Molecular epidemiology of G9 rotavirus strains in children with diarrhoea hospitalized in Mainland China from January 2006 to December 2007.
Rotavirus was detected in 52% of 2328 stool specimens collected from children with acute gastroenteritis admitted to three sentinel hospitals in Mainland China from January 2006 to December 2007. G3P[8] (42%) was the most common strain. Despite being common globally, only 18 (2%) G9-positive samples were identified. The VP7, VP4, VP6, and NSP4 genes were sequences for 13 of the G9 strains with G9P[8] being most common and showing the same origin as G9 strains reported in other countries. One G9P[6] strain was possibly derived by reassortment between earlier Chinese G9 strains and more recent local P[6] strains.
