摘要

我们提出了一种机制来解释covid - 19世界总病例的近似线性增长以及美国和意大利观察到的(平均)每日新病例(和每日死亡人数)的缓慢线性下降。在我们的解释中，我们认为一个给定的人口(整个世界或一个国家)由许多子集群组成，这些子集群在封锁后基本上是独立发展的。这种相互作用是通过一个子集群中流行病的爆发时间是一个概率密度随时间缓慢变化的随机变量来建模的。这种解释独立于流行病在单个子群中演变的规律。

Linear behavior in Covid19 epidemic as an effect of lockdown.

We propose a mechanism explaining the approximately linear growth of Covid19 world total cases as well as the slow linear decrease of the daily new cases (and daily deaths) observed (in average) in USA and Italy. In our explanation, we regard a given population (the whole world or a single nation) as composed by many sub-clusters which, after lockdown, evolve essentially independently. The interaction is modeled by the fact that the outbreak time of the epidemic in a sub-cluster is a random variable with probability density slowly varying in time. The explanation is independent of the law according to which the epidemic evolves in the single sub cluster.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
