近年来的一些研究表明全球范围内A组轮状病毒是成人腹泻的重要病原。本文参考国内外成人A组轮状病毒的人群分布、基因分型等相关文献,结果发现不同国家和地区急性胃肠炎患者中A组轮状病毒的检出率和流行季节等差异较大。在成人腹泻患者中,年龄较大的患者感染轮状病毒发病的危险高。新型别的轮状病毒陆续被发现,目前已有27个G和37个P基因型被确定,其中G9P[8],G1P[8],G2P[4],G3P[8]和G4P[8]为世界范围内常见的五种基因型组合,不同的国家和地区,优势基因型有差别,而且同一地区不同年份优势基因型也可能发生改变。
In recent years, some studies have shown that group A rotavirus is an important cause of adult diarrhea in the world. This article refers to the domestic and international adult group A rotavirus population distribution, genotyping and other relevant literature, found that different countries and regions in patients with acute gastroenteritis A group of rotavirus detection rate and the prevalence of seasonal differences. In adults with diarrhea, older patients have a higher risk of developing rotavirus infection. A new type of rotavirus has been discovered in succession. At present, 27 G and 37 P genotypes have been identified, of which G9P [8], G1P [8], G2P [4], G3P [8] and G4P [8] For the five genotypes common in the world, the dominant genotypes are different in different countries and regions, and the dominant genotypes in different years in the same region may also change.
