Analysis of the Epizootiological Situation in the Amur Region in Autumn, 2013 Formed under the Influence of High Water over the Small Mammals

Objective of the work was to estimate the number and state of the small mammal populations after the summer flood, 2013 in the territory of the Amur Region and make short-term forecasting of the epidemiological situation development. Carried out was small animals capturing using Gero traps with bread as a bait. Epizootiological surveillance in August-September 2013 indicated that the numbers of small mammals did not differ from the average annual rates, but the process of active reproduction in the populations was being underway. In October-November a sharp increase in the animal abundance rate was registered, reproduction process terminated. Large-scale flooding resulted in the formation of local settlements with a high animal density. Stress, aggressiveness and food ration change along with seasonal migration of rodents into human buildings predetermined epizootiological and epidemiological premises for onset of natural-focal infections. Therewith the conclusion was made up that it was necessary to perform epizootiological monitoring of the small mammal populations and realization of measures aimed at the rodent extermination in human settlements in 2014

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

Epizootiological-and-Epidemical Situation on Tularemia in the South of Far East Region during the Period of River Floods

Carried out were epizootiological studies of the flooded areas of the Amur Region, the Khabarovsk territory, and the Jewish autonomous region in order to investigate the situation on tularemia in view of the river floods in August-September, 2013. Involved were specialized anti-epidemic teams from Irkutsk Research Anti-Plague Institute for works at the site of emergency. Therewith, analysis of the data of the epizootiological examination of the territories obtained in cooperation with specialists from the Rospotrebnadzor local Centers of Hygiene and Epidemiology, and results of laboratory investigations with application of bacteriological, immu­no­bio­logical and molecular-genetic methods indicated insignificant epizootic and epidemic activity of the natural tularemia foci. Given is the conclusion on epizootiological-epidemiological condition for tularemia in the flooded areas of the Amur River region and a short-term epizootiological forecast for 2013-2014, as well as recommendations concerning stabilization and improvement of epidemiological conditions in the region
