Analysis of the epidemic situation of the COVID-19 coronavirus infection in Ukraine.

The epidemic process of COVID-19 in the world developed rapidly. The situation with morbidity, despite the establishment of quarantine, the introduction of restrictive anti-epidemic measures, and vaccination, remains difficult. The results of research on the influence of meteorological factors on the dynamics of the incidence of COVID-19, hospitalization, and mortality are ambiguous and contradictory. The purpose of this study is to analyze the indicators of morbidity, hospitalization, and mortality from COVID-19 in Ukraine, and to establish the level of influence of meteorological factors on them. A high variation in morbidity, hospitalization, and mortality rates was observed in Ukraine, in 2020-2021. A total of 3 waves of disease growth were established. The curve of hospitalization indicators of patients with COVID-19 had a correlation dependence on the incidence curve r = 0.766 (р <0.05), the maximum rates of hospitalization and mortality were registered in September-December 2021. A direct strong correlation was established between the frequency of registration of cases of COVID-19 and mortality - r = 0.899 (р <0.05). Most cases of COVID-19 were registered in the cold season, the least in June-August. Inverse correlations of moderate strength were established between the indicators of morbidity, hospitalization, and mortality and air temperature levels (-0.370< r <-0.461). Direct correlations of average strength (0.538< r <0.632) were established with the levels of relative air humidity.

MEDICAL AND SOCIAL ANALYSIS OF PATIENTS WHO DIED OF SARS-COV-2 IN THE SPECIALIZED INFECTIOUS DEPARTMENT OF THE CITY OF SUMY DURING THE FIRST WAVE OF THE EPIDEMIC.

OBJECTIVE: The aim of the article is to analyze demographic indicators, clinical symptoms, concomitant pathology, and the course of acute respiratory viral infection (ARVI) caused by SARS-CoV-2 in patients with a fatal outcome of the disease. PATIENTS AND METHODS: Materials and methods: To achieve the goal, a statistical method, an analytical method, and a method of retrospective analysis of the medical histories of patients with fatal cases who were hospitalized with a diagnosis of ARVI caused by SARS-CoV-2 were used. RESULTS: Results: Mortality among patients who were hospitalized with a diagnosis of ARVI caused by SARS-CoV-2 was 8.18 ± 2.17%. Among them, 62% were male and 38% were female. Cardiovascular pathology took first place in the structure of concomitant pathology of all age groups and accounted for 76%. Oncological diseases accounted for 62%, gastrointestinal diseases - 54%, endocrine diseases - 38%, and respiratory system diseases 23% of the total number of patients with fatal cases. CONCLUSION: Conclusions: Mortality from coronavirus infection in the period March - July 2020 among the male population was 62%, of which 13% - from the age group 18-45 years, 38% - from the age group 46-64 years, and 50% - patients 65 years old and older. Among the female population, the mortality rate was 38%, of which 20% were women in the age group 46-64% and 80% were 65 years and older. The presence of no-hospital polysegmental pneumonia as a complication of ARVI caused by SARS-CoV-2 was 62% among all age groups of the studied patients with fatal cases.
