Abstract: Objective:To investigate the distribution patterns of arboviruses in Yunnan province near the China-Laos-Myanmar border, China, and to provide evidence for prevention and control of arboviruses diseases.
Methods:Mosquito samples were collected in Daluo county of Xishuangbanna Dai Autonomous Prefecture and Zhengdong county of Pu’er city in Yunnan province, 2012. Viruses were isolated from the samples by tissue culture, positive isolates were identified by RT-PCR with arbovirus species-specific primers, for further sequencing and phylogenetic analysis.
Results:A total of 17 species of mosquitoes from 6 genera were collected. A total of 24 strains of viruses were isolated from the mosquito pools and identified as Tembusu virus (TMUV) (2 strains), Japanese encephalitis virus (JEV) (3 strains), Getah virus (GETV) (2 strains), Banna virus (BAV) (4 strains), Densovirus (DNV) (9 strains) and Nam Dinh virus (NDiV) (3 strains).
Conclusions:The China-Laos-Myanmar border of Yunnan province is rich in species of mosquitoes and arboviruses.
