绵竹地震灾民集中安置点健康人群脑膜炎奈瑟菌带菌率调查

Carrying Rate of Neissria Meningitides in a Healthy Population in the Mianzhu Post-earthquake Residential Area

目的了解汶川大地震后绵竹灾民集中安置点流行性脑膜炎奈瑟菌(Neisseria meningitides,Nm)带菌状况,为预测疫情和制定防治措施提供依据。方法对绵竹灾区二号桥灾民集中安置点和体育场灾民集中安置点进行单纯随机抽样,采取咽拭子样品887份,采用TaqMan-MGB探针RT-PCR技术以及试剂盒RT-PCR法进行检测。结果887份咽拭子检出3例阳性。结论灾区与四川省及全国其它地区往年带菌率相比流脑带菌率较低,发生流脑疫情的可能性不大,说明灾后卫生防疫等相关部实施的防御措施积极有效,但针对灾区实际环境,进一步的卫生防疫工作不可懈怠。

Objective To predict the possibility of epidemic outbreak of meningitis by testing Neissria Meningitides in a healthy population in the Mianzhu post-earthquake residential area. Methods A simple random sampling strategy was adopted to collect 887 throat swabs from a healthy population in the Mainzhu post-earthquake residential area. The TaqMan assay were performed to detect Neissria Meningitides. Results Three positive samples were identified. Conclusion The carrying rate of Neissria Meningitides is not high enough to bring about an epidemic outbreak of Meningitis. However, efforts to maintain a hygienic environment in the post-earthquake residential area should be continued.
