Epidemiological Characteristics of Enterovirus Infection in the Khabarovsk Territory under Hydrologic Emergency Situation

Abstract

The paper contains the data on the role of high waters (2013) in changing epidemiological situation on enterovirus infections in the Khabarovsk Territory. The incidence rate in the region was characterized by the significant increase even before the flood, 2013. Thus, two peaks of enterovirus morbidity curve were identified for the period of a week: one - more intensive, another - coincident with flood outbreak. Enterovirus epidemiological process was notified by the changes in clinical picture among the infected population and cohort age-related structure. The percentage of the patients with enterovirus infections in the foci clusters and the index of people infected due to possible exposure to shattering impact of the flood, turned out to be low. However, revealed was high rate of heterogeneity of the circulating enterovirus strains, non-specific for the Khabarovsk territory and mostly originating from countries of Asia-Pacific region - coxsackie A viruses, which might stand for a possible cause of unfavorable epidemiological situation in 2013.
