invasive snails and an emerging infectious disease: results from the first national survey on angiostrongylus cantonensis in china.eosinophilic meningitis (angiostrongyliasis) caused by angiostrongylus cantonensis is emerging in mainland china. however, the distribution of a. cantonensis and its intermediate host snails, and the role of two invasive snail species in the emergence of angiostrongyliasis, are not well understood.200919190771
newly recognized mosquito-associated viruses in mainland china, in the last two decades.there are four principal arboviruses in mainland china. two kinds of them are mosquito-borne viruses, namely japanese encephalitis virus and dengue virus, which lead to japanese encephalitis, and dengue fever/dengue hemorrhagic fever respectively; the other two are tick-borne viruses, namely tick-borne encephalitis virus and crimean-congo hemorrhagic fever virus (also known as xinjiang hemorrhagic fever virus), which contribute to tick-borne encephalitis and xinjiang hemorrhagic fever respective ...201121314994
distribution of mosquitoes and mosquito-borne arboviruses in yunnan province near the china-myanmar-laos border.abstract. economic development and increased tourism in the southern region of yunnan province in china, adjacent to several countries in southeast asia, has increased the likelihood of import and export of vectors and vector-borne diseases. we report the results of surveillance of mosquitoes and mosquito-borne arboviruses along the border of china-myanmar-laos in 2005 and 2006, and information associating several arboviruses with infections and possibly disease in local human populations. seven ...201121540383
spatial patterns of malaria reported deaths in yunnan province, china.malaria has been a heavy social and health burden in the remote and poor areas in southern china. analyses of malaria epidemic patterns can uncover important features of malaria transmission. this study identified spatial clusters, seasonal patterns, and geographic variations of malaria deaths at a county level in yunnan, china, during 1991-2010. a discrete poisson model was used to identify purely spatial clusters of malaria deaths. logistic regression analysis was performed to detect changes i ...201223269660
mosquitoes of western yunnan province, china: seasonal abundance, diversity, and arbovirus associations.the western borderland between yunnan province, china, and myanmar is characterized by a climate that facilitates year-round production of mosquitoes. numerous mosquito-transmitted viruses, including japanese encephalitis virus circulate in this area. this project was to describe seasonal patterns in mosquito species abundance and arbovirus activity in the mosquito populations.201324146951
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.201324499575
molecular epidemiology of japanese encephalitis virus in mosquitoes during an outbreak in china, 2013.japanese encephalitis virus (jev) can cause serious encephalitis and culex mosquitoes are the primary vector. in 2013, a je outbreak occurred in shandong province, china with 407 confirmed cases, including 11 deaths. an investigation on jev in mosquitoes during the outbreak was conducted. a total of 14,719 mosquitoes were collected at 3 sites. for the 12,695 culex tritaeniorhynchus mosquitoes, 88/201 pooled samples were positive by rt-pcr for the presence of the pre-membrane or envelope protein ...201424809635
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 ...201526030271
identifying determinants of oncomelania hupensis habitats and assessing the effects of environmental control strategies in the plain regions with the waterway network of china at the microscale.this study aims to identify the landscape ecological determinants related to oncomelania hupensis distribution, map the potential high risk of o. hupensis habitats at the microscale, and assess the effects of two environmental control strategies. sampling was performed on 242 snail sites and 726 non-snail sites throughout qianjiang city, hubei province, china. an integrated approach of landscape pattern analysis coupled with multiple logistic regression modeling was applied to investigate the ef ...025003174
mosquitoes established in lhasa city, tibet, china.in 2009, residents of lhasa city, tibet autonomous region (tar), china reported large numbers of mosquitoes and bites from these insects. it is unclear whether this was a new phenomenon, which species were involved, and whether these mosquitoes had established themselves in the local circumstances.201324060238
bayesian inference reveals host-specific contributions to the epidemic expansion of influenza a h5n1.since its first isolation in 1996 in guangdong, china, the highly pathogenic avian influenza virus (hpaiv) h5n1 has circulated in avian hosts for almost two decades and spread to more than 60 countries worldwide. the role of different avian hosts and the domestic-wild bird interface has been critical in shaping the complex hpaiv h5n1 disease ecology, but remains difficult to ascertain. to shed light on the large-scale h5n1 transmission patterns and disentangle the contributions of different avia ...201526341298
southernmost asia is the source of japanese encephalitis virus (genotype 1) diversity from which the viruses disperse and evolve throughout asia.although a previous study predicted that japanese encephalitis virus (jev) originated in the malaysia/indonesia region, the virus is known to circulate mainly on the asian continent. however, there are no reported systematic studies that adequately define how jev then dispersed throughout asia.201324069502

community knowledge and experience of mosquitoes and personal prevention and control practices in lhasa, tibet.since 2009, great public attention has been paid in lhasa city (tibet, china) to mosquito bites and accompanying inflammatory complications. however, the potential contribution of knowledge levels, experiences, disease control and preventive practices (kep) towards mosquitoes has not received much attention. to investigate community kep concerning mosquitoes in lhasa, a cross-sectional survey was undertaken in four sub-districts of urban lhasa in 2012. questionnaires were designed to collect inf ...201425250847
isolates of liao ning virus from wild-caught mosquitoes in the xinjiang province of china in 2005.liao ning virus (lnv) is related to banna virus, a known human-pathogen present in south-east asia. both viruses belong to the genus seadornavirus, family reoviridae. lnv causes lethal haemorrhage in experimentally infected mice. twenty seven isolates of lnv were made from mosquitoes collected in different locations within the xinjiang province of north-western china during 2005. these mosquitoes were caught in the accommodation of human patients with febrile manifestations, or in animal barns w ...201222649554
mosquitoes and mosquito-borne arboviruses in the qinghai-tibet plateau--focused on the qinghai area, china.an investigation was conducted to identify the distribution of mosquitoes and mosquito-borne arboviruses in the qinghai-tibet plateau, china from july to august in 2007. a total of 8,147 mosquitoes representing six species from three genera (aedes, culex, and anopheles) were collected in three locations (geermu city, altitude of 2,780 m; xining city, 2,200 m; minhe county, 1,700 m). six virus isolates were obtained including tahyna virus (tahv), liaoning virus, and culex pipiens pallens densovir ...201020348523
isolation and genetic characteristics of human genotype 1 japanese encephalitis virus, china, 2009.several studies have shown that the predominant genotype of chinese japanese encephalitis virus (jev) is evolving from genotype 3 to genotype 1. however, in recent years, almost all genotype 1 isolates were from mosquitoes, and genotype 1 has been less associated with human disease than genotype 3. this study reports the isolation of human genotype 1 jev and its genetic characteristics to provide additional insights into human je pathogens that are currently circulating in china.201121283590
