Background: Researchers across the world are emphasising the importance of hand-washing and limited touching of face to curb the spread of COVID-19. However, access to safe water and hygiene is inadequate in many places around the globe; hence T-zone touching restriction is considered more worthwhile compared to other prevention strategies. Aim: A systematic review was carried out to appraise the frequency of T-zone (eyes, nose, mouth, chin) touching in humans to comprehend the challenge of its restriction, and thus support public health professionals to produce evidence synthesis guidance for public. For this systemic review, data were collected by keyword searching, and several online databases were searched. The PRISMA checklist, PECO protocol and STROBE guideline were followed in this review, and pooled data were analysed in R version 4. Result: Total of 10 single arms observational studies were included. The pooled average (SD) facial self-touch per hour was 50.06 (±47) times, and a specific touch of T-zone was 68.7 (±27). T-zone self-touch within the total facial self-touch was found higher R = 0.680, with 95% CI 0.14, 0.91, P = 0.02 and X2 = 167.63, P < 0.0001. Conclusion: The review found that face-touch is a type of consistent regulatory movements. Control of T-zone touch requires extensive behaviour intervention and community awareness. |
