目的 :分析 SARS临床诊断病例和疑似病例的流行病学特征和临床特征及其相关性 ,评价流行期间 SARS的早期诊断工作。方法 :对 2 0 0 3年 3月 1 5日到 5月 1 4日某地 SARS临床诊断病例 (1 5 5 0例 )和疑似病例 (790例 )的相关特征进行描述和对比 ,通过分析存在的异同以及可能的原因来评价 SARS早期诊断情况。 结果 :90 %左右的病例在发病后 6 d内做了诊断。临床诊断病例和疑似病例在发病时间 (r=0 .94 1 )、地区分布 (r=0 .793)及年龄 (r=0 .96 1 )和职业构成 (r=0 .937)等方面存在显著的相关关系 ;同样情况也见于临床症状 (r=0 .996 )、白细胞 (正常时 r=0 .72 3,降低时 r=0 .86 3)及淋巴细胞 (正常时r= 0 .772 )等指标。 结论 :SARS临床诊断病例和疑似病例在多数特征上存在相似性 ,应开发特异性的早期诊断方法
OBJECTIVE: To analyze the epidemiological and clinical features and their correlation of clinical diagnosis and suspected SARS cases and to evaluate the early diagnosis of SARS during the epidemic. Methods: The clinical features of SARS cases (1550 cases) and suspected cases (790 cases) in a certain place from March 15 to May 14, 2003 were described and compared. Similarities and differences and the possible reasons to evaluate the early diagnosis of SARS. Results: About 90% of cases were diagnosed within 6 days after onset. Clinical diagnosis and suspected cases were found in terms of time of onset (r = 0.94 1), geographical distribution (r = 0.793), age (r = 0.96 1) and occupational composition (r = 0.937) (R = 0.996), white blood cells (r = 0.72 3 at normal time, r = 0.86 3 at time of decrease) and lymphocytes (r = 0.772 at normal time ) And other indicators. CONCLUSIONS: There are similarities in most of the clinical features and suspected cases of SARS, and specific early diagnosis should be developed
