GeekWire.

Using computer models, the researchers tracked infections before and after the travel ban in the Chinese city of Wuhan.

The results showed that these undocumented infections with no or with mild symptoms – so-called “stealth” cases – were behind two thirds of the reported patients.

“Most of these infections are mild and have few symptoms,” said Shaman. Mercury News reported. “People may not recognize it. Or they think they have a cold. “

These “stealth” cases could then transmit the error that, according to the researchers, could cause severe symptoms in other people.

“It will continue to be a major challenge to contain this outbreak,” said Shaman, adding that it underlines the importance of restricted movement in hard-hit regions.
