Abstract: VectorSurv is a publicly-funded, online interactive software system that provides tools for real-time collection, visualization, and analysis of data on vectors and vector-borne pathogens. The system addresses urgent needs for data modernization in the U.S. to deal with the growing threats of mosquito and tick-borne diseases. The system was initiated in 2006 to provide decision-support tools for West Nile virus and later to inform surveillance and control strategies for invasive Aedes aegypti and Aedes albopictus. VectorSurv now serves > 170 vector control and public health agencies in more than 18 U.S. states and territories, and the system is immediately scalable to any U.S. jurisdiction. Following CDC’s national framework for prevention and control of vector-borne diseases, VectorSurv provides interconnected, quality data to inform decision-makers at all levels – local, state, and national. This presentation will provide an update on VectorSurv’s online calculators and data visualization tools. These tools enable decision-makers to view and analyze near-real-time data to understand how vector populations and arbovirus risk respond to control efforts and environmental conditions.
