# Gvsdb Grapevine Virus

The Grapevine Virus and Symptom Database (GVS-DB) holds 3,195 photographs of grapevine leaves from vineyards around Ensenada, Baja California, Mexico, sampled in 2022 and 2023 (CICESE), in two classes as published: asymptomatic_or_negative (1,534) and symptomatic_or_positive (1,661) for grapevine leafroll disease and grapevine red blotch disease. Most photographs show a single detached leaf laid on a white board, with a minority of in-vineyard canopy shots; symptomatic leaves show the reddening and interveinal discolouration of these virus diseases. The record also ships a spreadsheet of real-time PCR diagnostics (GLRaV-1 to GLRaV-4 and GRBV) per sampled vine, but the photographs are numbered sequentially and do not reference the sample codes, so the PCR results cannot be attached to individual images; the class folder is the only per-image label and it mixes visible symptom status with molecular status. The dataset contains 3,195 images across 2 classes: asymptomatic_or_negative, symptomatic_or_positive.  
Images per class:
- asymptomatic_or_negative: 1,534
- symptomatic_or_positive: 1,661
