A descriptive spatial epidemiological study on prevention and control of Keshan disease in China / 中华地方病学杂志

ABSTRACT

Objective To explore the spatial description of Keshan disease(KD)and to provide a basis for reasonable allocation of health resources and for making precision prevention and control strategies. Methods In 2013 and 2014, the KD's condition, prevention and control measures and their effects were investigated in the diseased affected counties in the provinces through combination of case search and key survey. Results A total of 16(100.0%,16/16)diseased provinces,315(96.0%,315/328)diseased counties were surveyed,and 1 562 people with KD were detected in 281 000 residents, the detection rate was 55.6/10 000. Chronic and latent KD detection rates were 8.9/10 000(250)and 46.7/10 000(1 312),respectively.There were 261(82.9%)diseased counties that had reached the control standards of KD,and 54(17.1%)did not meet the control standards,which mainly distributed in the provinces of Henan, Inner Mongolia, Gansu and Shanxi. Conclusions The detection rate of KD has been at a low level, but in Henan, Inner Mongolia, Gansu, and Shanxi, there are prevalent KD areas that have not yet reached the control level.This part of the areas should be treated as key prevention and control areas of KD.
