ABSTRACT
Objective In order to accumulate data for the final evaluation and acceptance of the Twelfth Five-Year Plan of National Endemic Disease Prevention and Control,we investigated the endemic scopes and basic situation of Keshan disease (KD) in Harbin.Methods According to the Criteria for Diagnosis of Keshan Disease (WS/T 210-2011),we conducted clinical survey of KD prevalence in 10 KD endemic counties in Harbin in 2013.2011-2015,we detected and searched for cases in 10 ward counties of Keshan disease.According to the Delimitation and Classification of Keshan Disease Areas and the Evaluation of Endemic Disease Control and Elimination,we determined the regional type,the situation of control and elimination of the disease,at the same time all KD patients were positioned by global positioning system (GPS).Results There were 2 KD endemic counties,12 endemic townships,and 37 KD patients in Harbin.All 12 townships were the light endemic regions of KD.Other townships were conformed to be the history regions with KD.The management index scores of KD reached the elimination requirements which were more than 85 points in every region county (city).Ten region counties got to technical standards for KD elimination.Harbin basically reached the index of KD elimination.The GPS satellite positioning of KD patients were concentrated in the 45.1-45.5 degrees north latitude,and 127.7-128.3 degrees east longitude.Conclusion The regions of KD endemic areas have narrowed down and the prevalence rate has declined significantly in Harbin,which have reached the basic elimination standards of KD by the 12th Five-Year Plan.
