The reporter observed that more and more public rooms have cancelled hand-washing papers and used mobile phones instead. However, the COVID-19 epidemic has come, and there have been continuous real-time experiments in China and abroad. After drying double hands, the number of colonies increased around them is obviously more than using hand-washing papers. Many people are worried that "it is more dirty when baking". They will stay away from the drying phones, forming a waste of equipment and examining the decision of public rooms management units.

Using a mobile phone to dry is more cost-effective than using hand-papers to wipe paper, but in the past two years, there have been continuous experiences in foreign countries that the ratio of using a mobile phone to wipe off bacteria is about three times that of a mobile phone. The Taipei City Environmental Protection Bureau also quoted research from Riz University in the UK, pointing out that after using a mobile phone, the amount of bacteria around 1 meter increased by 6 to 27 times, and the air gel produced by the mobile phone will stain the surrounding environment. It is recommended that "the hospital's bathroom is not suitable for using a mobile phone."

There is the scientific nature of the experience of drying mobile phone operators, and some practitioners say that the brand of drying mobile phones is also a key and cannot be discussed in general; however, some public mobile phones have poor maintenance management, such as filter networks that are not regularly replaced, and the wind will be more dimmer.

Kaohsiung City Datong Hospital also conducted a test. Shen Fengcheng, director of the security department, said that the number of bacteria in the exposed part of the hand paper is only 24 units (RLUs), and the high standards of 250RLU in the surgery room and the ward of the ward are still within the qualified range. However, the number of cyclone colonies in the hand-wiping paper rack is as high as 2865RLU, which becomes a cleaning mouth. Although it is reduced to 55RLU after disinfection, in order to reduce public doubts, most of the hospital hand-wiping papers have been changed to pull-down extraction.

Datong Hospital also tested that after using a mobile dryer, the average number of colonies on the hand was still 525 RLU, exceeding the standard value of 500 RLU in the general ward; the average number of colonies after drying with hand paper was 103 RLU, a 5-fold difference, and the result was consistent with the past text.

Chen Dunjie, director of the Infection Control Office of Datong Hospital, said that the commonly seen concave drying mobile phone, when the user puts his damp hands in and bakes, the moisture will drip to the bottom and accumulate, which is most suitable for the breeding of bacteria. When the hot wind blows out, the bacteria will spread. On the contrary, the old drying mobile phone with the hot wind blows down will not have water problems.

The politician government has previously reported that there were many cluster infections of new coronavirus pneumonia, which have been predicted to be cross-infected in restaurants and public rooms. Especially when people enter the bathroom, they often relax and take off their masks to make it easier. Chen Dunjie said that this is a big break from epidemic prevention. After washing hands thoroughly, don’t touch the items in the bathroom. After leaving the bathroom and before eating, it is best to disinfect your hands with alcohol.

The Taipei Municipal Environmental Protection Bureau recommends that public housing management units add ultraviolet lights or nanosilver germs in the public housing exhaust gas exchange device. Li Mengjie, a professor at Taichung University of Science and Technology, suggested that in the future, mobile phones should be designed with self-cleaning function and relied on internal UV lights, ozone and other methods to sterilize existing mobile phones, which should be frequently wiped and disinfected with alcohol or dilute bleach.
