摘要
目的及时了解广东省流行性脑脊髓膜炎(流脑)流行及菌群变化情况,预测发病趋势,为制订与调整预防流脑的策略与措施提供科学依据。方法采用描述流行病学方法。结果广东省2005年共报告流脑105例,发病高峰在2～4月,发病年龄以青壮年为主,发病人群主要为民工或外来打工者,与前5年相比发病年龄高峰后移。健康人群中A群脑膜炎奈瑟菌(Nm)IgG抗体阳性率为78.9%,C群NmIgG抗体阳性率为23.7%,健康人群总带菌率为0.65%。结论将Nm多糖疫苗纳入国家儿童免疫规划管理,流行期间加强对外来流动人口的管理,通过督导等一系列综合措施,提高预防效果及时控制疫情。
Objective In order to know the epidemic situation of Meningococcal Meningitis,and bacterial strain serogroup varies, science basis to adjust the control and prevention strategy and measure was provided. Methods Using descriptive epidemiology to analyze the surveillance data of Meningococcal Meningitis. Results In 2005,105 cases of meningococcal disease are repor ted in Guangdong Province. Most cases （79.05%） occurred among 15-49 years and 51.42% is in floating population. The seasonal peak is between Feb. to Apr. every year. Three outbreaks were identified,including 2 outbreaks caused by serogroup A, 1 by serogroup C. The serogroup A and C IgG positive rates is 78.86% and 23.71% in health population from 856 sero-specimen,and throat swab positive rate in 1 077 cases is 0.65%. Conclusion The local meningococcal cases of Guangdong are sporadic, outbreak serogroup varies is changing. Cases in floating population are rising. Controlling the spread in floating population should be involved in EPI management.
