探讨一起学校肺炎支原体暴发疫情的流行传播特征。采集标本检测肺炎支原体核酸与抗体,应用现场流行病学调查方法分析疫情。该校共计发病21例,学校罹患率31.91%(15/47),家庭续发率33.33%(6/18),患者咽拭子标本肺炎支原体核酸阳性,患者肺炎支原体抗体为(41.50±6.93)ng/L,未发病者(35.11±1.41)ng/L,二者差异无统计学意义(t=2.03,P=0.48)。首例病例未采取隔离引起暴发,早期做好呼吸道隔离,预防交叉感染极其重要。
Explore the epidemiological characteristics of mycoplasma pneumoniae outbreaks in schools. Samples were collected for detection of Mycoplasma pneumoniae nucleic acid and antibodies, epidemiological analysis of the epidemic situation using on-site epidemiological methods. The total incidence of the disease was 21.91% (15/47) in the school and 33.33% (6/18) in the family. The throat swab specimens were positive for Mycoplasma pneumoniae, and the mycoplasma pneumoniae antibody was (41.50 ± 6.93) (35.11 ± 1.41) ng / L, there was no significant difference between the two groups (t = 2.03, P = 0.48). The first case did not take isolation caused by outbreaks, good early respiratory isolation, prevention of cross-infection is extremely important.
