Your Cell Phone Is Covered With a Personal Bacterial Cocktail

Testing phones for bacteria and viruses could tell doctors who has been exposed to potentially deadly microorganisms

Our bodies play host to around 100 trillion microbes that together weigh more than 2 pounds. They are present on our skin, in our guts, in the crooks of our elbows, and just about everywhere else.

These bacteria, viruses, and fungi, collectively called the microbiome, help us digest our food and fight off infections. And emerging research shows that modifying our personal mix of microbes may even help treat chronic conditions like diabetes and Crohn’s disease.

To get an idea of just how many microbes we carry—and which ones—researchers are testing our most intimate possessions: our cell phones.

In a small study, University of Oregon scientists tested the index fingers and thumbs of 17 subjects, along with the touchscreens of their smartphones. As you might expect, they found an 82 percent overlap between the most common types of bacteria found on participants’ fingers and on their phones. Women tended to have more bacteria in common with their phones than men.

Of the more than 7,000 different types of bacteria the researchers identified, the most common were in the StreptococcusStaphylococcus, and Corynebacterium families. These bacteria are typically found in the human mouth and on the skin.

Though some strains of StreptococcusStaphylococcus, and Corynebacterium can make people sick, especially if they have a weakened immune system, research suggests that these bacteria help protect ­­­­the skin, in part by competing with harmful strains for space and resources.


Taking care of your hands hygiene will reduce potentially microbiome spreading to your body

If  you found that washing your hands everytime is too much. One of solution is sanitizing your hands, either you use sanitizer gel or wet wipes. It is more comfortable and easy to use wherever or whenever you are.
