Four school children, aged 6 to 9 years, had acute postinfectious myositis. The prodromal illness usually involved the upper respiratory tract, but gastrointestinal symptoms were also seen. Fever and nonspecific malaise were characteristic. After cessation of the illness, myalgia involved the calves and thighs. Arm and neck muscles were less frequently affected. Weakness was less marked than muscle pain. Serum creatine phosphokinase (CPK) was markedly increased in all cases. Myalgia and CPK levels subsided in less than a week, although one child was not back to normal for 4 weeks. Two children had electromyography, and patchy myopathic changes were found. Viral studies were not helpful in any of the cases.
四名6至9岁的学童患有急性感染后肌炎。前驱疾病通常累及上呼吸道，但也可见胃肠道症状。发热和非特异性不适为其特征。疾病结束后，肌痛累及小腿和大腿。手臂和颈部肌肉较少受累。无力症状不如肌肉疼痛明显。所有病例血清肌酸磷酸激酶（CPK）均显著升高。肌痛和CPK水平在不到一周的时间内消退，尽管有一名儿童4周后才恢复正常。两名儿童进行了肌电图检查，发现有散在的肌病改变。病毒学研究对任何病例均无帮助。
