Ростовская область вошла в число десяти наиболее пораженных регионов России. Распространение болезни во многом определяется состоянием популяционного иммунитета на определенной территории.</p><p>Целью настоящего исследования являлись изучение специфического гуморального иммунного ответа и оценка уровня популяционного иммунитета к вирусу SARS-CoV-2 среди населения Ростовской области.</p><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании приняли участие 3048 человек. Волонтеры распределялись по семи возрастным группам. Содержание антител к SARS-CoV-2 определяли методом ИФА с использованием набора для анализа сыворотки или плазмы крови человека на наличие специфических IgG к нуклеокапсиду вируса SARS-CoV-2 производства Государственного научного центра прикладной микробиологии и биотехнологии (Оболенск) в соответствии с инструкцией по применению.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Проведенная оценка серопревалентности к SARS-CoV-2 жителей Ростовской области показала, что доля лиц с положительными результатами теста на антитела IgG к новому коронавирусу составила 16,5 %, доля серопозитивных лиц в генеральной совокупности находится в пределах от 13,9 до 19,1 % (р&lt;0,05). Достоверных гендерных различий в уровне серопревалентности не установлено, положительный результат зарегистрирован у 16,6 % обследованных женщин и 16,5 % мужчин. Установлен высокий уровень гуморального иммунитета к SARS-CoV-2 на фоне низких показателей заболеваемости у лиц в возрасте от 1 года до 17 лет, что может свидетельствовать о доминировании бессимптомных форм болезни среди данной возрастной группы. Наибольший уровень серопозитивности выявлен среди дошкольников (33,6 %), учащихся (29,3 %), служащих (17,3 %), работников образования (15,3 %). </p></sec></abstract><trans-abstract xml:lang="en"><p>By August 2020, more than 850000 cases of new coronavirus infection (COVID-19) caused by SARSCoV-2 were confirmed in the Russian Federation, with the Rostov Region as one of the ten most affected regions in Russia. The spread of the disease is largely determined by the state of population immunity in a certain area. Our research focuses on specific humoral immune response and estimates the level of herd immunity to SARS-CoV-2 virus among the population of the Rostov Region.</p><sec><title>Materials and methods</title><p>Materials and methods. The study involved 3,048 people; the volunteers participating in the study were divided into seven age groups. The content of antibodies to SARS-CoV-2 was determined applying ELISA using a kit for the analysis of human serum or blood plasma for the presence of specific IgG to the nucleocapsid of the SARS-CoV-2 virus, manufactured by the State Scientific Center of Applied Microbiology and Biotechnology (Obolensk) in accordance with the instructions for use.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The assessment of seroprevalence to SARS-CoV-2 in the Rostov Region showed that the proportion of people positive for IgG to the new coronavirus was 16.5 %, the range of seropositive individuals in the general population was between 13.9 % and 19.1 % (p&lt;0.05). There were no significant gender differences in the degree of seroprevalence with a positive result registered in 16.6 % of women and 16.5 % of men. A high level of humoral immunity to SARS-CoV-2 was established in individuals aged 1–17 against the background of low incidence rates, which may indicate the dominance of asymptomatic forms of the disease in this age group. The highest level of seropositivity was found in preschool children (33.6 %), students (29.3 %), employees (17.3 %), and education professionals (15.3 %). </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>популяционный иммунитет</kwd><kwd>антитела IgG</kwd><kwd>Ростовская область</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>population immunity</kwd><kwd>antibody IgG</kwd><kwd>Rostov Region</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tyrrell D.A., Bynoe M.L.
