1989～1992年用LDT和MAT对山东和江苏两省17个地区(市)、38个县(区)的134个乡(镇)人群进行免疫学监测。山东省30岁以下人群LDT无1例阳性,30岁以上的人群阳性率平均为4.4％,显示山东省黑热病的传播早已得到有效控制。江苏省LDT阳性者最小年龄为8岁,1～9岁年龄组LDT阳性率是各年龄组中最低的,其中1～7岁1 409人无1例阳性,30岁以下与30岁以上人群平均阳性率分别为2.2％和9.0％;非流行区各年龄组人群LDT均为阴性,显示江苏黑热病的传播亦已得到有效控制。两省受检人群IFAT均为阴性。
From 1989 to 1992, LDT and MAT were used to immunologically monitor 134 townships in 17 districts (cities) and 38 counties (districts) of Shandong and Jiangsu provinces. There was no positive LDT in Shandong population under 30 years of age, and the average positive rate of 4.4% in those over 30 years old showed that the spread of kala-azar in Shandong Province had already been effectively controlled. The minimum age of LDT positive persons in Jiangsu Province was 8 years old. The positive rates of LDT in the age group of 1 to 9 years old were the lowest in all age groups, of which 1 409 cases were positive in 1 to 7 years old and 30 years old and above 30 years old The positive rates were 2.2% and 9.0% respectively. LDT was negative in all age groups in non-endemic areas, indicating that the spread of kala-azar in Jiangsu has also been effectively controlled. IFAT in both provinces was negative.
