A touchless and privacy-conscious check-in procedure for visitor assessment is critical to safeguarding venues against potential virus transmission.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In our study, we developed an interaction-free entry system featuring anonymous visitors who voluntarily provide data. This system introduces an adaptable venue entry management mechanism that accounts for both visitors' potential risk and the venue's capacity, aiming to curb the risk of localized infections. We assess visitors' liability based on their voluntarily provided data through radar map analysis. Additionally, we evaluate the venue's situation by quantifying its risk from multiple dimensions. A queuing model is then employed to control visitor access adaptively based on visitors' liability and the venue's availability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Since May, our university campus has been the operational site for the implemented system, catering to the needs of visitors across distinct venues. Using real-world implementation, we conduct a series of simulation experiments and case studies to verify the effectiveness of the HealthPass system in lowering infection risks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>The system has demonstrated its capacity to reduce infection risks by adapting visitor entry procedures based on individual risk factors and venue conditions. Our results suggest that the integration of a dynamic queuing model and real-time data analysis can effectively manage the flow of visitors while ensuring public health safety.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2024.1448901","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T06:23:59Z","timestamp":1733984639000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["HealthPass: a contactless check-in and adaptive access control system for lowering cluster infection risk in public health crisis"],"prefix":"10.3389","volume":"12","author":[{"given":"Guofeng","family":"Luo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yufei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linghong","family":"Hong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiaru","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qu","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Longbiao","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,12,12]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"764","DOI":"10.1016\/S0140-6736(20)30421-9","article-title":"COVID-19 control in China during mass population movements at New Year","volume":"395","author":"Chen","year":"2020","journal-title":"Lancet"},{"key":"B2","first-page":"E077","article-title":"Inference of start time of resurgent COVID-19 epidemic in Beijing with SEIR dynamics model and evaluation of control measure effect","volume":"41","author":"Wei","year":"2020","journal-title":"Zhonghua liu Xing Bing xue za zhi= Zhonghua Liuxingbingxue Zazhi"},{"key":"B3","doi-asserted-by":"publisher","first-page":"860","DOI":"10.1126\/science.abb5793","article-title":"Projecting the transmission dynamics of SARS-CoV-2 through the postpandemic period","volume":"368","author":"Kissler","year":"2020","journal-title":"Science"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1145","DOI":"10.1007\/s11845-020-02215-5","article-title":"Application of personal-oriented digital technology in preventing transmission of COVID-19, China","volume":"189","author":"Pan","year":"2020","journal-title":"Irish J Med Sci"},{"key":"B5","doi-asserted-by":"publisher","first-page":"1341","DOI":"10.1001\/jama.2020.3151","article-title":"Response to COVID-19 in Taiwan: big data analytics, new technology, and proactive testing","volume":"323","author":"Wang","year":"2020","journal-title":"JAMA"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1101\/2020.04.17.20069211","article-title":"A web-based, mobile responsive application to screen healthcare workers for COVID symptoms: descriptive study","author":"Zhang","year":"2020","journal-title":"medRxiv"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.48550\/arXiv.2005.07038","article-title":"Crowd control in plazas constrained to social distancing","author":"Garc\u00eda","year":"2020","journal-title":"arXiv"},{"key":"B8","doi-asserted-by":"publisher","first-page":"1362","DOI":"10.1126\/science.abc0473","article-title":"Rapid implementation of mobile technology for real-time epidemiology of COVID-19","volume":"368","author":"Drew","year":"2020","journal-title":"Science"},{"key":"B9","doi-asserted-by":"publisher","first-page":"523","DOI":"10.1215\/18752160-8698301","article-title":"Tracetogether: pandemic response, democracy, and technology","volume":"14","author":"Stevens","year":"2020","journal-title":"East Asian Sci Technol.
