Background: This study aimed to characterize sources of knowledge on the means of prevention of SARS-CoV-2 infections as well as to assess the methods of preventing SARS-CoV-2 infection among police employees in Poland and their potential impact on the risk of SARS-CoV-2 infection. Methods: The study consisted of two phases: questionnaire and laboratory tests for SARS-CoV-2 infection. The questionnaire included 30 questions related to risk factors, knowledge about SARS-CoV-2, and methods of infection prevention. Results: Data were obtained from 5082 police employees. The most common source of knowledge for a daily update on SARS-CoV-2 infection prevention was the Internet (42.6%), television (40.3%), and radio (39.7%). The most commonly used methods of SARS-CoV-2 infection included washing one’s hands for at least 20 seconds (95.8%), wearing facemasks (82.9%), and physical distancing (74.9%). Results of IgG tests were lower in police units where the overall compliance with the preventive measures was higher (p < 0.01). Women were more likely to exercise SARS-CoV-2 infection prevention behaviors compared to men. Compliance with the recommended protective measures increased with age. Conclusions: Lower anti-SARS-CoV-2 IgG seropositivity rates were observed in police units with better overall compliance with the preventive measures, suggesting the key importance of group rather than individual behaviors.

波兰警察中预防 SARS-CoV-2 感染——对公共卫生政策的影响

背景：本研究旨在描述预防 SARS-CoV-2 感染手段的知识来源，并评估波兰警察雇员预防 SARS-CoV-2 感染的方法及其对感染风险的潜在影响。 SARS-CoV-2 感染。方法：该研究分为两个阶段：针对 SARS-CoV-2 感染的问卷调查和实验室检测。调查问卷包括 30 个问题，涉及危险因素、SARS-CoV-2 知识和感染预防方法。结果：数据来自 5082 名警察雇员。每日更新 SARS-CoV-2 感染预防知识的最常见来源是互联网（42.6%）、电视（40.3%）和广播（39.7%）。最常用的 SARS-CoV-2 感染方法包括洗手至少 20 秒（95.8%）、戴口罩（82.9%）和保持身体距离（74.9%）。警察单位的 IgG 检测结果较低，预防措施的总体依从性较高 ( p < 0.01)。与男性相比，女性更有可能采取 SARS-CoV-2 感染预防行为。随着年龄的增长，对建议的保护措施的遵守程度也会提高。结论：在总体上遵守预防措施较好的警察单位中，抗 SARS-CoV-2 IgG 血清阳性率较低，这表明群体行为比个人行为更重要。
