Abstract:
Objective To observe the epidemic trends of Keshan disease (KD) from 1967 to 2012 in Chuxiong City,in order to provide a scientific basis for prevention and control of the disease.Methods The data below was collected and analyzed with epidemiological method.KD cases reported through registration and the death case reported were collected in Chuxiong City from 1960 to 2012,also the reported monitoring results of KD and the adult KD screening results of dilated cardiac patients and mountain patients in 2012 were collected,then epidemic trends of KD was analysed comprehensively.Results There were 1 569 cases of KD registered from 1967 to 2012.There were 566 death cases of KD.The total prevalence rate of KD was 7.7％ (226/2 953) by monitoring children KD at the diseased areas of KD and the potential KD patients accounted for 97.3％ (220/226) from 1990 to 1994.The total prevalence rate of KD was 0.6％ (44/7 174) by surveillance at KD diseased areas from 2005-2012 and the potential KD patients accounted for 70.5％ (31/44),there were 7 children cases of KD under 15 years who accounted for 15.9％ from 2005 to 2012.Totally 313 551 children were given sodium selenium for supplying selenium from 1976 to 2008.Totally 151 cases of KD were found by screening from the patients with dilated cardiac patients since 1988 and they were all chronic KD patients.There were 112 cases of KD in 2012 and there were 6 children cases of KD under 15 years,which accounted for 5.4％.Chuxiong City Keshan disease epidemic presented from subacute Keshan disease to Keshan disease,to latent Keshan disease a slow transition;age from children (＜6 years) to children (＜15 years) to adult-oriented features.Conclusions The incidence and prevalence rate of KD has reached the basic control standards,but children KD is coexisting with adults KD.The pathogenic factors have not been eliminated,disease monitoring and health promotion should be carried out.
