Ветряная оспа занимает ведущие позиции в структуре инфекционной патологии в Республике Беларусь, ежегодно в стране регистрируется 50 000-80 000 случаев, в том числе 2500-4500 случаев среди лиц старше 15 лет. Цель - изучить распространенность IgG антител к вирусу Varicella Zoster среди населения Республики Беларусь и оценить относительный риск инфицирования для лиц разного возраста. Материалы и методы. Исследованы сыворотки крови 1190 человек в возрасте 2-75 лет, жителей всех 7 регионов Республики Беларусь. Антитела IgG определяли с использованием иммуноферментной тест-системы Serion ELISA classic Varicella Zoster virus IgG производства Virion\Serion, Германия. Сыворотки с содержанием антител более 100 мМЕ/мл расценивали как положительные. Динамику изменения доли иммунных лиц в разных возрастных группах определяли с помощью регрессионного анализа и оценивали по среднему темпу прироста. Для оценки риска инфицирования в различных возрастных группах использовали показатель относительного риска быть инфицированным (IRR). Результаты и обсуждение. Установлено, что выявляемость антител к вирусу IgG Varicella Zoster среди населения Республики Беларусь находится на уровне 85,5%, составляя от 82,0% до 89,7% в различных регионах страны. Уровень серопозитивных нарастает с возрастом (от 16,0% среди детей в возрасте 2 лет до 86,6% к 15-17 годам), составляет 95,4% в возрасте 18-25 лет, 97,1% в возрасте 26-35 лет и достигает 97,1-100% среди лиц более старшего возраста. К наиболее активному детородному возрасту 18-35 лет 3-5% женщин остаются восприимчивыми к этой инфекции. Расчетные данные по оценке риска инфицирования вирусом Varicella Zoster для лиц разного возраста свидетельствуют о том, что вероятность заболеть этой инфекцией наиболее высока среди детей 3-5 лет (IRR = 98,4). У взрослых она многократно снижается, но в возрастной группе 26-35 лет она все еще остается в два раза более высокой (IRR = 2,0), чем у лиц, достигших 46-летнего возраста. Заключение. Полученные данные по серопревалентности согласуются с данными по заболеваемости и позволяют предположить, что без социального управления эпидемическим процессом (вакцинация) потенциал инфекции остается достаточным для поддержания эпидемического процесса высокой интенсивности среди детей и средней интенсивности - среди молодых взрослых.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Chickenpox occupies a leading position in the structure of infectious pathology in the Republic of Belarus; 50,000-80,000 cases are registered annually in the country, including 2500-4500 cases among people over 15. Aims - to study the prevalence of IgG antibodies to Varicella Zoster virus among the population of the Republic of Belarus and assess the relative risk of infection for people of different ages. Materials and methods. The blood sera of 1190 people aged 2-75 from all 7 regions of the Republic of Belarus were investigated. IgG antibodies were detected using Serion ELISA classic Varicella Zoster Virus IgG, Virion\Serion, Germany. Sera with a n antibody concentration more than 100 mIU/ml were regarded as positive. The dynamics of the proportion of immune individuals by age was determined by regression analysis and estimated by the average rate of increase. To assess the risk of infection in different age groups, an indicator of the relative risk of being infected (IRR) was used. Results. It has been established that the prevalence of IgG antibodies to Varicella Zoster virus among the population of the Republic of Belarus is 85.5%, ranging from 82.0% to 89.7% in various regions of the country. The level of seropositive increases with age (from 16.0% among children aged 2 years to 86.6% by 15-17 years), it is 95.4% at the age of 18-25 years, 97.1% at the age of 26-35 years and remains at the level of 97.1-100% among older people. In the most active childbearing age of 18-35 years, 3-5% of women are susceptible to this infection. Varicella Zoster virus infection risk assessment data for people of different ages indicate that the probability of getting this infection is highest among children 3-5 years old (IRR = 98.4). In adults, it decreases many times, but in the age group of 26-35 years, it still remains two times higher (IRR = 2.0) than in people reached 46 years of age. Conclusions. The obtained data on seroprevalence are consistent with the data on morbidity and suggest that, without social management of the epidemic process (vaccination), the infection potential remains sufficient to maintain the high-intensity epidemic process among children, and medium intensity among young adults.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ветряная оспа</kwd><kwd>популяционный иммунитет</kwd><kwd>IgG антитела</kwd><kwd>относительный риск инфицирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chickenpox</kwd><kwd>population immunity</kwd><kwd>IgG antibodies</kwd><kwd>relative risk of being infected</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">Дронина А.
