【摘要】 目的　为了制定针对性的疟疾防治对策。　方法　根据江苏省疟疾流行因素 ,将流行区分为 6个监测组 ,即中华按蚊和嗜人按蚊共存地区 (1组 )、嗜人按蚊分布毗邻地区 (2组 )、中华按蚊单一媒介地区 (3组 )、基本消灭疟疾地区 (4组 )、流动人口较集中地区 (5组 )、献血员疟疾较多地区 (6组 )。于 1997～ 1999年分别在上述地区 ,对疟疾进行了分类监测。　结果　 1组疟疾年发病率、API、发热病人血检阳性率和 IFA阳性率均显著高于其它组 ,发病数占全省病例总数的74.38% ,嗜人按蚊占按蚊总数的 3.73% ;2组年发病率、发热病人血检阳性率、IFA阳性率明显高于 3～ 6组 ;3组和 4组年发病率、发热病人血检阳性率、IFA阳性率已降至较低水平 ;5组流动人口发热病人血检阳性率和 IFA阳性率显著高于当地居民 ;6组疟疾疫情已得到有效控制。　结论　 1组地区是江苏省疟防重点地区 ,2组地区需加强疟疾监测 ,3～ 4组地区可进一步简化现有抗疟措施 ,5组地区重点开展流动人口监测 ,6组地区可列入当地常规监测更多还原

【Abstract】 Objective To formulate the malaria control strategy with special measures. Methods Based on the factors for malaria transmission, a total of 6 surveillance groups were classified in malaria endemic areas of Jiangsu Province, such as Group 1: Cohabited region both with Anopheles sinensis and An. anthropophagus; Group 2: Peripheral region of An. anthropophagus; Group 3: The region distributed with An. sinensis only; Group 4: Effectively controlled region for malaria; Group 5: The region with higher mobile population; Group 6: The region with more blood donors infected with malaria. The malaria surveillance was done in different regions as above from 1997 to 1999. Results The prevalence, API, positive rate of blood test, and positive rate of IFA in Group 1 were higher than those in other Groups, accounting for 74.38% of total of malaria cases in the Province, and the population of An. anthropophagus accounted for 3.73% of total Anopheles population. The prevalence in Group 2 was fluctuated with the annual prevalence, positive rates of blood test or IFA significantly higher than those in Group 3,4,5,6. While the annual prevalence, positive rates of blood test or IFA in Group 3 and Group 4 were at a lower level. In Group 5, the positive rates of blood test and IFA in mobile population were significantly higher than those in local residents. The malaria transmission in Group 6 has been effectively controlled. Conclusion It is the key region for malaria control in Group 1, the surveillance measures are still need to be strengthened in Group 2, the control measures can be further simplified in Group 3 and Group 4, special attention should be paid to mobile population in Group 5, and regular surveillance can be applied in Group 6.更多还原
