If you use your phone in the restroom, hospital, market or other public places, there is a high chance that your device is highly contaminated.
In a 2011 study conducted at the London School of Hygiene & Tropical Medicine and Queen Mary, University of London, researchers measured about 400 cell phones for levels of bacteria. Shockingly, 92 percent of the phones had bacteria on them.
A 2009 study published in the Journal of Hospital Infection found mobile communication devices as potential reservoirs of nosocomial pathogens. Nosocomial pathogens are pathogens acquired in hospitals and other healthcare facilities.
Even a 2013 study published in the Journal of Perinatology reports that bacterial contamination of cell phones may serve as vectors for nosocomial infection in the neonatal intensive care unit.
The transmission of bacteria from cell phones to hands may not be eliminated using antimicrobial gels.
Another study published in the Journal of Bone and Joint Surgery in 2015 found orthopedic surgeons’ cell phones to be a potential source of nosocomial infection in the operating room and recommended cell phone cleaning more frequently than once a week.
So, disinfecting your cell phone is always a good idea to prevent the spread of germs to yourself or others.
