Hand-foot-and-mouth disease is caused by a coxsackie virus. Outbreaks are most common in the summer and fall months. The condition is occasionally associated with meningitis. Painful skin and oral lesions are often preceded by a period of malaise and fever. The patient often presents once the lesions appear on the lips and/or oral mucosa. The lesions erupt as vesicles, which later ulcerate. Multiple lesions are located on the lips and oral mucosa. As the condition's name implies, the lesions often appear on the hands and feet as well as in the mouth.
