Авторами проведен сравнительный анализ результатов клинико-эпидемиологического обследования 361 больных COVID-19  в двух группах сравнения: среднетяжелой (n=285) и тяжелой (n=76) формами заболевания, находившихся на стационарном лечении в федеральном госпитале на базе Самарского государственного медицинского университета в 2020 году. Диагноз был верифицирован методом иммуноферментного анализа (ИФА) и/или полимеразной цепной реакции (ПЦР).</p></sec><sec><title>Результаты</title><p>Результаты. По гендерным и возрастным характеристикам больных COVID-19 значимых различий в группах сравнения не выявлено. Можно отметить на уровне тенденции (р=0,008) несколько более старший возраст пациентов второй группы 62,5 (53,0–68,8) относительно пациентов в первой 57,0 (47,0–65,0). У больных COVID-19 в зависимости от  степени тяжести заболевания различались сроки госпитализации: чем дольше пациенты оставались дома, тем более вероятным становилось тяжелое течение болезни. Клинические признаки, свидетельствующие о более благоприятном течении: − боль в горле, насморк; о серьезном прогнозе заболевания свидетельствуют: одышка, любые изменения сознания, тошнота, нарушение стула на 2-3 неделе заболевания.  В группе пациентов с тяжелым течением COVID-19 удельный вес больных с наличием сопутствующих заболеваний (особенно, более чем одной системы) был выше (74% и 63% соответственно).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to analyze clinical and epidemiological characteristics of patients with COVID-19 treated in a federal hospital of Samara region and their association with disease severity. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. We analyzed the results of clinical and epidemiological examination of 361 patients with  COVID-19 divided into two groups: patients with moderate disease (n = 285) and patients with severe disease (n  = 76). All study participants received inpatient treatment in the federal hospital of Samara State Medical University  in 2020. The diagnosis was verified using enzyme-linked immunosorbent assay (ELISA) and/or  polymerase chain reaction (PCR).</p></sec><sec><title>Results</title><p>Results. There were no significant differences in the gender and age of COVID-19 patients in the two groups compared. Patients in Group 2 were slightly older than those in Group 1 (62.5 years (range: 53.0–68.8) vs 57.0 years (47.0–65.0) (trend; р = 0.008). The disease severity correlated with the time to hospitalization: the longer patients stayed at home, the more likely they developed severe disease. Such symptoms as sore throat and rhinorrhea were associated with a less severe disease, whereas shortness of breath, any changes in consciousness, nausea, and stool disorders on weeks 2–3 of the disease correlated with a more severe course. The proportion of patients with concomitant diseases (especially, more than one) was significantly higher in patients  with severe COVID-19 than in patients with moderate COVID-19 (74% vs 63%). </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>клиника</kwd><kwd>эпидемиология</kwd><kwd>Самарская область</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>clinical manifestations</kwd><kwd>epidemiology</kwd><kwd>Samara region</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">ФГБОУ ВО Самарский государственный медицинский университет МЗ РФ,  г.
