Question

At what concentration is soap and hand sanitizer effective in combating the corona virus

Answer 1

CDC recommends using ABHR with 60-95% alcohol in healthcare settings. Unless hands are visibly soiled, an alcohol-based hand rub is preferred over soap and water in most clinical situations due to evidence of better compliance compared to soap and water. Hand rubs are generally less irritating to hands and are effective in the absence of a sink. [3]

Hands should be washed with soap and water for at least 20 seconds when visibly soiled, before eating, and after using the restroom
