１９９５—１９９６年在湖北省的江陵、仙桃两县市进行低疟区简化病例侦查方法的研究。结果显示：每个发热病人的血检费用为１．７８元，以二热病人为血检对象的简化病例侦查方案，原虫检出率为９．４５％，一次血检检出的阳性人数占总阳性人数的９５．３８％，检出每个阳性病例的费用为１８．８６元，而以四热病人为血检对象则费用要增加１８０倍，且两种病例侦查方案在降低疟疾发病方面无显著性的差异，同样可以取得较好的防治效果。从流行病学和卫生经济学综合评价，在以中华按蚊为唯一媒价的低疟区，以二热病人为血检对象的病例侦查方案，大幅度减少了血检数量，提高了措施的针对性，可以巩固疟疾防治成果，节省大量的人力、物力和财力，是经济有效，切实可行的优选方案
1995-1996 In Jiangling and Xiantao counties and cities in Hubei Province, a study was conducted on simplified case detection methods in low malaria areas. The results showed that the cost of blood test for each febrile patient was 1.78 yuan. The simplified case investigation program with two febrile patients as blood test showed that the detection rate of protozoa was 9.45%. The positive number of blood samples was 95.38% of the total positive number, the detection of each positive case costs 18.86 yuan, while the quadruple-patient blood test for the object is to increase the cost 180 times, and two cases of detection programs to reduce the incidence of malaria No significant difference, the same can get better control effect. From the comprehensive evaluation of epidemiology and health economics, in the low malaria area where Anopheles sinensis is the only media, the case detection program with two fever patients as the target of blood test drastically reduced the number of blood tests and improved the measures Targeted, can consolidate the results of malaria control, saving a lot of manpower, material and financial resources, is a cost-effective and practical options
