All children aged 7 - 12 years in endemic villages underwent clinical examination, and X-ray examination was performed for clinically positive children. When both the clinical examination and X-ray reexamination were positive, the diagnosis was KBD.Results:In monitoring of 823 365 7 - 12 years old children, a total of 3 057 children with similar clinical signs of KBD were suspected positive cases. The results of X-ray reexamination showed that the X-ray manifestations of 3 057 children were normal, and no X-ray positive changes were found, that is, there was no case of KBD in children. A total of 16 559 endemic villages in 13 endemic provinces were monitored, and all reached the criteria for KBD elimination. Surveillance of all endemic villages was completed except Tibet Autonomous Region, the KBD elimination rates of endemic villages were 100.00% in 12 endemic provinces and 99.01% (16 559/16 725) in all 13 endemic provinces.Conclusions:No children KBD case is detected in 2019, children KBD stays at its eliminating level throughout the country. And 100.00% endemic villages meet the criteria for KBD elimination in the remaining 12 endemic provinces except Tibet Autonomous Region.
