Using mobile phones for communication in emergency departments is a common practice; however, several studies have demonstrated that they may act as vectors for bacteria and viruses. This study evaluated the effectiveness of plastic wrapping in decreasing bacterial contamination on mobile phone surfaces.
We used culture dishes and a luminometer to detect bacterial colonies and contamination on the phone surfaces.
Our experiment showed that bacterial colonies exist on mobile phones before and after work. We found that wiping with 75% alcohol sanitizers effectively reduces the number of colonies on either a mobile phone or a temporary plastic covering. In addition, we found that bacterial colonies do not contaminate or adhere to plastic wrap any easier than to mobile phones.
These results demonstrated the effectiveness of plastic wrap for protecting mobile phone surfaces against bacterial colonization. In addition, applying a layer of plastic wrap protects the phone from potential damage due to the alcohol.
在急诊科使用手机进行通讯是一种常见做法；然而，多项研究表明，手机可能成为细菌和病毒的传播媒介。本研究评估了用塑料包裹在减少手机表面细菌污染方面的有效性。
我们使用培养皿和光度计来检测手机表面的细菌菌落和污染情况。
我们的实验表明，上班前后手机上都存在细菌菌落。我们发现，用75%酒精消毒剂擦拭可有效减少手机或临时塑料覆盖物上的菌落数量。此外，我们发现细菌菌落沾染或附着在保鲜膜上的情况并不比附着在手机上更容易。
这些结果证明了保鲜膜在保护手机表面免受细菌定植方面的有效性。此外，包裹一层保鲜膜可保护手机免受酒精可能造成的损害。
