Key result
Rotavirus genetic analysis reveals a dominant genotype shift from G1P[8] to G4P[8] in Western Siberia.
Why the study?
Long-term monitoring of group A rotavirus isolates in Western Siberia is necessary to inform vaccine selection, improve diagnostics, and understand epidemiology and viral evolution.
Population
1416 rotavirus isolates from fecal samples of children admitted to hospitals in Novosibirsk and Omsk during four epidemic seasons 2007–2011
Design
Observational genetic analysis study

The study demonstrates the changing epidemiology of rotavirus genotypes in Western Siberia, highlighting the need for continuous monitoring to inform vaccine selection.
Zhirakovskaya et al. (2012) conducted an observational in Group A rotavirus infection (n=1,416). Group A rotavirus infection was evaluated on Rotavirus genotype distribution and phylogenetic analysis. Genetic analysis of 1,416 rotavirus isolates from children in Western Siberia revealed co-circulation of multiple genotypes, with a shift in dominance from G1P[8] to G4P[8] between 2008 and 2009.
