The threat of emerging and re-emerging infectious diseases exists as an imminent threat to human health. It is essential to implement adequate hygiene best practices to break the contagion chain and enhance society preparedness for such critical scenarios and understand the relevance of each disease transmission route. As the unconscious hand\u2013face contact gesture constitutes a potential pathway of contagion, in this paper, the authors present a prototype system based on low-cost depth sensors able to monitor in real-time the attitude towards such a habit. The system records people\u2019s behavior to enhance their awareness by providing real-time warnings, providing for statistical reports for designing proper hygiene solutions, and better understanding the role of such route of contagion. A preliminary validation study measured an overall accuracy of 91%. A Cohen\u2019s Kappa equal to 0.876 supports rejecting the hypothesis that such accuracy is accidental. Low-cost body tracking technologies can effectively support monitoring compliance with hygiene best practices and training people in real-time. By collecting data and analyzing them with respect to people categories and contagion statistics, it could be possible to understand the importance of this contagion pathway and identify for which people category such a behavioral attitude constitutes a significant risk.<\/jats:p>","DOI":"10.3390\/s20216149","type":"journal-article","created":{"date-parts":[[2020,10,29]],"date-time":"2020-10-29T21:21:00Z","timestamp":1604006460000},"page":"6149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Body Tracking-Based Low-Cost Solution for Monitoring Workers\u2019 Hygiene Best Practices during Pandemics"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5293-9955","authenticated-orcid":false,"given":"Vito M.","family":"Manghisi","sequence":"first","affiliation":[{"name":"Department of Mechanics, Mathematics, and Management, Polytechnic University of Bari, via Oraboba 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2197-6574","authenticated-orcid":false,"given":"Michele","family":"Fiorentino","sequence":"additional","affiliation":[{"name":"Department of Mechanics, Mathematics, and Management, Polytechnic University of Bari, via Oraboba 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9623-7189","authenticated-orcid":false,"given":"Antonio","family":"Boccaccio","sequence":"additional","affiliation":[{"name":"Department of Mechanics, Mathematics, and Management, Polytechnic University of Bari, via Oraboba 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4487-0457","authenticated-orcid":false,"given":"Michele","family":"Gattullo","sequence":"additional","affiliation":[{"name":"Department of Mechanics, Mathematics, and Management, Polytechnic University of Bari, via Oraboba 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1471-9799","authenticated-orcid":false,"given":"Giuseppe L.","family":"Cascella","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering and Information Technology, Polytechnic University of Bari, via Oraboba 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1929-5833","authenticated-orcid":false,"given":"Nicola","family":"Toschi","sequence":"additional","affiliation":[{"name":"Department of Biomedicine and Prevention, University of Rome \u2018Tor Vergata\u2019 Facolt\u00e0 di Medicina e Chirurgia Viale Montpellier, 1, 00133 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Pietroiusti","sequence":"additional","affiliation":[{"name":"Department of Biomedicine and Prevention, University of Rome \u2018Tor Vergata\u2019 Facolt\u00e0 di Medicina e Chirurgia Viale Montpellier, 1, 00133 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio E.","family":"Uva","sequence":"additional","affiliation":[{"name":"Department of Mechanics, Mathematics, and Management, Polytechnic University of Bari, via Oraboba 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,29]]},"reference":[{"key":"ref_1","unstructured":"WHO (2020, June 04).
