它提到二重(superinfection)感染:
"Double infections with two different HBV genotypes have been known since typing was done serologically [29]. Subsequently, evidence of super infection with HBV isolates of the same or different genotype was described in chronic HBV patients [30]. Super infection was accompanied by acute exacerbation of the chronic disease. Using different methods for genotyping, several reports described high rates of double infection with two different HBV genotypes in all parts of the world. Using these methods double infections have been found in a range from 4.4% [31] to 17.5% [32] of HBV infected patients. Even triple infections with HBV of genotype A, B and C have been described in 0.9% of HBV infected intravenous drug users [32]. "
已知的,因为有两个不同的HBV基因型的双重感染血清学打字[29]。随后,超HBV感染的证据隔离在慢性HBV患者的相同或不同的基因型进行了说明[30]。超级感染,伴有的慢性疾病的急性发作期。用不同的方法进行基因分型,一些报告描述了高利率的双重感染,在世界各地有两个不同的HBV基因型。使用这些方法双重感染已被发现[31]从4.4%至17.5%[32]乙肝病毒感染的患者在一定范围内。甚至三倍的A,B和C基因型与HBV感染已被描述在0.9%的乙肝病毒感染的静脉吸毒者[32]
