目的了解广西流脑流行特征的动态变化,预测流脑发病趋势,为制定合理防制措施提供依据。方法在2006年全年对广西各市、县进行面上的监测。选择凭祥市、全州县和大化县作为流脑重点监测点在流行前期进行健康人群带菌及抗体水平调查。结果2006年广西流脑发病率为0.094/10万,部分人群的Nm带菌率为1.15%,A群抗体阳性率为29.9%,C群抗体阳性率为21.7%。结论2006年广西流脑发病率不高,病死率较高,监测点人群对A群流脑有一定抵抗力,而对C群流脑的免疫力较低,流脑仍然是广西人民特别是青少年儿童健康的重要威胁。
Objective To understand the dynamic changes of epidemic characteristics of meningococci in Guangxi and predict the trend of the incidence of meningococci, so as to provide the basis for making rational prevention and control measures. Methods In 2006, the monitoring of Guangxi’s cities and counties was conducted. Pingxiang City, Quanzhou County and Dahua County were selected as the focus of Moxibustion monitoring point in the pre-epidemic of healthy population and antibody levels survey. Results The incidence of meningitis in Guangxi was 0.094 / 100000 in 2006, and the prevalence of Nm in some population was 1.15%. The positive rate of antibody in group A was 29.9% and the positive rate of antibody in group C was 21.7%. Conclusion The incidence of meningitis in Guangxi was not high and the case fatality rate was high in 2006. The surveillance group showed some resistance to group A meningitis and low immunity to group C meningitis. The meningococcal meningitis is still a serious problem for Guangxi people, especially adolescents An important threat to children’s health.
