鉴于对当前猩红热的临床和免疫学特点缺乏研究,因此在1980～1981年,作者对猩红热的临床特点进行了研究,而且对比其临床特点和免疫学改变的关系。目前轻型病例占发病率的82.7%,尚未发现特别严重的病例。78.2%的患者经过良好。猩红热的并发症显著减少(仅5～6%)。预后不良的原因主要为并发症,其中最常见的为急性呼吸道病毒感染和咽喉器官的疾患。最近几年继发性猩红热的发病率为7～ In view of the lack of clinical and immunological characteristics of the current scarlet fever, the authors studied the clinical features of scarlet fever from 1980 to 1981 and compared their clinical features with immunological changes. At present, the incidence of light-type cases accounted for 82.7%, no particularly serious cases have been found. 78.2% of patients went well. Scarlet fever complications were significantly reduced (only 5 to 6%). The main cause of poor prognosis is complications, the most common of which is acute respiratory virus infection and diseases of throat organs. The incidence of secondary scarlet fever in recent years is 7 ~
