The purpose of the article is to study the statistical material and to search for patterns and relationships of indicators, which will help us understand the global trend of fight against the COVID-19. Gradual reduction of the number of critical cases is proven due to the development of new methods and implementation of strategies to defeat COVID-19 worldwide. The analysis clearly shows structure and correlation between the number of recovered patients and total COVID-19 patients in relative terms to the number of all infected by COVID-19 in the world, and this relationship is shown to be close and inverted. The cyclical nature of the behavior of such interconnections is proved, which testifies both to the natural and objective regularity. The proposed study results will help medics and government in all countries to better cope with the problem and prepare in advance for the outbreak of disease.encritical casesnumber of patientsnumber of recovered patientsnumber of infectedcorrelation coefficientapproximationcycleArticle
