Epidemiological Situation on Natural Focal Infectious Diseases of Bacterial and Viral Etiology in 2012 in the Territory of Siberia and Far East, and Prognosis for 2013
Analyzed is the incidence rate as regards natural focal infections of bacterial and viral etiology. Displayed is the data on the performed laboratory diagnostics of these infections in the territory of Siberia and Far East in 2012 and forecast of the epidemiological situation development in 2013. Analysis is carried out based on the data received by the Reference Center for surveillance over natural focal infections at the Irkutsk Research Anti-Plague Institute, from Rospotrebnadzor Institutions of Siberian, Far-Eastern and Ural Federal districts, as well as reviews and prognoses on the current state of natural foci of infections available from Altay, Tuva, Chita, Khabarovsk and Primorsk plague control stations
Epidemiological Characteristics of Enterovirus Infection in the Khabarovsk Territory under Hydrologic Emergency Situation
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
Results of Immunological Screening for Natural-Focal and «Exotic» Infectious Diseases among Certain Population Groups of the Khabarovsk Territory, the Amur Region and the Jewish Autonomous Region
Displayed are the results of examination of immuno-competent local population of the Khabarovsk Territory, the Jewish Autonomous Region, the Amur Region, as well as foreign residents living and temporarily working in the areas, on a wide range of natural-focal bacterial and viral infectious diseases including the causative agents of some “exotic” infections too. Investigations have been carried out with the participation of experts from the specialized anti-epidemic team No. 1 (Irkutsk Research Anti-Plague Institute), who worked in the Amur Region, and a group of laboratory-epidemiological specialists from the team No. 2 - deployed in the Khabarovsk Territory and the Jewish Autonomous Region during the flooding in August-September 2013. The total of 1335 blood sera samples has been tested using serological methods. The findings have revealed the presence of immuno-competent population in the three regions of the Far Eastern Federal district in reference to the agents of natural-focal infectious diseases: tularemia, leptospirosis, yersinioses, hemorrhagic fever with renal syndrome, human granulocytic anaplasmosis, tick-borne borrelioses, tick-borne viral encephalitis, Californian encephalitis serogroup, Sindbis, West Nile and Dengue fevers. Circulation of Batai and Crimean-Congo hemorrhagic fever viruses has not been revealed based on serological assays
Sanitary-Hygienic and Microbiological Monitoring over the Water Supply Sources and Surface Water Reservoirs during Natural Disaster in the Amur-River Territory
Emergency situation in summer 2013 due to flooding of extensive areas of the Russian Amur-River territories (including residential areas with different level of development of public services and amenities, agricultural land, sites of cattle grazing and stock-keeping) resulted in the increased microbiological, virologic and physical-chemical load upon water reservoir ecosystems. The results of monitoring over water supply sources, quality of drinking water and surface reservoir waters in the devastated territories were analyzed by the specialists from Rospotrebnadzor and specialized anti-epidemic teams No. 1 and 2. Complex approach presuming increase in extent and frequency of the examinations, performance of operative epidemiological analysis along with daily adequation of preventive and anti-epidemic measures allowed for taking control over the situation and to avoid epidemic complications as regards acute water-borne intestinal infections
