If you use another person's phone, 30 percent of a virus can make it to your fingertips just by touching the screen. If you rub your eyes, bite your nails, or put your hands to your face, the virus can get into your system. The information comes from a study from the July Journal of Applied Microbiology.
We're not saying you should stop playing with your friends' mobile phones or never let anyone touch yours. As we move into fall though, and with the flu season coming up, just keep the information in mind. Remember, there are plenty of other ways to spread the flu. Don't be paranoid about it; as long as your immune system is working, worrying about getting sick is probably more harmful than doing your best to use every single phone in sight while walking down the street.
