| aedes aegypti in ho chi minh city (viet nam): susceptibility to dengue 2 virus and genetic differentiation. | aedes aegypti is the principal vector of dengue viruses, responsible for a viral infection that has become a major public health concern in asia. in viet nam, dengue haemorrhagic fever was first detected in the 1960s and is now a leading cause of death in childhood. we studied the variability in competence of ae. aegypti as a vector for dengue 2 virus and genetic differentiation in this mosquito species. twenty mosquito samples collected in 1998 in ho chi minh city were subjected to oral infecti ... | 1999 | 10717737 |
| temporal genetic variation in aedes aegypti populations in ho chi minh city (vietnam). | aedes aegypti, the main vector of dengue viruses in asia, displays variation in population density over time. the larval habitats of this species being unevenly distributed and transient (depending on cycles of drought and flood), the forces generating temporal variation in gene frequencies in populations are studied. we sampled seven mosquito populations from ho chi minh city (vietnam) and its suburbs on five occasions between april 1999 and august 2000. we investigated genetic variation by stu ... | 2002 | 12080364 |
| genetic differentiation of the dengue vector, aedes aegypti (ho chi minh city, vietnam) using microsatellite markers. | dengue haemorrhagic fever emerged in the 1950s and has become a major public health concern in most asian countries. in vietnam, little is known about the intraspecific variation of the vector and its consequences on vectorial capacity. here we report the use of microsatellite markers to differentiate aedes aegypti populations in ho chi minh city, a typical, overcrowded asian city. six microsatellite loci, with 5-14 alleles per locus, were scored in 20 mosquito samples collected in 1998 in ho ch ... | 2002 | 12207714 |
| [aedes aegypti, vector of the dengue virus: spatio-temporal structure of its genetic variation]. | aedes aegypti is the main vector of dengue viruses. methods for limiting the spread of dengue outbreaks are currently based on vector control. estimates of population genetic organization and gene flow with respect to vector capacity have provided great insights into dengue epidemiology. in vietnam, dengue hemorrhagic fever was detected in the 1950's and becomes today the major problem of public health. among factors influencing dengue epidemiology, ecological disturbances have a direct impact o ... | 2002 | 12669664 |
| the economic impact of dengue hemorrhagic fever on family level in southern vietnam. | dengue fever is a viral infection transmitted by mosquitoes (aedes aegypti). who estimates that 40% of the world's population live in areas endemic for dengue fever, and that there are approximately 50 million cases of dengue infection worldwide every year. this study aims to measure the economic consequences of dengue hemorrhagic fever in southern vietnam on family level. estimating the economic impact of dengue fever/dengue hemorrhagic fever is important in order to prioritize resources for re ... | 2007 | 17521539 |
| effect of existing practices on reducing aedes aegypti pre-adults in key breeding containers in ho chi minh city, vietnam. | this study aimed to evaluate the effects of existing practices of residents in reducing pre-adult aedes aegypti (l.) infestation and to assess the effect of dengue-related knowledge on the practices. a house-to-house survey was conducted in two areas with different socioeconomic status in ho chi minh city between october and november 2007. some residents in both the areas used covers on the productive containers such as the jars and plastic buckets (i.e., 58% and 81% in the two study areas), and ... | 2009 | 19407119 |
