In this analysis, we observed that human development index (an integrated index of life expectation, education and living standard) correlates with infection rate (proportion of confirmed cases among the population) and the fatality rate of COVID-19 in Italy based on data as of May 15, 2020. Further analysis showed that HDI is negatively correlated with cigarette consumption, whereas it is positively correlated with chronic disease and average annual gross salary. These factors may partially explain why unexpected positive correlation is observed between human development index and risk of infections and deaths of COVID-19 in Italy.
在本分析中，基于截至2020年5月15日的数据，我们观察到人类发展指数（预期寿命、教育和生活水平的综合指数）与意大利新冠肺炎的感染率（确诊病例在人口中的比例）和死亡率相关。进一步分析表明，人类发展指数与香烟消费量呈负相关，而与慢性病和平均年薪呈正相关。这些因素可能部分解释了为何在意大利人类发展指数与新冠肺炎的感染和死亡风险之间观察到意外的正相关。
