肺炎支原体(MP)是儿童和青少年急性呼吸道感染的常见病因,而肺炎则是MP感染最重要的临床症状。国外文献报告,MP引起的支原体肺炎(又称非典型肺炎)约占普通人群肺炎病例的20%,在密集人群可达总肺炎病例的50%。国内仅有个别普通人群MP感染的报告,尚无关于肺炎病儿MP感染的长期监测报道。为探讨北京地区肺炎儿童的MP感染情况,对肺炎患儿做了血清流行病学调查。现将结果报告如下。 Mycoplasma pneumonia (MP) is a common cause of acute respiratory infections in children and adolescents, and pneumonia is the most important clinical symptom of MP infection. Foreign literature reports, MP caused by mycoplasma pneumonia (also known as atypical pneumonia) accounts for about 20% of the general population of pneumonia cases, in dense populations up to 50% of the total pneumonia cases. Only a few ordinary domestic population MP infection report, there is no long-term monitoring of MP infection in children with pneumonia. In order to explore the MP infection in children with pneumonia in Beijing, a serological epidemiological investigation was performed on children with pneumonia. The results reported below.
