BACKGROUND
Cases of COVID-19 infection have increased sharply in Europe since August 2020, and the WHO recommend the use of respirators in situations where keeping distance is not possible. The purpose of this study was to evaluate the impact of the use of respirators on infection cases and viral deaths in European countries.
METHODS
COVID-19 cases and related deaths in 29 countries relative to population were searched through the WHO database on 15.10.2020. Recent 14-day cases in relation to the population were retrieved from the European Center for Disease Prevention and Control's website, covering the period from 1 to 14 October 2020. Information related to the use of respirators was retrieved from the IHME database of the University of Washington at time point, 1.6.2020.
RESULTS
The proportion of people using of respirators at 1.6.2020 correlate negatively to the reported cases of disease (Rs = -0.528) and to deaths (Rs = -0.553). No significant correlation was found for recent cases or mortality. Countries with at least 60% respirator use did not differ from other countries.
CONCLUSION
Long-term use of respirators appears to reduce disease incidence and death in the population.
背景
自 2020 年 8 月以来，欧洲的 COVID-19 感染病例急剧增加，世界卫生组织建议在无法保持距离的情况下使用呼吸器。本研究的目的是评估在欧洲国家使用呼吸器对感染病例和病毒死亡的影响。
方法
通过世界卫生组织数据库于 2020 年 10 月 15 日搜索了 29 个国家与人口相关的 COVID-19 病例和相关死亡人数。从欧洲疾病预防控制中心的网站上检索了最近 14 天与人口有关的病例，涵盖了 2020 年 10 月 1 日至 14 日的时间段。从华盛顿大学 IHME 数据库中检索了与使用呼吸器相关的信息，时间点为 2020 年 6 月 1 日。
结果
截至 2020 年 6 月 1 日，呼吸器使用率与报告的疾病病例（Rs = -0.528）和死亡病例（Rs = -0.553）呈负相关。最近的病例或死亡率与使用呼吸器之间没有发现显著相关性。呼吸器使用率至少为 60%的国家与其他国家没有区别。
结论
长期使用呼吸器似乎可以降低人群中的疾病发病率和死亡率。
