Abstract:
Objective:To study the current prevalence and temporal patterns of Keshan disease in Gansu Province, thereby establishing a scientific foundation for development of targeted prevention and control strategies.Methods:From March 2019 to October 2021, monitoring of Keshan disease was conducted in all affected townships (towns) across 28 counties (districts, cities) in Gansu Province. Demographic data were collected from affected villages, and suspected chronic Keshan disease cases were identified through village clinics, township health centers, county hospitals, and other medical institutions. These suspected cases were diagnostically verified according to the "Diagnosis of Keshan Disease" (WS/T 210-2011). Current chronic Keshan disease cases underwent re-examination and follow-up monitoring.Results:There were a total of 254 endemic townships (towns) and 2 611 endemic villages across the province, with a permanent resident population of 3.667 1 million in the affected areas. New cases of chronic Keshan disease continued to emerge throughout the study period, totaling 6 cases. From 2020 to 2021, among the total number of chronic Keshan disease cases, 88.92% (923/1 038) remained stable in condition, while mortality cases accounted for 9.54% (99/1 038). Over the past three years, there were 886 males and 687 females with current chronic Keshan disease, mainly aged between 50 and 60 years old, accounting for 38.78% (610/1 573).Conclusions:While Keshan disease in Gansu Province maintains a sustained level of elimination, new chronic cases continue to emerge. It is essential to enhance disease surveillance efforts, and effectively consolidate the achievements in Keshan disease prevention and control measures.
