Thus, controlling Aedes mosquito through the effective dengue control strategy had become the focus of government in controlling the spread of dengue virus. The aim of this paper is to prioritize the dengue control activities focuses on epidemic mitigation strategy. This strategy emphasizes on preventing the outbreak by implementing the high-impact activities at the beginning of outbreak period. The prioritized Fuzzy Technique for Order of Preference (FTOPSIS) model was developed based on the four dengue control activities namely fogging and larvaciding, premise inspection, public education and vector surveillance. Finding from the analysis shows that fogging and larvaciding, and premise inspection were the two appropriate controlling activities for epidemic mitigation strategy. As a conclusion, the FTOPSIS model provide a beneficial guidance to the health authorities in Malaysia on the most to the least importance factors should be given priority for the dengue control under epidemic mitigation strategy.

INTRODUCTION Dengue is a mosquito-borne disease cause by a single stranded virus that transmitted from one human to another through the contact with infectious mosquito known as a vector (Brachman, 1996; Centers for Disease Control and Prevention, 2010). The common mosquito vector for dengue virus are adult female Aedes Aegypti and Aedes Albopictus (Brady et al., 2013). Practically, dengue control strategy aims in reducing the population size of Aedes mosquito which act as a carrier for the dengue virus. However, issues such as the use of single strategy, the absent of climate-driven strategy and infrequent assessment for dengue control strategy had contributed to the ineffectiveness of these control strategy. Government will continue to rely on controlling Aedes mosquito even after an effective vaccine is available due to combination of both vaccine and controlling mosquito Aedes shows a successful result in controlling dengue (Beier et al., 2008; Achee et al. 2015). To date, Malaysia is still practicing a single strategy known as passive dengue surveillance system for controlling Aedes mosquito (Cheah et al., 2014). Based on this strategy, health practitioners are required to report within 24 hours from the initial encountered with the dengue infected people. The purpose is to notify the district health departments for further action such as investigation and implementation of chemical fogging and premise inspections (Packierisamy et al., 2015). However, depending on this strategy alone is not enough as dengue virus spread faster in the wider area in short period of time (Manorea, Hickmanna, Xub, Wearing & Hymanb, 2015). Thus, any delay in the notification process will slow down the implementation of the control activities and this result to the slow response in controlling the spread of dengue virus.
