目的了解广州市萝岗区C群流行性脑脊髓膜炎抗体水平。方法 2013年采取分层随机抽样的方法采集萝岗区8个不同龄组健康人群血清学进行抗体检测。结果萝岗区C群流行性脑脊髓膜炎血清杀菌抗体阳性率为60.30%(161/267),保护率为55.43%(148/267)。7~14岁最高,抗体阳性率和保护率高达94.59%和89.19%,其次是3~6岁,抗体阳性率和保护率均为75.32%,3岁以下儿童抗体阳性率和保护率最低,仅有26.23%和22.95%。结论萝岗区C群流行性脑脊髓膜炎抗体水平仍达不到防控要求;3岁以下散居儿童是C群流行性脑脊髓膜炎防控的重点人群。
Objective To understand the antibody level of epidemic cerebrospinal meningitis in group C of Luogang District of Guangzhou City. Methods In 2013, stratified random sampling method was used to collect serological samples from 8 different age groups in Luogang District for antibody detection. Results The positive rate of serological bactericidal antibodies against epidemic cerebrospinal meningitis in group C of Luogang District was 60.30% (161/267) and the protective rate was 55.43% (148/267). The highest positive rates of antibody and protection were 94.59% and 89.19%, followed by those aged 3-6 years. The positive rates and the protection rates of antibodies were all 75.32%. The antibody positive rates and protection rates of children under 3 years old were the lowest There are 26.23% and 22.95%. Conclusion The antibody level of epidemic cerebrospinal meningitis group C in Luogang District still can not reach the level of prevention and control. Diarrhea children under 3 years old are the key population for prevention and control of epidemic cerebrospinal meningitis in group C.
