A common way to prevent the spread of germs is through proper hand hygiene, particularly handwashing. Using soap and water to wash hands is effective in removing dirt, viruses, and bacteria that can cause illness. The recommended technique involves scrubbing hands for at least 20 seconds, ensuring all parts, including between fingers and under nails, are cleansed. Hand sanitizer containing at least 60% alcohol can be used when soap and water are unavailable. Additionally, covering coughs and sneezes, avoiding close contact with sick individuals, and regularly disinfecting surfaces contributes to reducing germ transmission and maintaining overall public health.
