This cross-sectional study endeavors to assess the COVID-19 infection rate among the primary HCWs in Jiangsu Province subsequent to the implementation of adjusted epidemic prevention and control strategies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From January 17 to February 2, 2023, an extensive survey was conducted among primary HCWs in Jiangsu Province, employing a self-designed questionnaire. Logistic regression analysis was utilized to identify the factors associated with COVID-19 infection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The overall infection rate among primary HCWs stood at 81.05%, with a 95% confidence interval (<jats:italic>CI<\/jats:italic>) of 80.61\u201381.48%. Among those afflicted, cough, fatigue, and fever emerged as the three most prevalent symptoms, each with an incidence rate exceeding 80%. In the context of multivariate logistic regression, an elevated risk of COVID-19 infection was observed in correlation with female gender (adjusted odds ratio [a<jats:italic>OR<\/jats:italic>]\u2009=\u20091.12, 95% CI: 1.04\u20131.21), possessing a bachelor\u2019s degree or higher (a<jats:italic>OR<\/jats:italic>\u2009=\u20091.32, 95% CI: 1.23\u20131.41), accumulating over 10\u2009years of work experience (a<jats:italic>OR<\/jats:italic>\u2009=\u20091.28, 95% CI: 1.11\u20131.47), holding a middle-level cadre position (a<jats:italic>OR<\/jats:italic>\u2009=\u20091.22, 95% CI: 1.11\u20131.35), assuming the role of a unit leader (a<jats:italic>OR<\/jats:italic>\u2009=\u20091.30, 95% CI: 1.11\u20131.54), and working in a fever clinic for 1 to 10\u2009days per month (a<jats:italic>OR<\/jats:italic>\u2009=\u20091.42, 95% CI: 1.29\u20131.57). Conversely, advanced age (a<jats:italic>OR<\/jats:italic>\u2009=\u20090.76, 95% CI: 0.70\u20130.82), being underweight (a<jats:italic>OR<\/jats:italic>\u2009=\u20090.78, 95% CI: 0.69\u20130.90), current smoking (a<jats:italic>OR<\/jats:italic>\u2009=\u20090.64, 95% CI: 0.57\u20130.71), receiving 4 doses of COVID-19 vaccine (a<jats:italic>OR<\/jats:italic>\u2009=\u20090.49, 95% CI: 0.37\u20130.66), and pregnancy or perinatal status (a<jats:italic>OR<\/jats:italic>\u2009=\u20090.85, 95% CI: 0.72\u20130.99) were associated with a diminished risk of infection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Following the implementation of adjusted policies, a substantial proportion of primary HCWs in Jiangsu province contracted COVID-19. Female gender and younger age emerged as risk factors for COVID-19 infection, while no discernible link was established between professions and COVID-19 susceptibility. The receipt of COVID-19 vaccines demonstrated efficacy in curtailing the infection rate, underscoring the significance of bolstering prevention knowledge and heightening self-protective awareness among primary HCWs.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2023.1297770","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T04:43:36Z","timestamp":1703220216000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Primary healthcare workers\u2019 COVID-19 infection status following implementation of adjusted epidemic prevention and control strategies: a cross-sectional study in Jiangsu, China"],"prefix":"10.3389","volume":"11","author":[{"given":"Beier","family":"Lu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rongji","family":"Ma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinshui","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongjie","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haijian","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hualing","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengcheng","family":"Miao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongkang","family":"Qian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Biyun","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ya","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingwei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,12,22]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"727","DOI":"10.1056\/NEJMoa2001017","article-title":"A novel coronavirus from patients with pneumonia in China, 2019","volume":"382","author":"Zhu","year":"2020","journal-title":"N Engl J Med"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"497","DOI":"10.1016\/S0140-6736(20)30183-5","article-title":"Clinical features of patients infected with 2019 novel coronavirus in Wuhan","volume":"395","author":"Huang","year":"2020","journal-title":"China"},{"year":"","key":"ref3"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1418","DOI":"10.1016\/S0140-6736(20)30917-X","article-title":"COVID-19: the case for health-care worker screening to prevent hospital transmission","volume":"395","author":"Black","year":"2020","journal-title":"Lancet"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"1401","DOI":"10.1016\/S1473-3099(20)30589-2","article-title":"Risk of COVID-19 in health-care workers in Denmark: an observational cohort study","volume":"20","author":"Iversen","year":"2020","journal-title":"Lancet Infect Dis"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"2109","DOI":"10.1093\/cid\/ciaa588","article-title":"Analysis of the infection status of healthcare Workers in Wuhan during the COVID-19 outbreak: a cross-sectional study","volume":"71","author":"Zheng","year":"2020","journal-title":"Clin Infect Dis"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"547","DOI":"10.1016\/S2213-2600(20)30228-9","article-title":"Evidence mounts on the disproportionate effect of COVID-19 on ethnic minorities","volume":"8","author":"Kirby","year":"2020","journal-title":"Lancet Respir Med"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"1364","DOI":"10.15585\/mmwr.mm6938a3","article-title":"Update: characteristics of health care personnel with COVID-19 -
