What is the primary purpose of hand sanitizer in infection control?

The primary purpose of hand sanitizer in infection control is to reduce the number of germs when soap and water are unavailable. Hand sanitizers are designed to kill a significant amount of germs (including bacteria and some viruses) quickly and effectively, making them a valuable tool for infection prevention in various settings, particularly in healthcare. They provide a convenient alternative when handwashing facilities are not accessible, helping to maintain hygiene and limit the spread of infections.

While some may wonder about the moisturizing properties of hand sanitizers or their potential use on surfaces, these points do not reflect the main function they serve in infection control. Hand sanitizers cannot replace the thorough cleaning provided by soap and water, especially after certain activities like using the restroom or when hands are visibly dirty. It’s essential for healthcare workers to understand that hand hygiene is foundational in preventing healthcare-associated infections, and hand sanitizers play a crucial role when soap and water cannot be used.
