“…Cases of pneumonia with negative PCR test result, but with clinical and epidemiological signs, from August 1, 2020, began to be counted as a coronavirus infection (the virus was not identified). A decision was made to include this disease in the general statistics, as well as to carry out appropriate anti-epidemic measures, the same as during the registration of coronavirus infection (the virus was identified) [3], [4], [5]. The aim of the study was to analyze the epidemiological situation for coronavirus infection and pneumonia with signs of coronavirus infection in the republic.…”

New coronavirus infection caused by SARS-CoV-2 (COVID-19), as well as pneumonia with signs of coronavirus infection, continues to spread around the world, but the epidemiological situation is not the same in different countries. The aim of the study: to analyze the epidemiological situation of coronavirus infection and pneumonia with signs of coronavirus infection in the Republic of Kazakhstan. Material and methods of the research: retrospective epidemiological analysis of the incidence of coronavirus infection and pneumonia with signs of coronavirus infection in the republic according to official statistical reporting, as well as a statistical analysis of discharge records of patients diagnosed with coronavirus infection (no virus identified) in a small town of Karaganda region was carried out. Results: An increase in cases, sick persons, recovered persons and lethal cases in population with positive PCR for COVID-19, as well as pneumonia with signs of coronavirus infection in the Republic of Kazakhstan was registered for the period from 08/01/2020 to 12/31/2021. The number of cases of coronavirus increased in 10.93 time, those who recovered – in 15.78 times, deaths – in 16.4 time, respectively. The increase in the number of cases of pneumonia with signs of coronavirus infection also increased in 16.24 time, the number of those who recovered at the beginning of the observation was not established, by the end the number of recovered was 76,989 people, the number of deaths increased in 173.83 time. Conclusion: An analysis of the discharge records of patients with pneumonia with signs of coronavirus infection revealed that 54.2% of the patients were females and 45.8% were males. The disease was registered in 21.8% of patients older than 60 years in the presence of concomitant diseases. Concomitant diseases were represented in 42% by arterial hypertension, in 26% by ischemic heart disease, in 14% by pyelonephritis. The same percentage of cases (12%) were chronic obstructive pulmonary disease and iron deficiency anemia, 11%

Education is one of the industries significantly affected by the novel coronavirus infection (COVID-19) pandemic. Whole countries and cities were isolated, public and private institutions ceased their activities, and the country's higher educational institutions were forced to stop full-time education and switch to distance learning. Thus, the purpose of this study was to compare the indicators of the mental state (depression, anxiety) of students during full-time and distance learning. The first study was carried out by us during the full-time study period (February 10-17, 2020, sample size n = 154), and the second study was conducted during the distance learning period (October 19-26, 2020, sample size n = 154). The study evaluated such indicators as satisfaction with academic performance, the severity of depressive symptoms and anxiety. The results obtained indicate that the prevalence of depressive symptoms and anxiety among students was significantly higher during the distance learning period compared to similar indicators obtained during the full-time study period. The results of this study indicate that a sudden shift from one learning regime to another was a causative factor in stressful stress, which led to a high prevalence of depressive symptoms and anxiety among undergraduate students.

Relevance. COVID-19 is an extremely dangerous disease that not only spreads quickly, but is also characterized by a high mortality rate. Therefore, prediction of the number of deaths from the new coronavirus is an urgent task. Research objective. The aim of the study is to provide a more accurate estimate of the real number of coronavirus-related deaths in Russian regions. Data and methods. The main research method is econometric modeling. Comparison of various data was also applied. The authors’ calculations were based on Rosstat data, the data of the World Bank and specialized sites with coronavirus statistics in Russia and in the world. Results. We identified the factors affecting the COVID-19 mortality rates in various countries were identified, assessed how much the official Russian statistics underestimated mortality in Russian regions, and provided predictive estimates of mortality as a result of the pandemic. We also determined the number of additional coronavirus-induced deaths. Conclusions. The official data on COVID-19 mortality in Russia underestimate the actual numbers more than twofold. The number of direct and indirect victims of the pandemic in Russia at the end of July was approximately 43 thousand people.
