Indirect contact infection is caused by pathogens transmitted to the mucosa from hands. Contact infection risk is influenced by the contamination of hands and environmental surfaces and increases with increased frequency of face touching. There are large variations among the results of studies investigating hourly face touching. We conducted a video monitoring survey to investigate face-touching frequency in a classroom and on an experimentally simulated train. The locations of observed face touching were classified as mucosa and non-mucosa on the face. The results of the present and previous studies showed that participants touched the non-mucosa and mucosa at a ratio of 56.3% and 43.7%, respectively, with a coefficient of variance around 0.12. We also observed a positive correlation between the frequency of contact with the mouth and the nose in our experiment, indicating that people who frequently touch their mouth also tend to frequently touch their nose.
