Alternative to hand washing
Hand sanitizer is a liquid or gel generally used to decrease infectious agents on the hands. They are available as liquids, gels, and foams. Formulations of alcohol-based versions are preferable to hand washing with soap and water in most situations in the healthcare setting. Generally, it is more effective at killing microorganisms than soap and water, with some exceptions such as norovirus and clostridium difficile. The general use of non-alcohol based versions has no recommendations. Outside the healthcare setting, hand washing with soap and water is generally preferred. Hand washing should still be carried out if contamination can be seen or following the use of the toilet.
