What is the role of hand sanitizer in infection control?

Hand sanitizer plays a crucial role in infection control, especially in situations where soap and water are not accessible. The primary utility of hand sanitizer lies in its ability to significantly reduce the number of germs on the hands when thorough handwashing is not an option. It is particularly useful in settings like healthcare facilities or public spaces, where hand hygiene is essential for preventing the transmission of infections.

Hand sanitizers, particularly those containing at least 60% alcohol, are effective against many types of bacteria and viruses, making them a viable alternative to traditional handwashing when necessary. However, they are not as effective as soap and water for removing certain types of germs, like those that may be present from bodily fluids or if hands are visibly soiled. Therefore, it is recommended to use hand sanitizer in conjunction with regular handwashing practices whenever possible rather than as a complete substitute.

Understanding this role is critical for effective infection control in various environments, from healthcare settings to everyday community practices.
