本文报告了临沂地区基本消灭丝虫病后传播趋势的研究结果。证实人群微丝蚴阳性率呈逐年下降趋势，且一直维持在０．１％以下；阳性者血中微丝蚴密度最高条数１９８７年后已降至５条／１２０μｌ以下；基本消灭丝虫病后出生的人群未发现阳性者。蚊媒监测结果表明：淡色库蚊自然感染率由１９８４年的０．０３％至１９８８年已降为零。丝虫ＩＦＡＴ测定，其阳性率基本消灭前出生的人群明显高于基本消灭后出生的人群，二者有显著性差异。经实验研究证实：临沂地区动物丝虫未发现感染淡色库蚊及传播给人类。据以上监测实验结果认为：该地区基本消灭丝虫病后经过进一步的监测净化，已达到阻断传播水平。
This paper reports the results of research on the transmission trends after the basic elimination of filariasis in Linyi. Confirmed that the positive rate of microfilariae showed a declining trend year by year, and has remained below 0.1%; positive blood microfilariae in the highest number of lines after 1987 has dropped to 5 / 120μl or less; the basic elimination of filariasis After the birth of the crowd did not find positive. Mosquito vector monitoring results showed that: Culex pipiens natural infection rate from 0.03% in 1984 to 1988 has dropped to zero. IFMA determination of filarial, the positive rate was basically eliminated before the population was significantly higher than those born after the basic elimination of the crowd, there was a significant difference between the two. The experimental study confirmed that: Linyi animal filariasis did not find infected Culex pipiens pallets and transmitted to humans. According to the above monitoring experiment results, it is considered that: after the basic elimination of filariasis in the area has been further monitored and purified, the level of blocking transmission has been reached.
