Proper hand washing technique can help prevent over 1 million deaths per year from diseases according to the CDC. Correct hand washing involves wetting hands, applying soap, lathering and scrubbing for 20 seconds, rinsing, and drying thoroughly. Scrubbing is the most important step for removing germs and bacteria. When soap and water are unavailable, hand sanitizers can be an acceptable alternative if the sanitizer is rubbed thoroughly over all hand surfaces until dry. Proper hand washing is the most effective way to prevent the spread of communicable diseases.
