As the Chinese government continues its effort to slow the spread of the coronavirus, the country's central bank has told the media it is going to begin literally cleaning its currency. Currency is notoriously dirty. In fact a study of dollar bills in New York found 397 bacterial species living on the surface.
And when someone with the flu handles it, that virus has been shown to survive for up to 12 days. The World Health Organisation (WHO) has said it is still not known how long the coronavirus can survive on surfaces and objects, including money.
One method for cleaning money is to use ultraviolet light or high temperatures on it, then seal the cash away for one to two weeks before releasing it back into circulation. When possible, the Chinese bank said, it would provide brand new banknotes
