The researchers then investigated whether bacteria were present on the nasal mucosa after different types of contact with the hand. It turned out to be present, and in considerable quantity. And the most effective way of infection was considered "wet" by putting a finger in the nose. In the second place comes the "wet sniffing" of the back of the hand. The results of the "dry" shipping methods were not so noticeable, because in some dry environment some bacteria die off. Tests also showed that it is possible to get infected, not only to pick the nose, but simply wipe it with the back of your hand.
