1982年以来,对以嗜人按蚊为主要媒介的马来丝虫病流行区防治后期的流行动态进行了观察。纵向观察8个村,其中3个村于1985、1987、1988年进行普查,微丝蚴率由1.0％下降至0.14％,嗜人按蚊幼丝虫阳性率由0.74％(1984年)降至0.09％(1990年);另5个村于1987、1988年分别普查6148和5496人,1990年复查原微丝蚴血症者368人,未发现微丝蚴阳性,1982—1991年解剖嗜人按蚊17693只和中华接蚊7914只,亦未发现幼丝虫感染蚊。横向监测17个县855个村,9年间(1982—1991)共血检213934人,检出微丝蚴血症56例,其中53例为1986年以前检出,1987、1988年分别检出1例和2例,1989—1991年未再检出微丝蚴血症者。认为通过较大区域的防治使微丝蚴率降至1％以下后,以嗜人按蚊为主的病区,微丝蚴率未见回升,马来丝虫病传播流行呈下降态势。
Since 1982, the epidemiological status of the prevention and control of the endemic areas of Malayan filariasis, which is dominated by Anopheles anthropophagus, has been observed. Longitudinal observation of 8 villages, of which 3 villages in 1985, 1987, 1988 for census, microfilariae rate decreased from 1.0% to 0.14%, the positive rate of Anopheles mosquito larvae decreased from 0.74% (1984) 0. 09% (1990). The other 5 villages surveyed 6148 and 5496 people in 1987 and 1988, respectively. In 1990, 368 people with original microfilaremia were retrospectively examined. No microfilariae were found. 17693 Anopheles and 7914 mosquitoes were caught in China. Nematode insects were not found to be infected by mosquitoes. Lateral monitoring of 855 villages in 17 counties, nine years (1982-1991) a total of 213,934 blood tests, detection of microfilaremia 56 cases, of which 53 were detected before 1986, were detected in 1987,1988 Cases and 2 cases, 1989-1991 no further examination of microfilariaemia. It is considered that the microfilariae rate did not increase and the spread of malayian filariasis showed a downward trend after the microfilariae rate was reduced below 1% through prevention and treatment of a large area.
