Abstract Content

Two confirmed human cases of Zika virus (ZIKV) were reported in district of Miri, Sarawak in 2016. Following that, a mosquito-based ZIKV surveillance study was conducted within 300-meter radius from the case houses. Mosquito surveillance was conducted using 5 different methods i.e. BG sentinel trap, modified sticky ovitrap, resting catch, larval surveillance and conventional ovitrap. A total of 527 and 390 mosquito samples were obtained from the case houses in two localities, namely Kampung Lopeng and Taman Shangri La, Miri Sarawak, respectively.  All mosquitoes collected were identified which consisted of 12 species. Ae. albopictus, both the adult and larval stages, was the dominant species. Resting catch method obtained the highest number of adult mosquitoes (67%), whilst ovitrap showed the highest catch for larval mosquitoes (84%). ZIKV was detected in both adults and larvae of Ae. albopictus together with adults of Cx. gelidus, and Cx. quiquefasciatus using real time RT-PCR technique. It was noteworthy that Aedes albopictus positive with ZIKV were caught and obtained from all 4 types of collection method. In contrast, Cx. gelidus and Cx. quinquefasciatus adults collected from sticky ovitraps were also found positive with ZIKV. This study provides the information regarding the potential vectors of Zika in Malaysia and assist vector control program managers to devise preparedness and contingency plan of prevention and control of the disease.
