| emergency vector control in a denv-2 outbreak in 2002 in pingtung city, pingtung county, taiwan. | this paper reports the strategy and effectiveness of an emergency control program conducted in pingtung city, taiwan in response to dengue outbreaks. in our control strategy, we carried out 3 insecticide space sprays with an interval of 6-7 days and 2 source reductions to cover the entire duration of dengue virus exposure in humans and mosquito vectors. the control effect was demonstrated by a significant reduction in the breteau (51.1%) and larval (80.0%) indices, but no such effect was demonst ... | 2007 | 17881866 |
| the use of fine nets to prevent the breeding of mosquitoes on dry farmland in southern taiwan. | the stagnate water stored in buckets traditionally used by farmers in southern taiwan to irrigate their dry farmland, serves as favorable breeding ground for aedes aegypti, the vector of the dengue virus. the public health bureau there distributed fine nets to the farmers to cover their buckets to reduce vector breeding sites. the goal of this study was to compare the container index (ci) in alian and tianliao townships, kaohsiung county in southern taiwan over a 2-year period, for 1 year before ... | 2009 | 19183549 |
| characteristic of dengue disease in taiwan: 2002-2007. | taiwan's dengue outbreaks have a unique type of transmission: starting by import from abroad in early summer, spreading out locally, and ending in the winter. this pattern repeats every year. most of the dengue patients are adults, with dengue fever peaking in the 50-54 year age range, and dengue hemorrhagic fever in the 60-64 year age range. two patterns of dengue infection were found: denv-2 in 2002 with 74% of secondary infection in contrast to non-denv-2 (denv-1 or denv-3) in 2004-2007 with ... | 2010 | 20348527 |
| screening of mosquitoes using sybr green i-based real-time rt-pcr with group-specific primers for detection of flaviviruses and alphaviruses in taiwan. | surveillance for infectious agents carried by mosquitoes is important for predicting the risk of vector-borne infectious diseases. in this study, a method was established to mass-screen mosquitoes for viral infections. the assay detected the viral load of 4 dengue virus (denv) serotypes (denv-1, denv-2, denv-3, and denv-4), the japanese encephalitis virus (jev), the sindbis virus and the chikungunya virus at 1pfu/ml (determined by real-time rt-pcr) in 36.64-43.45 cycles. this method was applied ... | 2010 | 20471427 |
| screening of dengue virus in field-caught aedes aegypti and aedes albopictus (diptera: culicidae) by one-step sybr green-based reverse transcriptase-polymerase chain reaction assay during 2004-2007 in southern taiwan. | we carried out virological surveillance of dengue virus (denv) in field-caught aedes mosquitoes during 2004-2007 to estimate the monthly prevalence of infected females in dengue high-risk areas of taiwan. a total of 92,892 aedes aegypti (43,133 females and 49,759 males) and 79,315 aedes albopictus (57,319 females and 21,996 males) adults were collected, grouped into 25,654 pools, and processed for virus detection using a one-step sybr green-based real-time reverse transcriptase-polymerase chain ... | 2010 | 21128850 |
