广西基本消灭丝虫病后的监测结果

SURVEILLANCE OF FILARIASIS IN GUANGXI AUTONOMOUS REGION

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 surviellance in areas where filariasis has been basically eradicated since1984 in Guangxi Autonomous Region.A five years(1985—1989)longitudinal surveillance by etiological,entomogical and serological methods was carried out.The results showed that the average microfrilaria ratewas further reduced from 0.007% in 1985 to 0.002% in 1986 and kept zero in later three consecutiveyears(1987—1989).The average density of microfilariae was reduced from 12.7mf/60μl in 1985 to 6.5mr/60 1 in 1986.No natural infection of filarial larvae in Culex pipiens quinquefasciatus,Anopheles anthro-pophagus and An.sinensis was found in 1986—1989.The average positive rate of filarial antibodies in inhab-Rants living in endemic area by IFAT ranged from 1.53% to 4.21%.There was no significant differencebetween the filarial antibody levels of inhabitants living in endemic area and non—endemic area.It was con-eluded that the transmission of filariasis in The Guangxi Autonomous Region was interrupted effectivelly.
