The distribution of the G type of human rotavirus was surveyed in Thailand between July 1993 and June 2007. A significant yearly change in the distribution of the G type distribution was found. From 1993-1994 to 1998-1999, the G1 type was the most dominant. In 1999-2000, G9 began to appear at a high frequency. In 2000-2001, 2001-2002, and 2002-2003, G9 was very common. In 2003-2004, G1 became the most prevalent type again, and since then it has been detected at the highest frequency. G12 strains, which were first detected in 1998-1999, were also found in 2004-2005 and 2006-2007. The G4 and G3 types were moderately prevalent in 2001-2002 and 2004-2005, respectively. Nucleotide sequence analysis of the VP7 genes of the G9 and G12 strains which reemerged in Thailand showed that they were each similar to the contemporary strains in other countries.
本研究于 1993 年 7 月至 2007 年 6 月在泰国调查了 G 型人轮状病毒的分布情况。发现 G 型分布存在显著的年度变化。1993-1994 年至 1998-1999 年，G1 型是最主要的类型。1999-2000 年，G9 开始高频出现。2000-2001 年、2001-2002 年和 2002-2003 年，G9 非常常见。2003-2004 年，G1 再次成为最流行的类型，此后一直以最高频率检测到。1998-1999 年首次检测到的 G12 株也于 2004-2005 年和 2006-2007 年被发现。2001-2002 年和 2004-2005 年 G4 和 G3 型分别中度流行。在泰国重新出现的 G9 和 G12 株的 VP7 基因核苷酸序列分析表明，它们各自与其他国家的当代株相似。
