In the realm of infection control and public health, the humble act of hand washing is a powerful weapon against germs.

Understanding the Science Behind Hand Washing

Hand washing is a physical process that removes microorganisms from our hands. It's not just about soap and water; the mechanical action of scrubbing and rinsing is equally important. This process disrupts the outer layers of bacteria and viruses, making them less able to cause infection.
