Arboviruses transmitted by Aedes mosquitoes are of great concern to public health across the world. Aedes aegypti and Aedes albopictus are of particular concern because of their close association with humans. These two species are vectors of several arboviruses including yellow fever, dengue, chikungunya and Zika viruses. Brazil is one of the countries that is most impacted by these vectors and the pathogens they transmit. Knowledge about the seasonal changes in vector activity is important as it informs the timing of intervention strategies. To assist ongoing efforts in Brazil to anticipate when Aedes vector hazards and the risks of arbovirus transmission are highest, we developed a simple Excel-based tool that uses monthly habitat suitability models to display various aspects of average Aedes seasonality for user-defined second order administrative areas of Brazil. Our aim was to create an easy to use interface between monthly vector habitat suitability models and areas of interest for those lacking the time and skills to use learn and deploy GIS software. Note: The spreadsheet provided uses published habitat suitability models, however our methodology allows for the use of any habitat suitability model covering Brazil. An article published in the U.S. Army Medical Department Journal (January to June 2018) is available here that summarizes this work.
