Seasonal and regional features of the distribution of rotavirus incidence in the Russian Federation

In the work there was performed an analysis of the indices of recorded incidence of rotavirus infection (RVI) in the territory of 40 subjects of the Russian Federation for the period 2008-2012. For the identification of the monthly peak of the incidence there was evaluated the temporal distribution of the relative indices of the RVI incidence within each subject of the observation. There was revealed the independent beginning of the winter-spring seasonal rise of the RVI incidence in three groups of territories of the Russian Federation (1 - Kirov, Kostroma, Nizhny Novgorod region; 2- Republic of Khakassia, Kemerovo region; 3 - Amur region). In the territory of the South and the North Caucasus Federal District (Krasnodarsky and Stavropolsky Krai, Rostov region) there was noted the second, summer-autumn seasonal rise in the RVI incidence. The obtained data provide an overview of the seasonal-geographical distribution of the RVI incidence in the territory of Russia in conditions of the absence of the use of rotavirus vaccines
