GrabMart transaction data could supplement clinical surveillance because over-the-counter demand sometimes shifts before confirmed case reports. The concept aggregates eligible purchases, maps SKUs to broad symptom classes, and compares demand series against seasonal and historical baselines to produce an Early Outbreak Detection Index. Public health experts would review that aggregate signal alongside independent evidence, and the method excludes identity linkage and individual-level health inference. Statistical evaluation would need sensitivity, false-alert rate, calibration, geographic stability, and retrospective testing against approved public health data, with ongoing monitoring for catalogue changes, promotions, and shifting purchasing behaviour. Privacy relies on data minimisation, coarse geography, aggregate time windows, minimum-count thresholds, and possibly differential privacy under an approved budget; the authors state this is early-stage planning only, with no deployment, measured performance, or integration claimed.
