What is the expected outcome of using soap and water to clean hands?

Using soap and water to clean hands primarily results in a reduction in bacterial count. Soap works by emulsifying oils and dirt on the skin, which helps lift microorganisms away from the skin's surface. When hands are washed thoroughly, the mechanical action of scrubbing, combined with the emulsifying properties of soap, dislodges bacteria and other pathogens, allowing them to be rinsed away with water.

While complete sterilization of the hands is typically not achieved through this method, the reduction in bacterial load is significant and effective in preventing the spread of infectious diseases. Also, while soap may have some benefits for skin health, the primary purpose of washing hands with soap and water is to decrease the number of harmful microorganisms present, making this the expected and correct outcome.
