This medical illustration depicts a classic presentation of primary or recurrent oral herpes simplex virus (HSV-1) infection, showing grouped vesicles along the vermilion border of the lower lip. The lesions appear as small, translucent, erythematous papules progressing to pustules, often preceded by tingling or burning sensations. Such outbreaks are typically triggered by stress, immunosuppression, or UV exposure.
