To describe the epidemiological characteristics and related factors of SARS in Shanxi in order to provide scientific basis for prevention and control of severe acute respiratory syndrome (SARS).
Data on clinically-diagnosed SARS cases reported to Shanxi Center for Disease Control and Prevention through SARS reporting system of Shanxi province and epidemiological reports were collected from early March to 20 May, 2003. The characteristics of SARS distribution in time, place and population in Shanxi were described. The epidemiological characteristics and related influential factors were analyzed with EPI info 6.0 software.
Since the first imported SARS case was diagnosed clinically on 7 March and till 20 May in Shanxi province, the number of cumulative clinically-diagnosed SARS cases were 445 with an attack rate of 1.34/10,000. 20 deaths occurred in that period with the mortality rate 4.49%. The number of cases increased from 28 March and formed the first peak. However, the number continued to increase until 18 April to have formed the second peak. Since then, the number of cases has gradually decreased gradually. Since 19 May, there has been no clinically-diagnosed cases being reported. SARS cases were mostly seen in urban areas of the city (83.82% of the total SARS cases) with sporadic cases found in rural areas. Students and medical staff and people from 20 - 59 years of age occupied the large part of the cases. Age specific mortality rate increased with age and the male/female ratio was 1:0.87.
In Shanxi province, the SARS epidemic seemed to have had the following stages: importation of the first case, gradual increase of the number of cases to reach the peak and decreasing. Case identification at early stage as well as taking measures to decrease the chance of transmission were strategically crucial for controlling the spread of SARS virus in the community.
描述山西省传染性非典型肺炎（SARS）的流行病学特征及相关因素，为严重急性呼吸综合征（SARS）的防控提供科学依据。
收集2003年3月初至5月20日山西省通过SARS疫情报告系统上报至山西省疾病预防控制中心的临床诊断SARS病例资料及流行病学调查报告。描述山西省SARS在时间、地点和人群中的分布特征。应用EPI info 6.0软件对流行病学特征及相关影响因素进行分析。
自3月7日山西省首例输入性SARS临床诊断病例确诊至5月20日，累计临床诊断SARS病例445例，罹患率为1.34/万。期间死亡20例，死亡率为4.49%。病例数自3月28日开始增加并形成第一个高峰，之后继续上升，至4月18日形成第二个高峰，此后病例数逐渐下降。5月19日起，无临床诊断病例报告。SARS病例主要集中在城市市区（占SARS病例总数的83.82%），农村地区有散发病例。学生、医务人员及20～59岁人群占病例的大部分。年龄别死亡率随年龄增加而上升，男女性别比为1:0.87。
山西省SARS疫情呈现首例输入、病例数逐渐增多至高峰然后下降的过程。早期病例识别以及采取措施减少传播机会对于控制SARS病毒在社区的传播至关重要。
