Universal behavior of the Covid-19 tails: Inverse power-law distribution

TL;DR

This paper demonstrates that the mortality distribution tails of Covid-19 follow a universal inverse power-law decay across different countries and over time, revealing a fundamental pattern in pandemic behavior.

Contribution

It is the first to identify and report the universal inverse power-law decay in Covid-19 mortality tails across multiple regions and time periods.

Findings

Covid-19 mortality tails follow inverse power-law distribution.

The decay pattern persists over time.

Universal behavior observed across countries and continents.

Abstract

Power-law distribution is one of the most important laws known in nature. Such a special universal behavior is known to occur in very few physical systems. In this Letter, we analyzed the mortality distribution of the Covid-19 pandemic tails for different countries and continents to discuss the possible universal behavior of the pandemic. Surprisingly, we found that the mortality distribution of Covid-19 final i.e., the latest tails in 2023 follows inverse power-law decays. These universal behaviors for the pandemic are reported in the present work for the first time. Additionally, we showed that these mortality tails also decay with time obeying to the inverse power-law.
