摘要

登革热是一种主要的病媒传播感染，在热带地区的城市社区造成大规模疫情。2010- 2014年期间;从位于厄瓜多尔西北部地区的一家半农村社区医院采集了434份发热患者血清样本。采用逆转录酶PCR检测登革病毒(DENV);共有48个样本呈登革热阳性。2010 - 2013年检测DENV-2型和DENV-3型，2013-2014年检测DENV 4种血清型。令人惊讶的是，我们的结果与在整个厄瓜多尔海岸城市中心进行的调查形成了对比，在2010-2013年期间，DENV-1、DENV-2和DENV-4流行，2014年只有两种血清型(DENV-1和DENV-2)。这些结果表明，半农村社区的登革热病毒并非起源于厄瓜多尔的城市。

Dengue Serotype Differences in Urban and Semi-rural Communities in Ecuador

Dengue is a major vector-borne infection causing large outbreaks in urban communities in tropical regions. During the period 2010- 2014; 434 serum samples from febrile patients were collected from a semi-rural community hospital located in the norwestern region of Ecuador. Dengue virus (DENV) was investigated by reverse transcriptase PCR; a total of 48 samples were positive for dengue. During our study we detected DENV-2 and DENV-3 from 2010 to 2013 and the four DENV serotypes during the period 2013-2014. Surprisingly, our results contrasted with surveys carried out in urban centers throughout the Ecuadorian Coast in which DENV-1, DENV-2 and DENV-4 were prevalent during years 2010-2013 and only 2 serotypes (DENV-1 and DENV-2) in 2014.These results suggest that dengue viruses in semi-rural communities didn’t originate in the Ecuadorian cities.
