spread of infectious diseases.
As part of National Hand Washing Awareness Week, from Dec. 2 to Dec. 8, ElaineLarson, associate dean for research at Columbia University School of Nursing offersthe following guidelines for proper- hand washing techniques:
"The big mistake people make is that they just rub their palms together and they don't get the dirtiest parts of the hands" -- under and around the fingernails," said Larson. "It's necessary to cover all surfaces of the hands, between the fingers and in the crevices around fingernails, with a good amount of friction. Using soap is crucial because it acts as an emulsifier to slip the germs off the hands."
If you use a hand sanitizer, pick one that is at least 60% alcohol, and use enough so that your hands are wet for 10 seconds -- enough time to kill the bacteria, Larson said. "Alcohol sanitizers work only when they're wet, she said. But hand sanitizers can't kill all germs, such as the norovirus, a highly contagious stomach virus. Washing with lots of friction and then applying hand sanitizer can help against such resistantbugs."
