Improving the West Nile Virus Surveillance Program


Impact Statement: 
Kendall County Health Department implemented successive PDSA cycles to better protect their population from West Nile Virus. The QI activities eventually led to a nearly 200% increase in the number of mosquito tests performed. Moreover, the implementation of a GIS management system has led to more effective and targeted surveillance efforts. Finally, the program has expanded to address Zika virus and Lyme disease. Notably, all of these achievements occurred with level funding.

Staff of KCHD’s West Nile virus surveillance program realized a need to increase the quality of surveillance data and effectively identify areas of concern to assist with implementing control measures related to the West Nile virus. Since 2013, program staff conducted a series of PDSA cycles to make incremental improvements in program activities. Over time, the number of mosquito tests performed has increased 187%. GIS software was used to track locations of dead bird sightings in real time throughout the season, leading to smarter trap placement, better surveillance, more accurate tracking of disease progression, and better targeted outreach. Developing relationships with the Kendall County Forest Preserve District, municipalities, and townships in Kendall County was an essential part of the project. These relationships facilitated trap placement in new areas and provided opportunities for education about the West Nile virus and prevention strategies.
