Aedes Mosquito Control and Surveillance in the Pacific

Abstract

Introduction: Mosquitoes of the genus Aedes transmit dengue, Zika and chikungunya viruses, and the incidence of these diseases is increasing in the Pacific. This can be attributed to increased movement of people and goods, unplanned urbanisation, and global warming, among other factors. As vaccines are unavailable, we rely on vector control programs to prevent disease transmission. This study aimed to evaluate current practice in vector control and surveillance in 10 Pacific Island countries and identify evidence-based vector control interventions and surveillance methods for use in these countries. Methods: This study was conducted in preparation for TechCamp New Zealand, 24-26 January 2018, which aimed to work with stakeholders from 10 Pacific nations to reduce the spread of vector-borne diseases in the region. We conducted a literature review of published reviews and meta-analyses evaluating Aedes control and surveillance to find methods appropriate for use in Pacific Island countries. We collected information regarding current Aedes mosquito control and surveillance practice in 10 Pacific countries from TechCamp participants, through a survey, presentation and interview. Findings: Combinations of vector control interventions, applied appropriately, can prevent disease transmission. Although such programs exist in the Pacific, some interventions do not currently follow best practice. Key barriers to implementing evidence-based practice include lack of targeted education, internet and network coverage, personnel and expertise. Conclusions: Future goals for the region include the adaptation of current practice to evidence-based practice, and the development of vector and risk factor surveillance for targeted mosquito control. New developments should be sustainable and not reliant on internet or network real-time coverage. Education should be targeted to local communities to maximise community participation.
