Analyze a set of indicators to understand the variability of the evolution and impact of the COVID-19 epidemic in a set of selected countries.
Ecological study of a group of countries with more than 200 reported cases. Demographic variables, health expenditure variables, and variables about characteristics of health services were included as explanatory variables. and incidence, mortality and fatality rates have been analyzed as response variables. In addition, a relative fatality index has been created. Data are from international organizations. Spearman's correlation coefficient was used to estimate the magnitude of the associations.
Number of tests and of medical professionals are associated with a higher incidence rate. Mortality and case fatality rate are not associated with demographic, health expenditure, or health services variables.
Differences suggest a general underestimation of the magnitude of the epidemic. Improvement of case identification and effectiveness of epidemiological surveillance systems is necessary.
分析一组指标，以了解新冠疫情在一组选定国家中的演变情况及影响的变异性。
对一组报告病例超过200例的国家进行生态研究。将人口统计学变量、卫生支出变量以及卫生服务特征变量作为解释变量。将发病率、死亡率和病死率作为反应变量进行分析。此外，还创建了一个相对病死率指数。数据来自国际组织。使用斯皮尔曼相关系数来估计关联的程度。
检测次数和医疗专业人员数量与较高的发病率相关。死亡率和病死率与人口统计学、卫生支出或卫生服务变量无关。
差异表明疫情规模普遍被低估。有必要改进病例识别和流行病学监测系统的有效性。
