Проведен подробный статистический анализ количества экспо­зированных животных в очагах сибирской язвы в мире по суммированным данным ProMED и WAHIS за 2007–2017 гг. Учтены 195 очагов/вспышек сибирской язвы в мире с n = 12 423 голов животных, в среднем 64 головы на очаг, и широчайшей ам­плитудой лимитов от min 1 до max 2600. Наибольшая частота (p) инцидентности сибирской язвы (от 27 до 7) приходится на очаги, где экспозированным оказывается минимальное количество животных (от 1 до 7). Значения наиболее приближенных к реальности индексов очаговости сибирской язвы, рассчитанные с использованием статистически достоверной выборки ус­редненных вариант (количества очагов, экспозированных животных, смертности), для животных основных видов в пересчете на проценты зараженных в одной вспышке составляют в среднем 11% (от 0,6 до 19) для крупного рогатого скота, 4% (от 1 до 20) для мелкого рогатого скота, 7% (от 6 до 33) для лошадей.</p></abstract><trans-abstract xml:lang="en"><p>The index of nidality is the value quantitatively characterizing the activity of the animal infection nidus and grounded on the contagiousness, which is an immanent property of a contagious disease. A detailed statistical analysis of the number of animals being exposed in anthrax nidi globally, based on ProMED and WAHIS summarized data for 2007–2017, is given in the paper. 195 anthrax nidi/outbreaks with n = 12,423 animals (64 animal per outbreak in average) and the largest range of limits from min 1 to max 2600 were taken into consideration. The highest incidence (p) of anthrax (from 27 to 7) accounts for outbreaks, where minimum animals (from 1 to 7) were exposed. The indices of anthrax nidality, which are closest to reality and calculated using statistically reliable sample of average variants (number of outbreaks, exposed animals, mortality) for basic animal species, taken as a percentage of infected animals per one outbreak in average are 11% (from 0,6 to 19) for cattle; 4% (from 1 to 20) for small ruminants; 7% (from 6 to 33) for horses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сибирская язва</kwd><kwd>эпизоотология</kwd><kwd>индекс очаговости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anthrax</kwd><kwd>epizootology</kwd><kwd>index of nidality</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Публикация подготовлена при поддержке Програм¬мы РУДН «5-100»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гиперспорадичность инцидентов сибирской язвы / В.
