对北京市１９９０～１９９７年新生儿破伤风（ＮＮＴ）疫情报告的分析表明，１９９０～１９９７年本市户籍ＮＮＴ的发病率为０．０４／１０００活产儿（‰）．１９９７年加上外省户籍病例，ＮＮＴ发病率≤０．１４‰，远低于世界卫生组织提出的发病率为１％的消除水平．本市ＮＮＴ疫情受外省来京人员的影响较大，１９９７年外省户籍病例占全年发病的８４６２％。加强ＮＮＴ疫情监测有重大意义，１９９７年开始将外省户籍病例纳人管理，ＮＮＴ升为乙类传染病进行报告处理，更实际地反映了北京市ＮＮＴ的疫情特点。外省户籍病例均为在家分娩，旧法接生，且放弃治疗的较多，因此加强外省来京育龄期妇女的卫生保健，对高危人群进行破伤风类毒素接种，是本市消除ＮＮＴ的关键。
An analysis of the report of the epidemic of neonatal tetanus (NNT) in Beijing from 1990 to 1997 showed that the incidence of NNT in this Municipality from 1990 to 1997 was 0.04 per 1000 live births (‰). In 1997, with the exception of household registrations in other provinces, the incidence of NNT was ≤0.14 ‰, much lower than the elimination rate of 1% proposed by the World Health Organization. The outbreak of NNT in this municipality was greatly affected by the personnel from other provinces and regions in Beijing. In 1997, the number of household registration cases in other provinces accounted for 8462% of the annual incidence. It is of great significance to strengthen the monitoring of epidemic situation of NNT. In 1997, it began to take administration of household registration of other provinces and NNT to B type of infectious diseases for reporting and treatment, which more effectively reflected the epidemic characteristics of NNT in Beijing. Therefore, strengthening the health care of women of childbearing age in other provinces to vaccinate tetanus toxoid in high-risk groups is the key to the elimination of NNT in this municipality.
