1989年10月及1990年4月对广州铁路地区2564名5～18岁同批健康儿童青少年进行了两次肺炎支原体(MP)感染的血清流行病学调查。结果表明,该人群秋季MP抗体阳性率为25.59％,GMT为1:4.94;春季分别为4.58％和1:3.54。秋季抗体水平明显高于春季(P<0.05)。提示该地区人群中存在MP感染,应引起重视。
In October 1989 and April 1990, two epidemiological surveys of Mycoplasma pneumoniae (MP) infection were conducted in 2564 young children aged 5-18 in the Guangzhou railroad region. The results showed that the positive rate of MP antibody in autumn was 25.59% and the GMT was 1: 4.94; in spring, it was 4.58% and 1: 3.54, respectively. The level of antibody in autumn was significantly higher than that in spring (P <0.05). Prompted the presence of MP infection in the region should pay attention.
