title: [Molecular characterization and phylogenetic analysis of enteroviruses inducing the outbreaks and seasonal rises of morbidity in different regions of the Republic of Belarus].
abstract: As shown by the results of the analysis, viruses ECHO 30 circulating over the period of the last 8 years in Belarus, belonged to 3 different genetic subtypes which earlier or simultaneously circulated in other European states. The outbreaks of enterovirus infections (EVI) were facilitated by the appearance of a genetic viral subtype, relatively "new" for human population, and which had not earlier circulated on this territory. Thus, the development of outbreak morbidity in 2003 was caused by a change in the dominating subtype of virus ECHO 30, which caused the outbreak of 1997. The relatively "soft" rise of morbidity in 2004 was due to the continued circulation of the same subtype of virus ECHO 30, that in 2003. The largest outbreaks of EVI in the Republic of Belarus had a number of considerable differences: the outbreak of 1997 in Gomel was characterized by the genetic heterogeneity of infective agents, being simultaneously geographically localized within the limits of one city. However, during the outbreaks of 2003 the circulation of genetically closely related viruses of the one subtype among the population of geographically remote regions of the country was registered.
