Surveillance of adult Aedes mosquitoes in Selangor, Malaysia

Abstract

Abstractobjective To determine the effectiveness of using sticky traps and the NS1 dengue antigen kit for the surveillance of Aedes mosquitoes for dengue control.methods Apartments were selected in a dengue-endemic area, and sticky traps were set to capture adult Aedes mosquitoes. NS1 dengue antigen kit was used to detect dengue antigen in mosquitoes, and positive mosquitoes were serotyped using real-time RT-PCR.results The sticky traps were effective in capturing Aedes aegypti, and a minimum of three traps per floor was sufficient. Multiple serotypes were found in individual mosquitoes.conclusion The sticky trap and the NS1 dengue antigen test kit can be used as surveillance tool in dengue control programmes. This proactive method will be better suited for control programmes than current reactive methods.

A Cross-sectional Survey on the Knowledge and Attitudes towards Zika Virus and its Prevention among Residents of Selangor, Malaysia

“…This study was conducted in Selangor in view of the reports suggesting a large number of cases related to mosquito-transmitted infections. [17] Moreover, Selangor carries the 60% burden of mosquito-transmitted infections reported nationwide due to a high density of Aedes mosquitoes in this region. [20] A purposive sampling approach was used to recruit the residents of Selangor for this study.…”

“…[16] In recent years, the epidemics of mosquito-borne disease have become critical in the state of Selangor. [17] In the first quarter of 2016, Selangor recorded the highest number of dengue cases (n=13,306) with highest fatality number (n=18) among other states. [18] World Health Organization has emphasized on the needs to provide much-needed education to communities about the preventive measures and potential complications associated with Zika virus.…”

A new paradigm for Aedes spp. surveillance using gravid ovipositing sticky trap and NS1 antigen test kit

“…The details of the study site were previously described [53]. The study spanned over two years from November 2013 to December 2015 (week 47 in 2013 to week 47 in 2015).…”

“…A detailed description of the gravid mosquito ovipositing in sticky trap (GOS trap) was provided in [53]. The cost of each trap is less than USD 1.…”

“…In a previous study conducted in an urban area in peninsular Malaysia, we showed that the infected Ae. aegypti mosquito was obtained from sticky non-insecticidal traps before the first case was reported [53]. The trap actually targets gravid Aedes mosquitoes which can be infected.…”
