目的了解地震灾后疫区黑热病流行趋势,为制定灾后黑热病防治对策提供依据。方法收集、核实和处理网络直报疫情报告和各级医疗卫生机构病历资料;了解各受灾疫区防治措施实施情况。结果各疫区地震前每年不同程度地开展了各种防治措施,发病数有所下降,但仍在高位徘徊;地震当年采取较大范围的灭犬措施和在人群集居地反复使用杀虫剂,病例数较往年有所减少;地震后次年,由于防治工作的松懈,发病数较地震当年有所增加。结论地震使疫区的生态环境、人居环境等发生了很大变化,灾后疫区传染源、传播媒介、易感人群和自然与社会因素依然存在,其暴发和流行的风险犹存,仍需做好灭犬、灭蛉工作,加强对黑热病的询诊和监测,开展利什曼原虫感染犬的查杀和防治黑热病知识宣传,在灾后一段时间里,黑热病发生的风险可以控制在一定范围内。 Objective To understand the epidemic trend of kala-azar in the post-quake-affected areas and provide evidence for the prevention and control of kala-azar in post-quake-hit areas. Methods Collecting, verifying and processing network reports of epidemic situation reports and medical records of medical and health institutions at all levels; Understanding of the implementation of prevention and control measures in each affected area. Results Before the earthquake, the epidemic areas carried out various control measures to varying degrees each year, with the incidence decreasing but still hovering at a high level. In the year of the earthquake, a large range of measures to kill dogs and repeated use of insecticides , The number of cases has been reduced compared with that in previous years; the following year after the earthquake, the number of incidences increased as compared with the year of earthquakes due to the relaxation of prevention and control work. Conclusion The ecological environment and living environment of the affected area have greatly changed after the earthquake. The source of infection, the media, the susceptible population and the natural and social factors still exist in the affected area after the earthquake. The risk of outbreak and epidemic still needs to be Doing a good job in killing dogs and exterminating malaria, strengthening the consultation and monitoring of kala-azar, carrying out the killing of dogs infected with Leishmania and the knowledge of prevention and treatment of kala-azar. During the disaster period, the risk of kala-azar could be controlled within a certain range .
