As clean as it seems, most of our handphones are a lot dirtier than it seems. According to the article, whenever we board the train or any other public transport, we are bound to pick up many sorts of bacteria and many other wanted dirt and grime. Some of the dirt and bacteria include E.coli from fecal origin. When ingested, could cause horrible symptoms like fever, vomiting and diarrhea. Charles Gerba, a microbiologist at the University of Arizona, said that people don't usually clean their handphones very frequently. He also said that the amount of germs on a phone isn't a problem — it’s the sharing of phones between people. Without sharing, each phone carries just one set of germs, and won't get its owner sick.
