Molecular epidemiology of rotavirus diarrhoea among children in Haiphong, Vietnam: the emergence of G3 rotavirus.
From September 2006- October 2007 hospital-based surveillance was conducted in Haiphong, Vietnam among children less than age 5 years hospitalized for diarrhoea to determine the distribution of G and P types and electropherotypes of rotavirus. Of note, the emergence of G3P[8] was identified and the strain was predominant among rotaviruses detected. More than 90% of G3P[8] electropherotyped strains shared an identical electropherotype, indicating they were of a single origin and their VP7 sequences were similar to those reported from Japan and China. This abrupt emergence of a novel G3 strains underscores the continued need for quality rotavirus surveillance.
