An observational study of hand-to-face contact via videotaping of Korean older people in daily life settings.

HFC was highest at the nose in Korean older people, followed by the mouth. Consequently, education about avoiding HFC of the nose and hygienic care of the nose should be a nursing priority. Awareness of the risks of HFC and the prophylactic effects of vigorous hand hygiene should be strengthened among the elderly to prevent the spread of infectious diseases via hand contact.
