The hand, foot and mouth disease is caused by the coxsackievirus, especially type A 16. Mostly occurring in children under 10 years, the highly contagious disease shows symptoms like small 1-3 mm erythematous papulo vesiclular eruptions over hands, feet and knees maybe accompanied by low grade fever and sore-throat. In the oral cavity, on the buccal mucosa, occur ulcerating, aphthous-like lesions, 3-7 mm in diameter, surrounded by a red halo. HFMD is a self-limiting disease in which the lesions heal within one week. Complications like myocarditis are very seldom.
