Abstract
INTRODUCTION: In Malaysia, dengue is predominantly an urban disease and Ae. aegypti is the main reported vector. Gombak is an urban district in Selangor with multiple recurring dengue outbreak ecosystem. The assessment of practicality of ovitrap as a surveillance system was studied to appraise the importance of ovitrap as an early detection tool in dengue prevention and outbreak control mechanism. METHODS: This study utilised Bandar Baru Selayang (Zon A) data, which derived from ovitrap surveillance records from February to November 2018, and all registered dengue confirmed cases from 1st January 2016 till 31st March 2019, extracted from e-dengue. Google Earth was used to map cases and Aedes sp. positive area. For ovitrap surveillance, a fixed number of 100 ovitraps were placed and analysed weekly. Preventive activities were executed each time when positive Aedes sp. identified in ovitrap. RESULT: Data was analysed using Microsoft excel. During the 40-week study, positive ovitrap with Aedes sp was identified intermittently for 28 weeks. It was noted 86% of the ovitrap placed outdoor was positive compared to only 14% placed indoor. Preventive activities implemented were able to avert cases successfully for the first 21 weeks and reduced severity of outbreak by 75% compared to same time period for 2016 and 2017. DISCUSSION: Ovitrap is an effective and promising tool in dengue surveillance provided prompt and effective preventive activities are executed.
