Billions of mobile phones are in use around the worldThey exist on every continent, every country, every cityresearchers reviewed research into how mobile phones carry infectious pathogens such as bacteria and viruses, which they believe are likely to be "Trojan horses" that promote community transmission in epidemics and pandemicsthis phenomenon of transmitting pathogens from mobile phones causes serious health problemsThe risk is that infectious pathogens can be transmitted by telephone within the community, in the workplace, including medical and food treatment facilities, as well as on public transport, cruise ships and aircraftat the moment, mobile phones are largely ignored from a biosecurity perspective, but they may contribute to the spread of viruses such as influenza and SARS-CoV-2SARS-CoV-2 is a new type of coronavirus that led to the COVID-19 pandemicresearchers reviewed all the studies that could be found in peer-reviewed journals, analyzing microbes found on mobile phonesThe findings were published in the Journal of Travel Medicine and Infectious Diseases56 studies that met the criteria of researchers in 24 countries worldwide between 2005 and 2019most studies look at bacteria found on mobile phones, and several look at fungiOverall, the study found that an average of 68 percent of mobile phones were contaminatedThis number may be lower than the actual value, because most studies only aim to identify bacteria, and in many cases only to identify specific types of bacteriathese studies were done before SARS-CoV-2 appeared, so no one was able to test itDetecting viruses is hard work (especially for RNA viruses, including SARS-CoV-2 and other coronaviruses), and researchers can only find one study to detect virusessome studies have compared the mobile phones of medical workers with those of the general publicThey found no significant difference in pollution levels contaminated mobile phones pose a real biosecurity risk, allowing pathogens to easily cross national borders viruses can survive for hours, days, or even weeks on the surface of an object If a person is infected with SARS-CoV-2, their phone is likely to be infected Viruses can spread from mobile phones to more people through direct or indirect contact mobile phones and other touch-screen systems -- such as airport check-in counters and in-flight entertainment screens -- may have contributed to the rapid spread of COVID-19 around the world cell phone is almost ideal for disease We talk to them every day, precipitating the microbes through the droplets We often take them with us when we eat, leading to the deposition of nutrients that help microbes thrive Many people use them in bathrooms and toilets, causing fecal contamination caused by the plume effect Even though cell phones come into contact with microbes, most of us carry them almost everywhere: at home, in the office, in shopping, on vacation They usually provide a temperature-controlled environment to help pathogens survive because they are kept in pockets or handbags and rarely closed most importantly, we rarely clean or disinfect them Nearly three-quarters of people have never cleaned their mobile phones, according to researchers( and unpublished While government agencies provide guidance on the core practices of effective hand hygiene, little attention has been paid to practices related to the use of mobile phones or other touch-screen devices people touch the phone an average of three hours a day, and super users touch it more than 5,000 times a day Unlike hands, mobile devices do not need to be cleaned regularly the researchers therefore recommend that public health authorities implement public awareness campaigns and other appropriate measures to encourage the disinfection of mobile phones and other touch-screen devices Without such efforts, the global public health campaign for hand washing may be even less effective researchers recommend that mobile phones and other touch-screen devices be disinfected daily using 70 percent isopropanol sprays or other disinfection methods these decontamination processes should be strengthened, especially in key service industries such as food processing businesses, schools, bars, cafes, aged care facilities, cruise ships, airlines and airports, health care facilities, etc We should always do this, especially during outbreaks of serious diseases such as the current COVID-19 pandemic References: 1
