Money

Currency notes and coins change hands several times a day, accumulating the dirt and bacteria from multiple people’s hands. A study found that a single currency note had 135,000 bacteria on it and another had 126,000. While you cannot avoid handling money, try to hold it in your hands for as little time as possible and wash your hands when you are done. Do not let your kids play with money or put coins in their mouths, for they could easily catch infections and fall sick.
