Preventing Zika disease with novel vector control approaches

The highest numbers of dengue cases in Latin America in the last few years have occurred in Brazil, Colombia, and Mexico. These countries have also faced outbreaks of chikungunya (2014-2015) and Zika (2015-2016). All three diseases are transmitted by the same mosquito vector, the aedes aegypti. The University of Ceará, Fundacion Santa Fe de Bogotá, and University of Yucatán have implemented vector control strategies to significantly reduce aedes aegypti.

This proposal aims to scale up participatory interventions targeting the surveillance, prevention, and control of aedes-transmitted diseases in three municipalities, namely Fortaleza (Brazil), Armenia (Colombia), and Merida (Mexico). Multidisciplinary teams will collect epidemiological and entomological indicators at the beginning, mid-term, and end of the project in a household sample of the intervention. The project will also assess the governance outcomes, and the costs and cost-effectiveness of the scaled intervention compared to the routine vector control program. A complementary feature will be the design and implementation of an innovative surveillance system that will engage the community to improve case detection.

Qualitative methods will be used to assess the acceptance of the intervention and to describe factors affecting the scaling up. State and municipal agencies, as well as NGOs, community-based organizations, and academic institutions will co-lead the scale-up of the interventions. Local and national resources have been committed to the implementation of the project. During the previous work of the principal research institutions in the three cities, strong links were developed with relevant strategic stakeholders that will facilitate implementation. The project is expected to make a significant contribution to the prevention of Zika, chikungunya and dengue disease through novel vector control and surveillance interventions that are potentially applicable in many other countries.
