Abstract

Power-law distribution is one of the most important laws known in nature. Such a special universal behaviour is known to occur in very few physical systems. In this study, we analyse the mortality distribution of the Covid-19 pandemic tails for different countries and continents to discuss the possible universal behaviour of the pandemic. Surprisingly, we found that the mortality distribution of Covid-19 final, i.e., the latest tails in 2023 or 2024 follows inverse power-law decays. These universal behaviours for the pandemic are reported in the present work for the first time. Furthermore, we showed that these mortality tails also decay with time obeying the inverse power law.
