Logistic regression was applied to a cohort of 80 theater attendees to identify risk factors for infection. The infection source and transmission route were determined through gene sequencing data analysis.Results: Of the 48 confirmed cases, 35 were theater attendees (72.9%), 10 were family members of attendees (20.8%), 2 were friends (4.2%), and 1 was an employee (2.1%). Among the 80 individuals who attended the 3rd to 5th screenings of the day, 35 became infected, representing a 45.0% attack rate. Specifically, 28 of the 33 third-screening attendees developed confirmed SARS-CoV-2, constituting an 84.8% attack rate. Furthermore, 11 of the 12 cases epidemiologically linked to the theater outbreak were clustered monophyletically within the AY.69 lineage. At the time of the screening, 35 individuals (72.9%) had received 2 vaccine doses. However, vaccination status did not significantly influence infection risk. Multivariate analysis revealed that close contacts had a 15.9-fold higher risk of infection (95% confidence interval, 4.37\u201378.39) than casual contacts.Conclusion: SARS-CoV-2 transmission occurred within the theater, and extended into the community, via a moviegoer who attended the 3rd screening during the viral incubation period after contracting the virus from a family member. This study emphasizes the importance of adequate ventilation in theaters.<\/jats:p>","DOI":"10.24171\/j.phrp.2023.0269","type":"journal-article","created":{"date-parts":[[2024,1,31]],"date-time":"2024-01-31T00:08:06Z","timestamp":1706659686000},"page":"45-55","update-policy":"https:\/\/doi.org\/10.24171\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Risk factors for SARS-CoV-2 transmission during a movie theater outbreak in Incheon in the Republic of Korea, November 2021: a retrospective study"],"prefix":"10.24171","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5367-4637","authenticated-orcid":true,"given":"Hye Young","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5971-7829","authenticated-orcid":true,"given":"Young-Joon","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2114-579X","authenticated-orcid":true,"given":"Sang-Eun","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6435-935X","authenticated-orcid":true,"given":"Han-Na","family":"Yoo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3566-5523","authenticated-orcid":true,"given":"Il-Hwan","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4400-7872","authenticated-orcid":true,"given":"Jin Sun","family":"No","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6784-8004","authenticated-orcid":true,"given":"Eun-Jin","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4619-5598","authenticated-orcid":true,"given":"Jungyeon","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0353-3489","authenticated-orcid":true,"given":"Sanghwan","family":"Bae","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5831-1053","authenticated-orcid":true,"given":"Mi","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"31909","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1126\/science.abf0521"},{"key":"ref2","volume-title":"Transmission of SARS-CoV-2: implications for infection prevention precautions: scientific brief, 09 July 2020 [Internet]","author":"World Health Organiz","year":"2023"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s10389-020-01321-z"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1377\/hlthaff.2020.00608"},{"key":"ref5","volume-title":"Social distancing could buy U.S. valuable time against coronavirus.
