Abstract:

目的分析四川省传染性非典型肺炎[严重急性呼吸综合征(SARS)]的流行病学特点。方法运用描述流行病学的方法,收集、整理、汇总四川省SARS病例资料,分析疫情的三间分布、来源和病例发现方式、临床症状及诊疗情况。结果2003年4月16日至5月7日是四川省SARS疫情发生的高峰,其中泸州市和广元市病例数占全省病例总数的60%,病例中民工占68%;20～岁年龄组发病人数最多,男女发病之比为1.5∶1;80%的病例来源于广东省。患者症状以发热、咳嗽为主,X线胸片有阴影。结论四川省SARS病例均为输入性,人员流动(特别是外出务工人员返乡)是影响疫情波动的主要因素。对此采取以隔离传染源为主导措施(设立留验站、定点医院、发热门诊等)的防制方法,有效控制了疫情。

English Abstract:

Objective To explore the epidemiological characters of severe acute respiratory syndrome (SARS) in Sichuan province in order to provide evidence for prevention and control.Methods To generate data on SARS in Sichuan province through descriptive and analytical studies on time, geographic distribution, population, source of infection, the way of case finding, symptom, diagnosis and treatment of the cases.Results The peak of the epidemic last from April 16 to May 7. The number of cases in Luzhou and Guangyuan cities took up 60% of the total. Mobile population occupied 68% of the cases. Most of the patients were above the age of 20 with a sex ratio of 1.5∶1(m/f). 80% of the cases had a history of working in Guangdong province and recently returned to their hometowns. The main symptoms and signs of the SARS patients would include fever,cough and chest X-ray changes. Conclusions All cases were imported. Fluctuation of the epidemics was mainly affected by the mobility of working population who recently returned to their hometowns. Measures concerning the prevention and control of the epidemics would mainly target on the isolation of confirmed and suspected patients who might serve as the sources of infection through setting up quarantine station, assigned hospitals and special 'fever-clinics'.
