(1) Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began spreading across the globe in December and, as of 9 July 2020, had inflicted more than 550,000 deaths. Public health measures implemented to control the outbreak caused socio-economic havoc in many countries. The pandemic highlighted the quality of health care systems, responses of policymakers in harmony with the population, and socio-economic resilience factors. We suggest that different national strategies had an impact on mortality and case count. (2) Methods: We collected fatality data for 17 countries until 2 June 2020 from public data and associated these with implemented containment measures. (3) Results: The outcomes present the effectiveness of control mechanisms in mitigating the virus for selected countries and the UAE as a special case. Pre-existing conditions defined the needed public health strategies and fatality numbers. Other pre-existing conditions, such as temperature, humidity, median age, and low serum 25-hydroxyvitamin D (25(OH)D) concentrations played minor roles and may have had no direct impact on fatality rates. (4) Conclusions: Prevention, fast containment, adequate public health strategies, and importance of indoor environments were determining factors in mitigating the pandemic. Development of public health strategies adapted to pre-existing conditions for each country and community compliance with implemented policies ensure the successful control of pandemics.

COVID-19 幕后花絮：国家感染控制战略及其对死亡率的影响。

(1) 背景：严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 于 12 月开始在全球传播，截至 2020 年 7 月 9 日，已造成超过 55 万人死亡。为控制疫情而采取的公共卫生措施在许多国家造成了社会经济破坏。此次疫情凸显了医疗保健系统的质量、政策制定者与民众协调一致的应对措施以及社会经济复原力因素。我们认为不同的国家战略对死亡率和病例数有影响。(2) 方法：我们从公共数据中收集了截至 2020 年 6 月 2 日 17 个国家的死亡数据，并将这些数据与已实施的遏制措施相关联。(3) 结果：结果显示了选定国家和阿联酋作为特例的控制机制在减轻病毒方面的有效性。原有疾病确定了所需的公共卫生策略和死亡人数。其他预先存在的条件，如温度、湿度、中位年龄和低血清 25-羟基维生素 D (25(OH)D) 浓度，影响较小，可能对死亡率没有直接影响。(4) 结论：预防、快速遏制、适当的公共卫生策略以及室内环境的重要性是缓解疫情的决定性因素。制定适合每个国家和社区现有条件的公共卫生战略，遵守已实施的政策，确保成功控制流行病。
