本文对柘城县三年来流脑监测工作作了初步分析,认为流脑多糖体菌苗对15岁以下儿童普种,是目前予防流脑的有效措施,能大面积降低流脑发病率,死亡率和 A 群带菌率,但季节性发病高峰没有改变。普种后发病年龄高移值得注意。人群总带菌率的高低与流脑发病无关,而 A 群带菌率的高低与发病有关。推带 A 群 NM 菌也可产生抗体。从带菌调查和抗体水平测定结果初步提示,人群 A 群 NM 带菌率在5%以上,A 群抗体阳性率在70%以下,GMT 在5以下可作为流脑发生流行的予测指标。 This article made a preliminary analysis of the epidemiological surveillance in Yuncheng County in the past three years and concluded that the meningitis cerebrospinal fluid vaccine is common to all children under 15 years of age and is an effective measure to prevent it. It can greatly reduce the incidence of meningococcal disease and death Rate and group A colonization rate, but the seasonal peak did not change. After the general high incidence of age shift worth attention. The total population carrying rate of the population has nothing to do with the incidence of meningitis, while the rate of infection with group A is related to the incidence. Push group A NM bacteria can also produce antibodies. From the results of the carriage investigation and the antibody test, the results showed that the prevalence of NM in the group A was above 5%, that of the group A was below 70%, and the GMT below 5 could be used as the predictor of the prevalence of meningococci.
