A. The best way to prevent the spread of infections and decrease the risk of getting sick is by washing your hands with plain soap and water, advises the Centers for Disease Control and Prevention (CDC). Washing hands often with soap and water for at least 20 seconds is essential, especially after going to the bathroom; before eating; and after coughing, sneezing, or blowing one’s nose. There is currently no evidence that consumer antiseptic wash products (also known as antibacterial soaps) are any more effective at preventing illness than washing with plain soap and water. In fact, some data suggests that antibacterial ingredients could do more harm than good in the long-term and more research is needed.
