47 - Arboviral surveillance and outbreak response in California

California’s statewide arbovirus surveillance program operates as a “three-legged stool” involving long-standing, close partnerships among the California Department of Public Health, the member agencies of the Mosquito and Vector Control Association of California, and the University of California, Davis. The program monitors endemic zoonotic arboviruses (West Nile, St. Louis encephalitis, and western equine encephalomyelitis viruses) and anthroponotic viruses that have the potential to emerge in the state (dengue, chikungunya, and Zika viruses). This presentation will cover (1) various elements of the statewide surveillance program, (2) methods used for collecting and testing samples from mosquitoes, sentinel chickens, and dead bird carcasses, (3) coordination efforts to ensure consistency of statewide surveillance results, (4) real-time data management, analysis, and reporting via VectorSurv for public-health and vector-control decision support, and (5) the statewide response plan for risk assessment and control of arboviral outbreak threats.
