The total RNA was extracted from two clinical blood samples of HFRS patients and the RNA was amplified by RT-PCRThe amplified DNA fragment of sample 613 involved nucleotides 1,471-1,873,and the sample 226 involved 540-1,244 nucleotides of M fragment of Hantaan virusThen the amplified PCR products were sequenced directlyThe sequencing results demonstrated that there was 84% identity between sample 613 and HV114 virus strain,but was 99% between sample 613 and HTN76-118 strainHowever,in sample 226,there was 95% sequence identity with HV114,82% with HTN76-118The results of phylogenetic tree analysis showed that HV613 was located in the same linage with HTN76-118,the HV226 was in the same linage with HV114 and A9
