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 investigate the cases of the first case of human eperythrozoon (attached to red body) in Huludao City and to understand the course of disease. The status and influential factors of infection of human and livestock in local residents were investigated. Methods Blood smear, microscopic examination, the presence of red body infection in pigs, the detection of anemia by hematology analyzer, mosquito lamp and mosquito lamp were monitored by mosquito lamp method. The case-control method was used to investigate the influencing factors of infection. Results The rate of infection with red body was 30.67%. There was no significant difference in the infection rate between the sexes and the age (χ2 = 1.79, P> 0.05; χ2 = 1.05, P> 0.05) The dominant and dominant mosquito species were to infect Aedes albopictus and Culex quinquefasciatus. Among those with anemia, the predominantly low-age children were infected with pigs. The risk of infection with pigs was 3.77 times that of pigs without pigs, The risk of infection was only 3.97 times that of those who were fed alone. Conclusions The incidence rate of human infection with red body disease is high. The prevalence of the disease is high in low-age population. Pig is an important storage host and pig raising is a risk factor. Mosquito is an important transmission medium.
