African countries have not had the high case and death rates from COVID-19 as was predicted early in the pandemic. It is not well understood what factors modulated the rate of COVID-19 cases and death on the continent.
We collated data from the World Bank data site, Our World in Data and Freedom House for African for 54 African countries who are members of the African Union. We used them as explanatory variables in two general linear model regression analyses. COVID cases and deaths per 100,000 obtained from WHO COVID-19 dashboard on August 12, 2021, as outcome variables in two prediction models.
GDP, percentage of population under 14 years of age, Maternal Mortality Ratio, number of international tourists visiting per year and public transportation closures were not significant in predicting COVID-19 cases. Higher percentage of unemployed adults in the population, lower percentage of the population over 25 years of age with secondary education, internal travel restrictions increased spread of COVID-19 while international travel restrictions were associated with lower COVID-19 cases per 100,000 population. Higher levels of democratization results in higher cases of COVID-19. Unemployment, education and democratization were still significant for COVID-19 death in the same direction as they were for COVID-19 cases. Number of tourism visitors per year was also associated with higher COVID-19 death rates but not with case rates.
In African countries, internal movement restrictions enacted to inhibit COVID-19, had the opposite effect and enabled COVID-19 spread. Low Education levels and high unemployment were associated with having higher death rates from COVID-19. More studies are needed to understand the impact of tourism on COVID-19 and other infectious diseases arising from other regions on African countries, in order to put in place adequate control protocols.
非洲国家的 COVID-19 发病率和死亡率并没有像疫情早期预测的那样高。目前还不清楚是什么因素调节了非洲大陆 COVID-19 病例和死亡的速度。
我们从世界银行数据网站、Our World in Data 和自由之家收集了非洲联盟 54 个非洲国家的数据。我们将这些数据作为两个一般线性模型回归分析的解释变量。使用 2021 年 8 月 12 日世界卫生组织 COVID-19 数据仪表盘上获得的每 10 万人 COVID 病例和死亡人数作为两个预测模型的结果变量。
国内生产总值、14 岁以下人口比例、孕产妇死亡率、每年国际游客人数和公共交通关闭在预测 COVID-19 病例方面没有显著意义。人口中失业成年人比例较高、25 岁以上受过中等教育的人口比例较低、国内旅行限制增加了 COVID-19 的传播,而国际旅行限制与每 10 万人口 COVID-19 病例数较低有关。更高水平的民主化导致更高的 COVID-19 病例数。在 COVID-19 死亡方面,失业、教育和民主化的方向仍然与 COVID-19 病例相同,仍然具有重要意义。每年的游客人数也与更高的 COVID-19 死亡率有关,但与病例率无关。
在非洲国家,为抑制 COVID-19 而颁布的国内流动限制措施产生了相反的效果,使 COVID-19 得以传播。教育水平低和高失业率与 COVID-19 死亡率较高有关。需要进一步研究旅游对 COVID-19 以及其他来自其他地区的传染病对非洲国家的影响,以便制定适当的控制方案。
