一起流行性红斑肢痛症爆发的流行病学调查

Investigation on an Epidemic Erythromelalgia

目的 了解1起中小学生流行性红斑肢痛症的爆发流行情况,探讨疾病流行与“厄尔尼诺”和其他类似气候现象的关系。方法 采用流行病学调查分析方法对贵州省遵义县境内2 0 0 4年2～3月发生的中小学生红班肢痛症进行调查。结果 63 5例病人调查中,男生罹患率为3 .10 % (15 9/5 13 3 ) ,女生罹患率为12 .0 7% (4 76/3 943 ) ,差异非常显著(u =16.94,P <0 . 0 1) ;学校地处河边学生罹患率为10 .77% (4 94/4 90 5 ) ;学校不在河边学生罹患率3 .3 8% (14 1/4 171) ,差异非常显著(u =14 .0 5 ,P <0 . 0 1) ;另外,气象资料提示:短期内气温的“V”字形变化,是造成该病流行的促进因素。结论 积极利用气象监测来预报该病的流行趋势工作非常重要。

Objective To investigate an epidemic Erythromel algia among school st udents and explore its relationship with EINino and other climate phenomena. [Methods] Epidemiological analysis was carried out to investigat e the Erythromelal gia attacked in Zunyi during Feb. to Mar. of 2004. [Results] T he morbidity among male students was 3.10% (159/5 133), which among female students was 12.07% (476 /3 943), the difference was greatly significant (u=16.94, P<0.01). The m orbidity in schools near rivers was 10.77% (494/4 905), which of the school not near riv ers was 3.38% (141/4 171), the difference was greatly significant (u=14.05, P< 0. 01). Meanwhile the meteorological data indicated that the short-term V shape c ha nges of temperature were a boosting factor for the prevalence of Erythromelalgia . [Conclusion]It is vital to use meteorological supervision t o predict the prevalence trend of this disease.
