本文报告广西1984年基本消灭丝虫病后,于1985～1989年在全自治区范围内进行的病原学、昆虫学和血清学监测结果。人群微丝蚴率和密度逐年下降,分别由1985年的0.007%和12.7mf/60μl,下降至1986年的0.002%和6.5mf/60μl,1987～1989年连续3年未发现微丝蚴血症者;1986～1989年对致倦库蚊、嗜人按蚊和中华按蚊进行监测,均未发现幼丝虫阳性蚊;血清学监测流行区人群平均丝虫抗体阳性率(IFAT)为1.53～4.21%。与非丝虫病流行区抗体水平相近,表明广西已有效地阻断了丝虫病的传播。
This paper reports the results of etiological, entomological and serological surveillance conducted within Guangxi Autonomous Region from 1985 to 1989 after basically eliminating filariasis in Guangxi in 1984. The population microfilariae rate and density decreased year by year, from 0.007% and 12.7mf / 60μl in 1985 to 0.002% and 6.5mf / 60μl in 1986 respectively. Microfilaria did not occur for three consecutive years from 1987 to 1989 ; From 1986 to 1989, Culex pipiens quinquefasciatus, Anopheles anthropophagus and Anopheles sinensis were monitored, no positive mosquitoes were found. The average prevalence of filarial antibodies (IFAT) in serogroups was 1.53 ~ 4.21%. Similar to non-filariasis epidemic area antibodies, indicating that Guangxi has effectively blocked the spread of filariasis.
