ANALYSIS OF THE RELATIONSHIP BETWEEN MORBIDITY, MORTALITY AND RESTRICTIVE MEASURES IN DIFFERENT COUNTRIES DURING THE COVID-19 PANDEMIC

Abstract

Introduction: The pandemic of the new coronavirus infection COVID-19 has posed the need for the healthcare system to promptly address the issues of organizing medical care for an increasing flow of patients. The scale of the pandemic has shown that no State has sufficiently demonstrated a high willingness to respond quickly and implement measures to reduce the outbreak of infection. The purpose of the study: To study morbidity and mortality in terms of the number of restrictive measures taken in different countries during the COVID-19 pandemic. Materials and methods: For the analysis, open sources of information from the Our World in Data portal were used, where world statistics on the COVID-19 pandemic were collected and systematized. The data analysis period is March 2020 to the present. The analysis includes countries such as the USA, Great Britain, Italy, Canada, India, China, Turkey, Israel, Russia and Kazakhstan. For the analysis, databases on the number of confirmed cases of the disease, the number of confirmed deaths and the severity index of restrictive measures were studied. A Spearman correlation analysis of the dependence of cases of diseases, deaths and Severity Index was carried out. Results and discussion: On March 11, 2020, the World Health Organization (WHO) announced the COVID-19 pandemic in the world. The incidence of coronavirus began to rise sharply, especially in European countries, despite the fact that there was not enough information about the virus, which caused panic among the world's population. In addition to the increase in morbidity, the level of mortality increased. Since 2020, restrictive measures have been introduced in many countries. It was difficult to assess the effectiveness of the implemented measures immediately. 2 years later, a Severity Index was developed, which took into account all the restrictive measures applied in the countries. The correlation analysis showed that the analysis of cases of disease and deaths for 04/18/2020 has a strong correlation r=0.732 (differences are statistically significant p=0.002), while the correlation of the Severity Index and deaths has a weak and statistically insignificant relationship (r=-0.067, p=0.814). The correlation analysis of the Severity Index and cases of the disease also have no correlation (r=0.036, p=0.899). Conclusions: An analysis of the relationship between morbidity, mortality and restrictive measures during the COVID-19 pandemic showed that there was no correlation between the restrictive measures taken during the pandemic and the level of diseases and mortality in the studied countries. There is a direct and strong correlation between the level of diseases and deaths in 2020 and 2022.
