摘　　要：目的调查葫芦岛市首例人附红细胞体(附红体)病病例,了解病程经过;对当地居民人、畜感染状况及影响因素进行调查分析。方法血涂片、镜检人、畜附红体感染状况,血细胞分析仪检测人贫血状况,诱蚊灯法监测室内外蚊种及密度,用病例对照方法对感染影响因素进行调查分析。结果人附红体感染率为30.67%,人群感染率性别、年龄间差异无统计学意义(χ2=1.79,P>0.05;χ2=1.05,P>0.05);猪感染率为60.87%;蚊虫密度较高,优势蚊种为刺扰伊蚊和库蚊;人群中有贫血症状者主要为低年龄儿童;养猪者感染附红体的危险性是不养猪者的3.77倍,喂食猪并接生者的感染危险性是仅喂食者的3.97倍。结论附红体病病例居住地人、畜感染率较高;发病人群以低年龄人群为主;猪是重要储存宿主,养猪为危险因素;蚊虫是重要的传播媒介。Objective To assess the course of the first case of human eperythrozoonosis in Huludao city and to determine the current infection situation and influential factors in humans and animals. Methods Blood smears were examined under microscope to determine the infection in humans and animals, blood analyzers employed to detect anemia in humans. Types and density of mosquitoes were analyzed using outdoor light traps. A case-control study followed to identify the influential factors for infection. Results The overall infection rate of eperythrozoon in humans was 30.67% without noticeable significant difference between men and women or among different age groups （χ^2=1.79, P〉0.05; χ^2= 1.05, P〉0.05）. The infection rate of eperythrozoon in swine was 60.87%. High density of mosquitoes was detected as Aedes vexans and Culex dominated. Anemic symptoms were primarily present in younger children. An excess risk for eperythrozoon infection was noted in swine breeders 2.77 times higher than in others, and the risk in those breeding and delivering swine was 2.97 times higher than pure breeders. Conclusion High prevalence of eperythrozoonosis was found in both humans and animals in the area, children constituting the major victims. Swine were the important reservoir host, breeding swine the risk factor and mosquitoes the transmission medium.
