Objective To observe the trends of prevalence and incidence of Keshan disease(KD) in China from 2000 to 2004. Methods Based on the Standard of Keshan Disease Surveillance(WS/T 78-1996) and the Standard of Diagnosis of Keshan Disease(GB 17021-1997),the residents in the surveillance sites were surveyed. Some factors potentially contributing to KD were also investigated. Results The average prevalence of latent and chronic KD was 3.8% and 0.8% respectively, and the estimated Keshan disease patients were up to 5.7 to 6.22 millions, among whom, 960 thousands to 1.18 millions were chronic KD patients. In the five years, 113 new cases of latent KD patients and 29 new cases of chronic KD patients were found at the surveillance sites. The level of hair selenium of the people surveyed was 0.305 mg/kg. The level of food selenium surveyed was 0.017 mg/kg. Conclusions The prevalence of KD in part of KD areas are not clear. The level of food selenium is still low. New cases of KD were still found. KD is therefore one of the seriously endemic public health issues. Surveillance and management of chronic KD patients, should be emphasized.
