If you thought that the germ-richest place in your house was the bathroom or the door handle, well, you were wrong. Because the award for the most polluted object goes to your smartphone! This is evidenced by several scientific research, such as the 2012 study performed by a group of researchers of the University of Arizona led by Dr Gerba, or the work of a team of Estonian scientists (Koljalg et al, Germs, 2017) or a more recent research carried out by Slovak scientists (Koscova et al, Int J Environ Res Public Health, 2018).
Dr. Gerba, in particular, has observed that on the surface of our smartphone we can find a number of bacteria ten times higher than that found on a toilet seat. In fact, while the toilet is cleaned often the smartphone does not. On the contrary, it passes from hand to hand, other people besides us can take it and in this way other bacteria migrate on our phone. From there, it's easy for our hands to become infected and we can get sick. But what are the germs found on a smartphone? These range from staphylococci, especially Staphylococcus Aureus, the main cause of skin infections such as boils or folliculitis, to the bacterium Micrococcus luteus, responsible for pneumonia in weaker people, or even, to a lesser extent, Escherichia coli. Not only that, especially if you work in a hospital or if you have been there, you can find Acinetobacter baumannii or Pseudomonas aeruginosa on your smartphone, the cause of infections in case of poor immune system. So, our smartphone is a receptacle for bacteria, but now that we know this, what can we do? The smartphone should be disinfected often. As demonstrated, it is sufficient to use disinfectant wet wipes, the article mentioned commercial wipes based on chlorhexidine, to reduce bacteria. This disinfection has proven to be able to remove practically 100% of bacteria, especially of the Staphylococcus Aureus type, as well as all fungi and molds.
