为了准确地掌握江滩型重疫区血吸虫病疫情动态和趋势,应用流行病学原理和方法,对流坡村系统观测六年。经三年人群扩大化疗后人群感染率曾一度下降,但很快回升,急性感染人数减少,但仍有发生;滩地螺情一直较重,感染螺消长与水情相关;据调查,该试区主要传染源为感染的牛和猪。观测结果提示,人群扩大化疗对江滩型重疫区虽能降低人群感染率,但难以阻断血吸虫病传播。为控制疾病,当前仍需坚持人畜同步扩大化疗,同时,要积极探讨人群再感染规律及影响因素,以便不断完善防治策略。
In order to accurately grasp the epidemic situation and trend of schistosomiasis in the severe flooding area of river beach, epidemiological principles and methods were used to observe the system of the slope slope village for six years. After three years of population expansion after chemotherapy, the infection rate of the population decreased once, but quickly recovered, but the number of acute infections decreased. However, the incidence of infection still persisted. The main source of infection is infected cattle and pigs. Observations suggest that population expansion of chemotherapy in Jiangtan type heavy endemic area can reduce the population infection rate, but difficult to block the spread of schistosomiasis. In order to control the disease, it is still necessary to stick to the simultaneous extension of chemotherapy between humans and animals. At the same time, we must actively explore the rules and influencing factors of population re-infection in order to continuously improve the prevention and control strategies.
