Abstract:
Objective:To learn about the current situation and growth and decline trend of Keshan disease in Gansu Province, so as to provide scientific basis for key prevention and control of Keshan disease.Methods:In 2019, the cross-sectional survey method was used to carry out case search in all diseased townships (towns) in 28 diseased counties (districts) of Gansu Province. The situation data of the disease areas were collected under the jurisdiction of counties (districts), and suspected cardiomyopathy cases were investigated by village doctors in the whole township (town) with the village as the unit. Suspected cases were diagnosed according to "Diagnosis of Keshan Disease" (WS/T 210-2011).Results:No Keshan disease cases were detected in the disease affected 8 counties (districts) of Gansu Province, and chronic and latent Keshan disease cases were detected in the remaining 20 counties (districts), and no cases of acute or subacute Keshan disease were found. There were 668 cases of Keshan disease, including 509 cases of chronic Keshan disease, 159 cases of latent Keshan disease; and 1 new case of chronic Keshan disease was found, the annual incidence rate was 0.10/10 000 (1/96 449). The specific ratios of male and female patients were 1.33 ∶ 1.00 (291 ∶ 218) and 1.01 ∶ 1.00 (80 ∶ 79) in chronic and latent Keshan disease; the age of chronic and latent Keshan disease was mainly > 50 - 60 years old, accounting for 36.94% (188/509) and 42.14% (67/159), respectively, followed by the > 60 - 70 years old, accounting for 36.15% (184/509) and 25.79% (41/159), respectively.Conclusion:Keshan disease is in a stable low incidence situation in Gansu Province, but there are still new cases, so the continuity of disease monitoring should be maintained.
