Item Influence of Meteorological Factors on Covid-19 Incidence in the Conditions of Ukraine(Bangladesh Journal of Medical Science, 2023-04) Podavalenko, Alla; Malysh, Nina; Kuzmenko, Olga; Zadorozhna, Viktoriya; Kolomiets, Svitlana; Chemych, OksanaThe coronavirus disease (COVID-19) is a problem for the health care systems of many countries around the world. Seasonal nature of influenza and other the respiratory viral diseasesis commonly known. The nature of the relationship between the frequency of registration of cases of COVID-19 and natural factors is still being studied by researchers. The purpose is to determine the influence of air temperature, relative humidity, wind speed, and atmospheric pressure on the incidence of the coronavirus disease COVID-19 in the conditions of Ukraine.Item Analysis of the epidemic situation of the COVID-19 coronavirus infection in Ukraine(2023-04-30) Podavalenko, Alla; Malysh, Nina; Zadorozhna, Viktoriya; Zhuk, Kateryna; Zaitseva, Galina; Chorna, InnaThe epidemic process of COVID-19 in the world developed rapidly. The situation with mor bidity, 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 humidityPublication Conditions for the expansion of СOVID-19 in the regions of the Northern part of Ukraine Conditions for the expansion of СOVID-19 in Ukraine(2023-09-07) Korzh, Alexei; Georgiyants, Marine; Podavalenko, Alla; Nessonova, Tetyana; Maslova, Valentyna; Bereznyakov, Vladislav; Asoyan, IrinaBackground: The intensity of the COVID-19 epidemic process in the administrative territories of Ukraine differs. Risk factors for the spread of this infection have not been sufficiently studied, which prevents the development of adequate preventive and anti-epidemic measures at the local level. Objectives: Conduct an epidemiological analysis of the incidence of COVID-19 in the regions of the Northern part of Ukraine and identify the leading risk factors for spread. Material and Methods: The incidence of COVID-19 was analyzed for 73 weeks and 28 predictors. Fourier’s spectral analysis, Feature Selection and Variable Filtering method of the Data mining module, Irwin’s method, integral visual coefficient was used. Results. There were two rises in the incidence of COVID-19, the cyclicity was 18 - 24 weeks. The conditions for the spread of COVID-19 cases in the regions of the Northern part have been established, namely: the number of people and the elderly in the family, demographic and migration processes. Violation of regime-restrictive measures leads to abnormal rises in morbidity. Conclusions. The epidemic situation in the Northern part remains volatile, as there are conditions for the spread of COVID-19 that cannot be eliminated, as well as some, that need to be developed (tourism, demographic processes, financing, etc.). Therefore, compliance with restrictive measures and vaccination of the population of the region remain the main preventive measures.
