根据１９８５、１９８７、１９８８和１９９６年４次在马来丝虫病观察区收集的数据，计算分析了人群传染性指数（ＩＴ），从１９８５年的０．１６２１％逐年减至０．０３０９％、０．０２６０％和０．００５８％；１９８７、１９８８和１９９６年分别较１９８５年减少８０．９４％、８３．９６％和９６．４２％。说明当地自１９８３年最后一次治疗病人终止防治措施以后，丝虫病的流行已得到进一步控制，原防治措施的效果肯定；但是个别高密度微丝蚴血症者仍然是防治后期一个潜在的威胁。
The infectious disease index (IT) of the population was calculated and analyzed from four data collected in the observation area of filariasis in 1985, 1987, 1988 and 1996, from 0.1621% in 1985 to 0.0309% 0.0260% and 0.0058%, respectively. Compared with 1985, they decreased by 80.94%, 83.96% and 96.42% respectively in 1987, 1988 and 1996. It shows that the prevalence of filariasis has been further controlled after the last treatment of patients was discontinued in 1983 and the effect of the original prevention and treatment measures has been confirmed. However, individual high-density microfilaremia patients are still a potential threat in the late stage of prevention and treatment.
