VectorSurv Vectorborne Disease Surveillance System

VectorSurv is an integrated vector-borne disease surveillance platform operated by the Davis Arbovirus Research and Training (DART) Lab at UC Davis, in partnership with the Mosquito and Vector Control Association of California (MVCAC) and the California Department of Public Health (CDPH).^[1] The platform serves as the primary data management and risk analysis system for mosquito control districts and public-health agencies across the United States, covering 390+ agencies in 36 states and territories with more than 1,300 users.^[1]

Earth observation data is integral to the platform's risk surface outputs. MODIS land-surface temperature is ingested via NASA's Terrestrial Observation and Prediction System (TOPS) to model mosquito thermal suitability; NLDAS temperature and hydrology products drive seasonal and spatial estimates of mosquito reproductive potential; and SMAP soil moisture data is listed as an input to the risk surface computation in platform documentation accessed in 2026.^[2] Risk surfaces are updated daily, combining EO-derived environmental parameters with ground-collected trap data, arbovirus pool testing, and insecticide resistance monitoring.

Key outputs include West Nile Virus risk surface maps, invasive mosquito species distribution maps (including Aedes aegypti and Ae. albopictus), Vector Index and Pool Infection Rate calculators, abundance anomaly tracking, and a data API for integration with state and local health workflows.^[3][4] The platform has been in continuous operation since 2006 and has received NASA Applied Sciences funding since 2015, alongside support from CDC, NOAA, and the State of California.^[2]
