【流星雨说明】病毒在进化， 世界各国的疫情此起彼伏， 想要找出一个客观的评估各国的疫情严重程度很难，评估的方法也在不断改进。
 各个网站最普遍使用的是各国的单日的确诊人数和病亡人数比较。流星雨发现有一些国家不是每天上报疫情数据，就进化成3日， 5日的确诊人数和病亡人数的平均值比较。流星雨其后又发现很多国家的数据周末统计不上来， 就改用了7日的平均值比较， 这个分析数据能够给出绝对人数上比较客观的疫情状况。
 由于各国的测试标准不同， 用上述的方法来比较各国的疫情惨烈程度实际上是不公平的。所有本篇分析， 使用了新的每百万国民的最近7日新冠病亡人数比较来横向衡量各国的疫情程度， 应该是目前最客观的比较方式。
疫情的数据， 取自世界卫生组织和美国霍普金斯大学的世界疫情数据库， 同步到发帖前的几分钟。
世界各国的人口数据， 取自世界银行组织， 更新到2018年， 人口在三年内的差异对本文的算法产生的误差， 可以忽略不计。
7日内新增的每百万国民新冠病亡人数
 
这是目前能反映一个国家疫情严重程度， 或者能比较国家之间疫情的严重程度的最客观的方法。

由于各国的检测标准不同， 同一个国家在不同时期的检测标准也不同， 用这个参数衡量一个国家的疫情严重程度没有用病亡的参数准确， 列在这里作为参考。
