Dissemination of the West Nile Fever in the Russian Federation and in the World in 2010

Presented are the results of epidemiological analysis of the West Nile fever morbidity in the Russian Federation and all over the world in 2010. In 2010 West Nile fever outbreaks took place in Volgograd, Rostov and Voronezh Regions. For the first time West Nile fever was detected in Chelyabinsk Region, Kalmyk Republic, the Republic of Tatarstan, the Krasnodar Territory and the Voronezh Region. The II^nd genotype was determined in the process of genotyping of Volgograd and Rostov virus isolates. Analysis of West Nile fever morbidity in Europe in 2010 revealed that the genotypes of West Nile virus in the territory of Russia and in a number of European countries were similar. According to the retrospective and operative data it is determined that West Nile fever is endemic in the significant part of the territory of the Russian Federation. The absence of West Nile fever prophylaxis in the most part of the territory of the Russian Federation (training of the population, medical workers, preparation of the diagnostic means, working out of the treatment tactics and etc.) can lead to the significant social and economic losses in case of massive manifestations of this infection. Forecasting and assessment of the impact of future environment changes upon West Nile fever morbidity in the territory of the Russian Federation in the conditions of general trend of climate warming require studying of all the factors of virus-vector-person mechanism from the molecular to the population level by efforts of scientific and practical institutions of the Rospotrebnadzor.
