It is well known that winter brings with him some serious viruses, like influenza. And the easiest method to transmit viruses and microbes is: Money.
The study shows how long is the process that a money paper goes through before we get to use it. Additionally they shed the light on the fact that this same paper has rotated well enough to carry with it a wide number of serious viruses and microbes.
As a result, we should not put the money in our mouths or hold it for a long period of time. In addition, we have to sanitize our hands every now and then.
