Controlling the spread of vector-borne diseases (e.g., WNV, ZIKV) is the responsibility of a variety of departments across the country, including local health departments. In 2017, the National Association of County and City Health Officials (NACCHO), surveyed almost 2,000 local vector control programs nationwide and found that 84% of programs lack the capability or capacity to perform essential, evidence-based vector control activities. This presentation will discuss NACCHO's approach to providing technical assistance and capacity-building opportunities – to include best practices, lessons learned, and first-hand accounts from program participants.
