Epidemiological and etiological characteristics of enterovirus infection in the Khabarovsk krai in year 2022
Abstract
Analysis of epidemiology and etiology of epidemic elevation of enterovirus incidence during year 2022 in the Khabarovsk krai was performed. After low levels of enterovirus infection (EVI) incidence in the year 2020 and following years 2021 and 2022 in the Khabarovsk krai it was shown that the diseases started to re-emerge. Incidence levels (per 100 thousand of population) during year 2022 has exceeded long-term average incidence by 75.1%. Epidemiological characteristics of the outbreak were typical for EVI: summer-fall seasonality, involvement of children population, different clinical forms. At the same time, predominance of meningeal syndromes among infected was a special trait of the outbreak. Etiological analysis via PCR showed up to 36.0% virus carriers among patients with suspected EVI. Analysis of 231 patients with EVI showed cytopathogenic agents in cell culture. Serotypes ECHO 6, ECHO 13 of the virus were identified.
