目的了解丹江口库区肺吸虫病的流行现状。方法调查库区丹江口市自然环境变化和移民情况,并对溪蟹的肺吸虫囊蚴携带率进行流行病学调查,应用肺吸虫抗原IDT和ELISA检测易感人群。结果丹江口库区的环境有利于中间宿主溪蟹的繁殖、扩散,而淹没区的移民将使人口分布更趋集中。人群的肺吸虫抗原皮试(IDT)和ELISA的阳性率分别为8.09%和7.96%,当地溪蟹的肺吸虫囊蚴携带率为5.35%。结论丹江口库区环境、人口的变化及居民有生食和半生食溪蟹的习惯,将可能导致肺吸虫病的流行和扩散,应加强肺吸虫病防治知识的宣传和教育,制定相应的防治措施,防止肺吸虫病在库区的流行。
Objective To understand the prevalence of paragonimiasis in Danjiangkou reservoir area. Methods The changes of natural environment and immigration of Danjiangkou in the reservoir area were investigated. The carrying rate of Paragonimus sibirica in crabs was investigated by epidemiological investigation. The susceptible population was detected by IDT and ELISA. Results The environment in Danjiangkou reservoir area is conducive to the reproduction and spread of crabs and crabs, while the immigrants in inundated areas will make the population more concentrated. The prevalence of paragonimiasis antigen skin test (IDT) and ELISA in populations was 8.09% and 7.96% respectively, while that of local crabs was 5.35%. Conclusion The changes of environment and population in Danjiangkou reservoir area and the habits of residents living crabs and raw crabs may lead to the spread and spread of paragonimiasis. Publicity and education on paragonimiasis prevention should be strengthened and relevant prevention and control measures should be formulated. Prevention of paragonimiasis epidemic in the reservoir area.
