论文摘要
多项研究表明，COVID-19的传播受气候，BCG疫苗接种，污染和血型等因素的影响。我们使用机器学习和贝叶斯方法的全球40个地区的死亡增长率进行了联合研究。我们发现弱，无显着的（<3 $σ$）的温度和相对湿度证据是COVID-19的传播的因素，但几乎没有或没有BCG疫苗接种率或$ \ Text {PM} _ {2.5} $污染的证据。在统计学上显着的水平（> 3 $σ$）上检测到的唯一变量是阳性COVID-19测试的速率，其正率较高，与较高的每日死亡增长相关。
Multiple studies have suggested the spread of COVID-19 is affected by factors such as climate, BCG vaccinations, pollution and blood type. We perform a joint study of these factors using the death growth rates of 40 regions worldwide with both machine learning and Bayesian methods. We find weak, non-significant (< 3$σ$) evidence for temperature and relative humidity as factors in the spread of COVID-19 but little or no evidence for BCG vaccination prevalence or $\text{PM}_{2.5}$ pollution. The only variable detected at a statistically significant level (>3$σ$) is the rate of positive COVID-19 tests, with higher positive rates correlating with higher daily growth of deaths.
