Abstract:
Objective To investigate the prevalence and incidence of Keshan disease (KD) and the selenium concentration of food and hair in residents of Yongjin Village, Fuyu County, Heilongjiang Province, national monitoring site, in 2007. Methods According to the Standard of Keshan Disease Surveillance and the Standard of Diagnosis of Keshan Disease(GB 17021-1997), the residents living in the monitoring site were surveyed by clinical examination and electrocardiography. For individuals whose hearts showed abnormalities, a chest X-ray photograph was taken. The selenium concentrations of the residents' food (flour) and hair were assayed by flowing injection hydride generation atomic fluoremetric method(FI-HG-AFM). Results Nineteen KD patients were found from 282 residents in 2007 KD surveillance. The prevalence of KD, latent KD and chronic KD were 6.7%(19/282), 2.8%(8/282) and 3.9%(11/282), respectively. Five of the 8 latent KD cases were newly found. In addition, there were 5 the suspected KD cases, including 2 suspected chronic KD cases. No acute KD or sub-acute KD patients were found in Yongjin Village at this monitoring site this year. The average selenium concentration of children hair and residents food were (0.3197±0.0586)mg/kg and (0.0210±0.0062)mg/kg, respectively. Conclusions New cases of KD continued to emerge, indicating that etiological factors still exist. Therefore, the emphasis of monitoring KD in furore is founding the consummate report of infectious disease system and training the personnel to increase the reliability of monitoring.
