New Cost-Benefit of Brazilian Technology for Vector Surveillance Using Trapping System
The recent introduction of chikungunya and Zika virus and their subsequent dispersion in the Americas have encouraged the use of novel technologies for adult Aedes surveillance to improve vector control. In Brazil, two platforms for surveillance of eggs and gravid Aedes aegypti have been developed. First, it consists of using data of sampling of eggs in ovitraps associated with GIS technologies to monitor Aedes spp. populations. Although effective, it is not realistic to use in a large-scale epidemic scenario as it requires a large amount of human resources for field and laboratory activities. Second, it consists of trapping female Ae. aegypti citywide at fine spatial and temporal scales for vector surveillance (MI-Aedes) to detect high Aedes infestation areas using a GIS environment and the identification of arbovirus-infected trapped mosquitoes by RT-PCR (MI-Virus platforms). Such integration of continuous vector surveillance and targeting vector control in hotspot areas is cost-effective (less than US$ 1.00/person/year), and it has been shown to reduce mosquito population and prevent dengue transmission. The main advantage of the MI-Aedes platform over traditional mosquito surveillance is the integration of continuous vector monitoring coupled with an information technology platform for near real-time data collection, analysis, and decision-making. The technologies also provide data to model the role of climate on the vector population dynamics.
