我们于1991-1993年以乡为单位首次进行了布病流行病学调查,现将三年的调查报告如下。 调查结果 一、调查对象 凡年龄在10-70岁的全作为调查对象。重点是与牲畜接触密切的布病高危职业人群。并按放牧50％,饲养15％,屠宰15％,兽医10％,其它人员10％的比例要求进行采样。 二、调查结果 (一)人群布病流行情况:本次全县共调查9个乡,39个行政村。共检查620人,阳性17人,感染率为2.74％;其中有临床症状12人,患病率1.93％。感染率及患病率最高为开放的片马口岸,分别达7.14％和5.12％。其次为洛本桌乡和老窝乡。 (二)流行特点: 1.布病感染率与性别关系:在监测的620人中,男性311人,阳性7人,感染率2.25％,患病5人,患病率1.6％;女性309人,阳性10人,感染率3.23％,患病7人,患病率2.26％。男女性别间感染率在统计学上无差异。 2.感染率与年龄关系:发病最大年龄50岁,最小年龄11岁。30-40岁组感染率最高3.77％,10-20岁组为2.29％,50岁以上组最低为1.08％,经统计学处理有显著性差异(P<0.05)。 3.感染率与职业关系:以饲养人员感染率最高,其次为放牧员。经统计学处理有显著差异(P<0.05)。 讨论与分析 一、不同地区布病感染率与感染率 本文报告了泸水县布病血清流行病学调查结果,全县1991-1993年共调查620人,阳?
We conducted the epidemiological investigation of brucellosis for the first time in 1991-1993. The report of the three-year investigation is as follows. Findings A survey of all 10 to 70 years of age as a whole survey. The focus is on high-risk occupational groups that have close contact with livestock. And by grazing 50%, feeding 15%, slaughter 15%, veterinarian 10%, 10% of other personnel required sampling. Second, the survey results (a) the prevalence of brucellosis: The county a total of 9 townships surveyed, 39 administrative villages. A total of 620 people were examined, 17 were positive, the infection rate was 2.74%; among them 12 were clinical symptoms, the prevalence was 1.93%. The highest infection rate and prevalence rate were at the open chipmao port, reaching 7.14% and 5.12% respectively. Followed by Los Township Table Township and Lao Wo Township. (B) of the epidemic characteristics: 1 brucellosis infection rate and gender relations: in the monitoring of 620 people, 311 were male, 7 were positive, the infection rate was 2.25%, the prevalence of 5 people, the prevalence of 1.6%; 309 women , 10 were positive, the infection rate was 3.23%, 7 people were sick, the prevalence was 2.26%. There was no statistical difference in infection rates between men and women. 2. Infection rate and age: the maximum age of onset of 50 years old, the youngest age of 11 years. The highest infection rate was 3.77% in 30-40 years old group, 2.29% in 10-20 years old group, and 1.08% in the group over 50 years old. There was a significant difference (P <0.05) by statistical analysis. 3. Infection rate and occupational relationships: the highest infection rate of feeding staff, followed by grazing. There was a significant difference by statistical analysis (P <0.05). Discussion and Analysis First, the prevalence and prevalence of brucellosis in different regions This paper reports the results of serological epidemiology of brucellosis in Lushui County. A total of 620 people were surveyed from 1991 to 1993 in the county,
