Dengue serotype 3 viruses were isolated from patients in Brazil from 2002 through 2004. On the basis of phylogenetic analyses, these isolates were assigned genotype 1. This genotype had never been reported in South America before. Its appearance indicates a major risk factor for dengue epidemics and severe disease.
2002年至2004年期间，在巴西从患者身上分离出了登革热3型病毒。基于系统发育分析，这些分离株被归为基因型1。这种基因型此前从未在南美洲被报道过。它的出现预示着登革热流行和严重疾病的一个主要风险因素。
