DENV-2 is the cause of most dengue epidemics worldwide and is associated with severe cases.
We investigated arboviruses in 164 serum samples collected from patients presenting with clinical symptoms of dengue fever and 152 mosquito pools.
We detected the Asian II genotype of DENV-2 in humans and mosquitoes. Our results confirmed the circulation of the Asian II genotype in Brazil, in addition to the prevalent Asian/American genotype.
The detection of Asian II genotype of DENV-2 in mosquito pools collected in a forest park may be related to a spillback event of human dengue virus.
登革热病毒 2 型（DENV-2）是引发全球大多数登革热疫情的病原体，与重症病例有关。
我们调查了来自出现登革热临床症状的 164 份血清样本和 152 个蚊子池中存在的虫媒病毒。
我们在人类和蚊子中检测到了登革热病毒 2 型的亚洲 II 基因型。我们的结果证实了亚洲 II 基因型在巴西的流行，除了常见的亚洲/美洲基因型。
在森林公园采集的蚊子池中检测到登革热病毒 2 型的亚洲 II 基因型可能与人类登革热病毒的回溢事件有关。
