SARS流行的科学防治需要基于SARS流行特点 ,以便采取有效的措施。经对北京市丰台区的 1 656名SARS密切接触人员的追踪调查。通过队列研究 :与家人亲戚队列 (组 )相比 ,医院内暴露队列的比值比 (Oddsratio)为 62 5倍 (P <0 0 0 1 ) ,夫妻组队列的比值比为 8 35倍 (P =0 0 9) ,民工工地队列的比值比 5 55倍 (P =0 1 4 6)。因此 ,影响发病因素主要是暴露强度 ,与年龄、性别无关。建议主要应控制医院内的暴露 (院内传染 ) ,类似夫妻关系的密切接触暴露 ,民工工地的暴露。
The scientific control of SARS epidemic needs to be based on the SARS epidemic in order to take effective measures. Follow-up survey of 1 656 close contacts of SARS workers in Fengtai District of Beijing. In a cohort study, odds ratio was 62 5 times (P <0.01) in hospital cohorts and 8 35 times in cohort cohorts (P = 0 0 9), the ratio of migrant workers to field cohort was 555 times (P = 0 1 46). Therefore, the main factors affecting the incidence of exposure intensity, and age, gender has nothing to do. The recommendations should mainly control hospital exposure (nosocomial infections), exposure to similar husband-wife contacts, and exposure to migrant workers.
