| a video clip of the biting midge culicoides anophelis ingesting blood from an engorged anopheles mosquito in hainan, china. | biting midges are hematophagus ectoparasites of insects, humans and other animals. culicoides (trithicoides) anophelis edwards1922 is a predator of engorged mosquitoes. | 2013 | 24499575 |
| a metagenomic survey of viral abundance and diversity in mosquitoes from hubei province. | mosquitoes as one of the most common but important vectors have the potential to transmit or acquire a lot of viruses through biting, however viral flora in mosquitoes and its impact on mosquito-borne disease transmission has not been well investigated and evaluated. in this study, the metagenomic techniquehas been successfully employed in analyzing the abundance and diversity of viral community in three mosquito samples from hubei, china. among 92,304 reads produced through a run with 454 gs fl ... | 2015 | 26030271 |
| prevalence of human immunodeficiency virus 1 infection in the last decade among entry travelers in yunnan province, china. | yunnan is not only considered the region with the most concerning human immunodeficiency virus (hiv)-1 prevalence, but is also the central hub for the spread of hiv-1 from southeast asia to the other provinces of china. yunnan has the highest proportion of entry travelers who have transmitted hiv from neighbored southeast asian countries to mainland of china. | 2015 | 25886406 |
| phylogenetic analysis of dengue virus reveals the high relatedness between imported and local strains during the 2013 dengue outbreak in yunnan, china: a retrospective analysis. | an outbreak of dengue virus (denv) occurred in yunnan province. more than 2,000 individuals were infected from august to november 2013. in this study, we aimed to characterize the origin and prevalence of denv in dehong prefecture of yunnan province using phylogenetic and evolutionary analyses of denv strains collected from local patients and foreign travelers. | 2015 | 25885572 |
| first isolation of dengue virus from lao pdr in a chinese traveler. | epidemic dengue activity has been demonstrated in several southern regions of china, but not in yunnan province, which borders countries in southeast asia where dengue is endemic. many dengue cases imported from southeast asia to yunnan have been reported, but dengue virus (denv) has not been isolated from any patients. this study is the first to report the isolation of denv from a chinese traveler returning to yunnan from lao pdr. | 2013 | 23497045 |
| a local outbreak of dengue caused by an imported case in dongguan china. | dengue, a mosquito-borne febrile viral disease, is found in tropical and sub-tropical regions around the world. since the first occurrence of dengue was confirmed in guangdong, china in 1978, dengue outbreaks have been reported sequentially in different provinces in south china transmitted by peridomestic ae. albopictus mosquitoes, diplaying ae. aegypti, a fully domestic vector that transmits dengue worldwide. rapid and uncontrolled urbanization is a characteristic change in developing countries ... | 2012 | 22276682 |
| multiple sources of infection and potential endemic characteristics of the large outbreak of dengue in guangdong in 2014. | a large outbreak of dengue, with the most documented cases, occurred in guangdong china in 2014. epidemiological studies and phylogenetic analysis of the isolated dengue virus (denv) showed this outbreak was attributed to multiple sources and caused by at least two genotypes of denv-1 (genotypes i and iii) and two genotypes of denv-2 (cosmopolitan and asian i genotypes). a retrospective review and phylogenetic analysis of denv isolated in guangdong showed that denv-1 genotype i strains were repo ... | 2015 | 26593240 |
| the effects of socioeconomic and environmental factors on the incidence of dengue fever in the pearl river delta, china, 2013. | an outbreak of dengue fever (df) occurred in guangdong province, china in 2013 with the highest number of cases observed within the preceding ten years. df cases were clustered in the pearl river delta economic zone (prd) in guangdong province, which accounted for 99.6% of all cases in guangdong province in 2013. the main vector in prd was aedes albopictus. we investigated the socioeconomic and environmental factors at the township level and explored how the independent variables jointly affect ... | 2015 | 26506616 |
