Here are five thought-provoking reasons schools should consider banning the devices from their classrooms: Academic Performance Improvement According to a study conducted by researchers at the University of Texas and Louisiana State University, when schools forbid students from bringing their smartphones into the classroom, their grades quickly improve on the whole.
Mobile devices used in hospitals are of particular interest, as they have been implicated in the spread of nosocomial infections . Microbial contamination is most commonly found on the mouthpiece, although the earpiece and the handles of public telephones can also harbour bacterial species.
While indirect contamination from person to person has decreased with the decline in the use of public payphones, cell phones with buttons and keyboards and other personal mobile phones in general has been found to be even more conducive to bacterial contamination .
Physical Environment The majority of bacterial species that have been found on phone surfaces are those that are part of the normal flora of the skin and body, due to the constant contact with the hands and face.
The normal flora of the skin includes up to bacterial cells, the most common species being Staphylococcus epidermidis and Corynebacteria . In addition, bacteria found in the mouth and the upper respiratory tract can also spread through aerosols and droplets that are released while breathing or talking into the mouthpiece .
Many species are resistant to desiccation and can persist on phone surfaces for weeks, with gram-negative bacteria usually persisting longer than their gram-positive counterparts .
Despite this, actual colonization and growth of bacteria is rare due to the general lack of nutrients and moisture on the plastic and glass surfaces of phones.

The contamination rate of S. Acinetobacter baumannii Acinetobacter baumannii is a ubiquitous bacterium that can be found in the normal skin flora, as well as in soil and bodies of water, amongst others . It is a gram-negative coccobacilli, which are characterized by their truncated rod shape.
Some strains have also shown to be extremely resistant to desiccation, surviving for several months with little to no reduction in the number of colonies . SEM image of Acinetobacter baumannii. Staphylococcus aureus Staphylococcus aureus is one of the most common causes of nosocomial infections .
Methicillin-resistant Staphylococcus aureus MRSA is of particular importance in the medical community, as it has evolved resistance to beta-lactam antibiotics . However, their occurrence on phone surfaces has been shown to be relatively rare compared to susceptible strains, with a higher rate of occurrence amongst phones in the hospital than on personal mobile phones .
Implications on Nosocomial Infections The rise of the use of mobile phones has surprisingly important implications in the microbiology and medical communities, most notably in the area of nosocomial infections. While some hospitals have banned them for this reason, mobile phone use is still relatively commonplace, even in operating rooms .
Mobile phones, as well as other more documented items such as surgical equipment, stethoscopes, and clothing can act as a reservoir for bacterial growth or contamination. These items can then act as potential vectors, transferring bacteria onto susceptible patients through indirect-contact transmission.
However, while many of these items are subjected to very high hygienic standards, standard cleaning procedures or even guidelines for the use of mobile phones in hospitals have yet to be established .
Furthermore, there is also the risk of further transmitting nosocomial pathogens outside of the hospital if health care workers use the same cell phone for personal use. Decontamination Many studies    have reported that the majority of people, including health care workers, do not clean their mobile device.
This poses a potential risk factor, as many doctors and nurses not only carry their mobile devices with them, but some have also reported using them while observing patients . However, recommendations for proper cleaning have not yet been established as many phone manufacturers recommend against using alcohol to clean their phones.

Also, cell phones have a new function: text messaging. Physical abuse can be any kind of hitting, shaking, burning, pinching, biting, choking, throwing, beating, and other actions that cause physical injury, leave marks, or cause pain.
Sexual abuse is any type of sexual contact between an adult and anyone younger than 18; between a significantly older child and a younger child; or if one person. A student with a cell phone is an uninterested student, one with a short attention span who cares more about socializing than education.
When I was teaching, all too often I turned around from writing something on the blackboard to find students text-messaging or otherwise playing with their phones. The presence of a cell phone while two or more people are talking face-to-face can generate negative feelings toward the person who has his or her device visible.
In two studies conducted at the University of Essex in the United Kingdom, researchers studied the effects of a mobile . Somehow, that moose brought the neighborhood together more than a cell phone ever did.
