A medical cinematic illustration showing a patient undergoing a colonoscopy in a modern clinical setting. On the monitor, the endoscopic camera shows smooth, healthy-looking intestinal mucosa — clean and without evidentiary signs. But layered symbolically in the background (or faded into the intestinal wall), tiny parasitic organisms like protozoa and helminths are subtly depicted hiding between folds, or embedded deeper in tissues, undetectable by the surface-only scope. The doctor gestures with confidence, while the patient remains unaware that the test might not reveal the true underlying infection. The scene has cool clinical lighting, shallow depth of field, and realistic anatomy, overlaid with symbolic, almost ghost-like imagery of parasitesemoji
