Which of the following is the primary purpose of using alcohol-based hand rub?

The primary purpose of using alcohol-based hand rub is to reduce pathogen transmission. Alcohol-based hand rubs are specifically formulated to kill a wide range of bacteria and viruses present on the skin, effectively lowering the microbial load. This makes them an essential part of infection control practices, especially in healthcare settings where the risk of hospital-acquired infections is significant.

While cleansing the hands from dirt is important for overall hygiene, alcohol-based hand rubs are not as effective for this purpose if hands are visibly soiled; soap and water are recommended in such cases. Moisturizing dry skin is not a primary function of alcohol-based hand rubs, even though some products may contain moisturizing agents. Removing allergens is not associated with hand hygiene practices; alcohol-based hand rubs primarily focus on antimicrobial efficacy rather than allergen removal. Thus, the effectiveness of alcohol-based hand rubs in reducing pathogen transmission is what makes them a crucial component of hand hygiene protocols.
