目的探讨地震灾害对克山病流行的潜在影响,为指导防治提供科学依据。方法采用现场流行病学方法,评估防治能力、发病危险性、人群硒营养水平和硒干预措施。结果克山病致病因素依然存在且致病力强并活跃;近1/3的人群缺硒;合格硒盐的覆盖率为24.5%;防治机构和仪器损毁严重。结论地震灾区存在克山病流行的潜在危险,应建立健全克山病防治的长效机制。
Objective To investigate the potential impact of earthquake disaster on Keshan disease and provide a scientific basis for prevention and control. Methods Epidemiological methods were used to evaluate the prevention and treatment, risk of onset, selenium nutrition and selenium intervention in the population. Results The pathogenic factors of Keshan disease still existed and the pathogenicity was strong and active. Nearly 1/3 of the population was selenium-deficient. The coverage rate of qualified selenium salt was 24.5%. The prevention and cure institutions and equipment were seriously damaged. Conclusion There is a potential risk of Keshan disease in the quake-stricken area and a long-term mechanism should be established to improve the prevention and treatment of Keshan disease.
