北京地区肺炎支原体肺炎的流行状况

目的了解北京地区肺炎支原体(MP)肺炎的发病规律及感染后带菌状况。方法选择1929例儿科住院的肺炎患儿,对不同年度、不同季节、不同年龄MP肺炎的发病情况进行统计。对20例确诊为MP肺炎患儿进行随访。结果MP肺炎发病率第一、二、三季度间比较P均>0.05,第一、二、三季度分别与第四季度比较,P均<0.05。7~9岁与10~14岁比较P>0.05,1个月~3岁与4~6岁、7~9岁、10~14岁比较,4~6岁与7~9岁、10~14岁比较P均<0.05。1992~1994年支原体肺炎呈逐年下降趋势,而1995年末发病显著增加(2、3倍),后又有下降趋势。20例MP肺炎培养结果显示,带菌时间最短为0.5个月,平均带菌时间为1.5个月,最长为4.5个月。结论MP肺炎的发病与年龄、季节和年度有密切关系。

Study of Epidemic Regulation of Mycoplasmal Pneumonia in Beijing

Objective To understand the epidemic regulation of mycoplasmal pneumonia in Beijing and the carriageable time of mycoplasma pneumonia (MP) after affecting mycoplasmal pneumonia.Methods The data of 1929 inpatients with mycoplasmal pneumonia in the department of pediatrics were statisted. And the incidences in different quarters, ages and years were analyzed. Twenty patients with mycoplasmal pneumonia were treated.Results There were no difference of discrepancy in the first quarter, the second and the third,all P>0.05. The first quarter, the second, the third respectively compared with the fourth, all P<0.05. Six to nine years old compared with 9-14 years old, P>0.05. One month to 3 years old compared with 4-6 years old, 7-9 years old, 10-14 years old, all P<0.05.Four to six years old compared with 7-9 years old, 10-14 years old, P<0.05.The incidence declined gradually in 1992-1994. The incidence was the highest in 1995. The shortest carriageabe time of MP was a half month.The average carriageabe time of MP was one and half months. The longest carriageabe time of MP was four and half months. Conclusions The incidence of MP was closely related to season,age and year.The carriageabe time of MP after the onset differed with different patients,and the correlation factors should be further studied.
