Abstract
<title>Abstract</title> <p> Background Digital technologies are increasingly used in public health to improve data management and strengthen disease-control operations. This study describes the design, development, and field testing of a web-based software system—Digital Surveillance of Vector Control (DSVC)—to monitor and evaluate vector control programs. The system was deployed during a large-scale intervention using a novel larvicidal/adulticidal protective coating (PC) applied to domestic water containers, the main larval habitat of dengue-transmitting <italic>Aedes</italic> mosquitoes in many tropical cities. A field study was conducted in Cúcuta and Los Patios, Colombia, to assess the potential of DSVC to reduce data processing time, improve accuracy, and support timely decision-making. Methodology: DSVC was developed to optimize data processing and monitoring vector control activities. It was tested under real operational conditions by integrating data collected by community volunteers during visits to approximately 8,000 households. Two data-collection methods were compared: traditional paper forms and the Epicollect5 mobile application. The principal investigator monitored real-time data processing, analysis, and visualization through DSVC. In-depth interviews with municipal data management engineers assessed the system’s potential integration into local health services. Focus group discussions with community volunteers and vector control technicians explored acceptance, usability, and perceived advantages and limitations of Epicollect5. Results DSVC reduced data processing time and improved accuracy compared to paper-based workflows. The system efficiently managed large data volumes and enabled rapid aggregation and visualization of data. Municipal vector control technicians reported that DSVC met key requirements for monitoring vector control activities. Interviews and focus groups indicated positive acceptance of digital tools, highlighting their potential for adoption in routine programs. Epicollect5 facilitated integration of paper-based and digital data, reduced errors, and accelerated data capture. However, fieldwork revealed risks of device theft and persistent preference for paper forms in some neighborhoods. Conclusion DSVC and Epicollect5 enhanced the efficiency of data collection and analysis, enabling faster and more targeted responses. Digital tools represent a significant advancement for optimizing vector control programs. Municipal departments identified the system’s potential for future integration, pending administrative decisions. User acceptance, operational feasibility, and clear workflows are essential for maximizing the impact of digital tools in vector control. </p>
