为了解丹东地区肺吸虫宿主感染情况和人群肺吸虫病感染率、患病率的动态变化 ,探讨肺吸虫病发病规律和流行特点 ,采用回顾性调查方法 ,对 196 3～ 1998年丹东地区肺吸虫病流行和防治资料进行分析。结果显示 ,宿主川卷螺感染率由 196 4年的 2 .2 0‰下降至 1993年的 0 .6 7‰ ,1994年后螺密度锐减 ,很难采集到。 196 4年东北喇蛄感染率均在 6 0 %以上 ,感染度无明显变化 ,1996年后疫河中喇蛄几乎绝迹。家犬感染率在 44 .11%左右 ,剖检家犬阳性率在 84%以上 ,平均每犬得虫数为 34.85只。人群肺吸虫病感染率由 1991年的 2 3.36 %下降至 1998年的15 .2 4%。肺吸虫病发病率由 196 3年的 12 .9%下降至 1991年的 0 .4%。 1998年暴发流行传入性肺吸虫病 ,发病率92 .2 %。因此 ,丹东地区卫氏肺吸虫病基本控制。但传入性肺吸虫病尚难以控制。今后防治工作应在严密监测加强宣教的同时 ,加强境外河蟹的检疫及监测传入性肺吸虫病的疫情变化 ,防止其发生和流行 To understand the infection status of paragonimiasis and the prevalence and prevalence of paragonimiasis in Dandong, and to explore the prevalence and prevalence of paragonimiasis, the retrospective investigation method was used to analyze the prevalence of paragonimiasis in Dandong from 196 3 to 1998 Epidemics and prevention data were analyzed. The results showed that the infection rate of the host Chrysosporium decreased from 2.20 ‰ in 196 4 to 0.667 ‰ in 1993, and declined sharply after 1994, making it difficult to collect. In 1964, the infection rates of Laodendron in northeastern China were above 60%, with no significant change in infection rate. Dog infection rate was about 44.11%, the positive rate of autopsy dogs was more than 84%, the average number of dogs per dog was 34.85. The prevalence of paragonimiasis in the population declined from 2336% in 1991 to 15.24% in 1998. The incidence of paragonimiasis dropped from 12.9% in 1996 to 0.4% in 1991. Outbreak of imported paragonimiasis in 1998, the incidence rate of 92.2%. Therefore, the basic control of paragonimiasis paragonimiasis in Dandong area. However, the introduction of paragonimiasis is still difficult to control. In the future, prevention and control work should be closely monitored and strengthened; at the same time, quarantine of overseas crabs and monitoring of epidemic changes of imported paragonimiasis should be strengthened so as to prevent their occurrence and prevalence
