Abstract
ObjectiveTo investigate the dynamic prevalence of Kashin-Beck disease (KBD) in 2020, and to provide the basis for assessment of KBD control and elimination.
MethodsAccording to the "Kashin-Beck Disease Monitoring Plan (2019 Edition)", collection of basic information of endemic areas and children KBD examination were executed in all endemic areas from every endemic county (city, district, banner) of 13 endemic provinces. All children aged 7 - 12 years in endemic areas underwent clinical examination, X-ray examination was performed for clinically positive children. According to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), KBD cases were diagnosed by both clinical examination and X-ray check.
ResultsIn monitoring of 827 986 children of 7 - 12 years old, a total of 703 children with similar clinical signs of KBD were suspected positive cases. X-ray results showed that 703 children were normal, with no X-ray positive change, they were not children KBD cases.
ConclusionsIn 2020, no cases of Kashin-Beck disease are detected in children nationwide, and the condition of Kashin-Beck disease in children nationwide continues to be at a level of elimination.
