目的 阐明本地区中小学生风湿热（ｒｈｅｕｍａｔｉｃ ｆｅｖｅｒ，ＲＦ）和风湿性心脏（ｒｈｅｕｍａｔｉｃ ｈｅａｒｔ ｄｉｓｅａｓｅ，ＲＨＤ）的流行趋势，并探讨其防治对策，为有关部门提供指导。方法 按照全国协作组统一制订的方案，采用整群抽样方法，发当今国际上公认的Ｊｏｎｅｓ标准，对城乡４５６１６名中小学生，连续３年进行ＲＦ和ＲＨＤ的监测研究。结果 研究对象ＲＦ年平均发病率（１／１０万）城市组为１４．

Objective To explore prevalence trend of rheumatic fever(RH) and rheumatic heart disease(RHD) in juvenile, and to discuss its prevention strategies.Method A surveillance and follow-up study on RFnd RHD was made in 45 616 juveniles for three years continuously,based upon the unified program drew by national cooperative group and Jones standards generally recognized,and by applying cluster sampling method. Results RF incidence every year is 14.3(1/100 000)in urban group,15. 11 in rural group. RHD detectable rate is 0.22% and 0. 18‰ respectively,α-streptococcus car rier rate is 5.50% ~ 18.80% ed 9.20% ~ 48. 10% separately in defferent seasons.The prevalence of RE and RHD demonstrates significant differences between urban and rural and rural groups,which is associated with sex,age and other liable fac tors.Conclusion Careful observation should be paid to RF and RHD epidemic trends,the emphasis in its early preventive measure is upon rural school-aeg children.
