ABSTRACT
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.
