Epidemiological Features of Enterovirus Infection during Flood on the Territory of Jewish Autonomous Region

Abstract

Long-term manifestations of epidemiological process of enterovirus infection in the Jewish Autonomous Region were similar to those in the Khabarovsk Territory, though with a lower intensity. After establishment of emergency situation regime, in view of the rainfall flooding in 2013, enterovirus morbidity rate had been increasing within three weeks duration, then started to fall rapidly. Clustered cases of enterovirus infection were not registered. Viral serous meningitis ratio was insignificant as minor forms of the disease prevailed; coxsackie virus A-9 and echovirus-6 dominated. During the flood period isolated from samples of patients with minor forms of enteroviral disease were three enterovirus strains, type 71, sub-genotype C4a, possessing a high degree of genetic similarity to the Chinese ones, 2010-2011. All in all impact of the natural disaster on the epidemiological situation on enteroviral infection in the Jewish Autonomous Region turned to be insignificant.
