Covid-19 is a betacoronavirus that was initially transmitted to humans from an animal host. It enters the cell by binding its protein S with angiotensin-converted enzyme receptors. It is transmitted through direct contact and respiratory drops. The most affected population so far are older adults and people with chronic conditions. The objective of this research is to analyze the possible association between the structure of the population pyramid, the Gross Domestic Product, the type of isolation and screening used to detect Covid-19 in the countries with the highest and lowest mortality from this disease. Some variables take part in the Covid- 19 mortality worldwide, such as the population structure, expressed in the population pyramid by country, the type of isolation adopted in each nation, the Gross Domestic Product (GDP) as well as the type of screening that is implemented in the different countries analyzed. After analyzing the mean difference in the countries with a regressive and progressive population pyramid, an association was identified between the regressive population pyramid structure and the higher mortality rate (p<0.001). The countries with a progressive population pyramid are the most benefited by making their population more screened since the mortality rate decreases significantly compared to the countries with less attribution (p<0.036).
新冠病毒是一种β冠状病毒，最初从动物宿主传播给人类。它通过其蛋白质S与血管紧张素转换酶受体结合进入细胞。它通过直接接触和呼吸道飞沫传播。迄今为止，受影响最大的人群是老年人和患有慢性病的人。本研究的目的是分析在该疾病死亡率最高和最低的国家中，人口金字塔结构、国内生产总值、用于检测新冠病毒的隔离和筛查类型之间可能存在的关联。一些变量在全球新冠病毒死亡率中起作用，例如以各国人口金字塔表示的人口结构、每个国家采用的隔离类型、国内生产总值（GDP）以及在分析的不同国家实施的筛查类型。在分析了人口金字塔呈衰退型和增长型的国家之间的平均差异后，发现衰退型人口金字塔结构与较高死亡率之间存在关联（p<0.001）。人口金字塔呈增长型的国家通过对更多人口进行筛查而受益最大，因为与筛查力度较小的国家相比，其死亡率显著降低（p<0.036）。
