Research: hand digging the nose is susceptible to pneumonia

In the experiment, British researchers allowed the adults who were tested to get S. pneumoniae on their hands and then let them make “wet sniff”, “dry sniff”, “wet poke” . , “dry poke” and other actions that ordinary people usually do when they rub their noses. Victoria Connor, a clinical laboratory researcher at the Royal Hospital in Liverpool, said: “Research shows that hands can spread the bacteria, and items such as cell phones or children’s toys may also be a means of infectious bacteria.”

The study also found that the “wet sniff” and “wet stamp” spread more bacteria than “dry sniff” and “dry stamp”, indicating that the amount of bacteria seems to decrease after drying the hands with the bacteria sample.

According to statistics, about 1.3 million children under the age of five die every year from pneumonia worldwide. The researchers said that although the experiment was aimed at adults, the main purpose was to remind parents to pay attention to keeping their hands clean. Connor said: “It may be difficult for children not to dig their noses or lick their noses. But for parents, ensuring that their hands are clean and the surfaces of toys and other items are hygienic can reduce infections and reduce their chances of developing pneumonia.”
