本文报告四川西部藏区两型包虫病（Hydatidosis，HD）人群感染特点与分布趋势。在石渠县与甘孜县的8个调查点，采用以B超与X光检查为主，辅以Dot－ELISA与Eml8blot血清学试验的方法对3999人的检查结果，人群平均感染率4．03％。其中细粒棘蚴病（CysticEchinococcosis，CE）2．13％，泡球蚴病（AlveolarEchinococcossi，AE）1．90％。女性感染率略高于男性，性别分布无明显差异。年龄分布显示中老年是高发人群。CE患者平均年龄38．8岁，AE为45．6岁。在不同经济类型地区，纯牧业乡的病情尤为严重，牧区＞城区＞农区的这种趋势极为明显。职业分布显示牧民是高危人群，HD感染率达7．01％—13．53％。AE患者亦以牧民最多，石渠县与甘孜县牧民AE感染率分别达6．06％、4．46％。此外，人群中文盲及受教育程度低者患者较多，随着文化水平提高人群感染率逐渐降低的趋势明显。
This article reports the characteristics and distribution of infection in two groups of Hydatidosis (HD) in western Tibet. In Shiqu County and Ganzi County, 8 survey sites, using B-and X-ray examination, supplemented by Dot-ELISA and Eml8blot serological test method for 3999 people, the average infection rate of 4.03% . Among them, 2.13% of CysticEchinococcosis (CE) and 1.90% of Alveolar Epicococcosis (AE) were detected. Female infection rate slightly higher than men, gender distribution no significant difference. Age distribution shows that middle-aged and high-risk population. The average age of patients with CE was 38.8 years and AE was 45.6 years. In different types of economy, the situation in Chunmu Township is particularly serious. This trend in pastoral areas> urban areas> rural areas is extremely obvious. Occupational distribution showed that herdsmen were at high risk, HD infection rate was 7.01% -13.53%. AE patients also had the most herdsmen, AE infection rates of herdsmen in Shitou County and Ganzi County were 6.06% and 4.46% respectively. In addition, there are more patients who are illiterate and have a low level of education in the population.
