Epidemiological and molecular characterization of dengue viruses imported into Guangzhou during 2009-2013.

ABSTRACT:

Background

Dengue virus causes one of the most significant infectious diseases in tropical and subtropical regions, notable number of which is imported into China every year.

Results

In this study, the molecular epidemiologic and phylogenetic analyses of dengue cases imported into Guangzhou in South China during 2009-2013 were conducted. During that period, 46 imported dengue cases were identified, including four serotypes. Most of the dengue patients were travelling from Southeast Asia, South Asia and Africa. The envelope (E) genes of 20 imported dengue viruses introduced from 13 countries and regions, were sequenced and used for phylogenetic analyses. The results indicated that the DENV-1 genotype I and DENV-2 Asian genotype I were the most predominant DENV strains, which
