Hand-to-Face Contact of Preschoolers during Indoor Activities in Childcare Facilities in the Republic of Korea.

PURPOSE: This study aimed to characterize hand-to-face contact (HFC) in children and analyze the factors that affect HFC behaviors of preschoolers in childcare facilities in Korea. METHODS: Thirty preschoolers aged between 13 and 84 months were enrolled with parents' voluntary participation. Videotaping (10 children/childcare center/2 h) and video reading was performed from 23 November 2018 to 7 January 2019. RESULTS: A total of 2719 cases of HFC were observed in 30 participants within 2 h. The average contact with the facial mucosa (frequency/person/2 h) was 55.6 ± 42.2, of which the mouth (25.4 ± 23.9), the nose (20.4 ± 24.5), and the eye (9.8 ± 11.7) were the most frequent contacts, in that order. The average contact duration (sec/person/2 h) with the facial mucosa was 232.6 ± 169.7, of which the mouth (145.2 ± 150), the nose (57.6 ± 62.2), and the eyes (29.7 ± 42.3) were the longest in that order. The density distribution of the frequency and duration of mucosal contact was wider in boys than in girls. The mucosal and non-mucosal contact frequencies were significantly higher in boys (p = 0.027 and p = 0.030, respectively). CONCLUSION: Children's HFC frequency and duration were highest for the mouth, nose, and eyes. Boys tended to have a higher contact frequency than girls for both mucous and non-mucous HFC.

A pilot study investigating the social contact patterns of Korean elderly.

OBJECTIVES: This pilot study describes the characteristics of social contact patterns of the elderly, a group at high-risk for contracting infections. DESIGN: A cross-sectional design was used. SAMPLE: Participants included 30 volunteers aged 65 years or older. MEASUREMENTS: Records of a contact diary were maintained for a period of 24-hr. RESULTS: Thirty participants recorded 340 contacts within the 24 hr period, with a mean of 11.3 people daily. Physical encounters accounted for 50.9% of contacts. Participants with an occupation had significantly higher contacts than those without (p=.013). Contact type differed by location and duration (p<.001). Contact locations included: home (11.5%), work (2.4%), elderly welfare facilities (32.9%), transport (1.2%), and other places (52.1%). Contact duration (p < .001) and frequency (p < .001) differed by location. Contact duration differed by frequency (p < .001). CONCLUSIONS: The elderly participate in frequent physical contact that increases their risk of infection, especially among those with an occupation in comparison to those without an occupation. Infection control nursing should focus on providing education to reduce the risk of infections during contact events. Social distancing should be applied to limited periods of infection transmission risk.
