１９８９～１９９６年，用ＬＤＴ和ＩＦＡＴ对山东（１３个市）、江苏（４个市）和安徽（３个县）３省原黑热病流行区人群进行免疫学监测。１９８９～１９９０年，山东省３０岁以下人群ＬＤＴ无１例阳性，３０岁以上人群阳性率平均为４．４％。１９９１～１９９２年，江苏省１０岁以下人群有ＬＤＴ阳性者，但３０岁以下和以上人群ＬＤＴ阳性率有显著差异（Ｐ＜０．０１）。１９９６年对江苏省人群进行动态监测，１０岁以下人群已无ＬＤＴ阳性者，３０岁以下和以上人群ＬＤＴ阳性率有显著差异（Ｐ＜０．０１）。３省受检血样本，ＩＦＡＴ均为阴性。结果表明，中国东部原黑热病流行区的山东、江苏、安徽３省黑热病防治效果巩固。
From 1989 to 1996, LDT and IFAT were used to immunologically monitor the populations in the endemic areas of Hara in Shandong Province (13 cities), Jiangsu (4 cities) and Anhui (3 counties). From 1989 to 1990, none of the LDT patients in Shandong Province under the age of 30 was positive, while the positive rate was 4.4% in those over 30 years of age. From 1991 to 1992, there were LDT-positive persons under 10 years of age in Jiangsu Province, but there was a significant difference (P <0.01) in the positive rate of LDT among those under 30 years of age and above. In 1996, the population of Jiangsu Province was monitored dynamically. No LDT was found in those below 10 years of age. There was a significant difference (P <0.01) in the positive rate of LDT among those under 30 years old and above. 3 provinces were tested blood samples, IFAT were negative. The results showed that the curative effect of kala-azar in Shandong, Jiangsu and Anhui provinces in the endemic areas of the original kala-azar in eastern China was consolidated.
