The epidemiological manifestations of TB incidence among HIV-infected and HIV-negative population of the Perm Region for 2014–2019 were studied. The frequency of TB in HIV-infected patients was determined depending on the level of immunodeficiency (96 patients) and viral load (61 patients).</p> <p><bold>Results</bold>. On average, the incidence of TB among HIV-infected persons was by 36 times higher than that of noninfected persons. Among those infected and noninfected with HIV, TB was registered significantly more often among adults, and mainly men. The incidence of TB among HIV-infected persons is higher among urban population, while HIV-negative – among rural residents. The incidence of TB in HIV-infected persons increases with an increase in the immunodeficiency and viral load.</p> <p><bold>Conclusions</bold>. Persons with HIV infection are at risk for TB. The incidence of TB in HIV-infected persons increases with an increase in immunodeficiency and viral load.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Оценить проявления эпидемического процесса туберкулеза у ВИЧ-инфицированных и частоту возникновения инфекции в зависимости от уровня иммунодефицита и вирусной нагрузки.</p> <p><bold>Материалы и методы.</bold> Изучены эпидемиологические проявления заболеваемости туберкулезом среди ВИЧ-инфицированных и ВИЧ-негативного населения Пермского края за 2014–2019 гг.

Среди инфицированных ВИЧ и неинфицированных туберкулез значительно чаше регистрировался среди взрослых, причем преимущественно среди мужчин. Заболеваемость туберкулезом ВИЧ-инфицированных выше среди городского населения, тогда как ВИЧ-негативных – среди сельских жителей.</p> <p><bold>Выводы. </bold>ВИЧ-инфицированные являются группой риска по заболеваемости туберкулезом.
