Abstract:
Objective:To master the new cases and the condition of Keshan disease (KD) in key endemic areas and provide scientific basis for updating control strategies.Methods:In 2017, sentinel surveillance was carried out in some counties with substandard KD or serious historical KD. Two to three villages with more KD patients and the total population of 1 000 were chosen to investigate. All of the inhabitants were checked by physical examination and electrocardiography. Suspected KD patients were examined by echocardiography. KD was identified according to "Diagnosis of Keshan Disease" (WS/T 210-2011). The confirmed cases were followed up.Results:A total of 70 008 people were examined in 86 counties of 14 provinces. The ratio of male to female was 1.0 ∶ 1.2 (31 720/38 288). The total number of KD patients identified was 308, including 68 chronic KD and 240 latent KD. The detection rates were 44/10 000, 10/10 000 and 34/10 000, respectively. Totally 198 cases of chronic KD and 115 cases of latent KD were followed up, and the follow-up mortality was 8.1% (16/198) and 7.0% (8/115), respectively. In this year, 29 cases of latent KD and 5 cases of chronic KD were newly diagnosed.Conclusion:There are still a number of KD patients including new cases in endemic areas with high prevalence nowadays or in the past indicating the prevention and control of KD should be maintained.
