2007年云南省克山病监测报告

目的 掌握云南省克山病病情,为克山病防治工作提供科学依据.方法 2007年按照克山病病情监测方案的要求,根据历史病情,在云南省选择11个县(市)中的16个病村作为监测点,对监测点居民进行普查.详细询问病史、临床体检、描记心电图;对克山病病人及可疑病例拍摄2 m后前位X线胸片,按<克山病诊断标准>(GB 17021-1997)进行诊断.全省的克山病病情资料,由2007年的克山病病情报告、线索调查结果等汇总而成.结果 16个监测点共检诊6877人,共检出克山病病人39例,总检出率为0.57%(39/6877).其中潜在型克山病检出率为0.41%(28/6877);慢型克出病检出率为0.16%(11/6877);急型及亚急型克山病未检出.66.67%(26/39)克山病病人集中在5～14岁.16个监测点共描记心电图6877份,心电图异常率为5.25%(361/6877);共拍摄了55例X线胸片,心胸比例≤0.50的31例,0.51～0.55的16例,0.56～0.60的8例.云南省慢型克山病患病率为4.24/10万,发病率为0.50/10万,无急型及亚急型克山病发生,潜在型克山病未列入克山病病情报告内容.16个监测点慢型克山病患病率为7.76/10万,发病率为1.18/10万.结论 云南省克山病处于平稳低发状态,但部分地区慢型克山病检出率较高,应进行有针对性的防治工作.

Analysis of Keshan Disease surveillance data in Yunnan Province in 2007

Objective To study the current incidence of Keshan disease in Yunnan Province,and provide scientific basis for Keshan disease(KD) prevention and control. Methods Based on the Scheme of KD Surveillance, 16 villages in 11 counties were chosen as surveillance sites by the historical data. An survey was made to the residents in the 16 surveillance sites by filling in the questionnaire, inquiry medical history, clinical examination, electrocardiogram and 2 meters post-anterior chest X-ray for suspected cases. KD cases were diagnosed according to the Diagnostic Criteria for Keshan Disease(GB 17021-1997). The prevalence data of KD in the whole province were collected from the KD case report in 2007 and the trace surveys. Results There were 6877 residents in 16 surveillance sites of 11 surveillance counties and totally 39 KD cases were diagnosed with a detection ratio of 0.57% (39/6877). The detection ratio of latent and chronic KD were 0.41%(28/6877) and 0.16%(11/6877), respectively and no acute or subacute cases were found. The cases aged 5 to 14 years old accounting for 66.67% (26/39). Electrocardiogram examination of 6877 residents were made and 5.25% (361/6877) abnormal electrocardiograms were detected in the 16 surveillance sites. Fifty-five people were checked by chest X-ray and there were 31 cases with heart-chest ratio ≤0.50, 16 cases with heart-chest ratio from 0.51 to 0.55 and 8 cases with heart-chest ratio from 0.56 to 0.60. The prevalence rate and incidence rate of chronic KD were 4.24 per 100 000 and 0.50 per 100 000 in Yunnan. No acute or subacute cases were found and the latent cases were listed. The prevalence rate and incidence rate were 7.76 per 100 000 and 1.18 per 100 000 in the 16 surveillance sites. Conclusions The incidence of KD is low incidence in Yunnan Province. Higher ineidence of chronic KD was detected in the some areas and the corresponding control measures need to be adopted.
