The re-sults obtained in Little Kinmen included be-fore and after filariasis control by commonsalt medicated with diethylcarbamazine (DEC).It also compared the data obtained in twin is-lands of Kinmen Proper and Little Kinmenby combined method and medicated salt respec-tively. 1. Parasitological investigations：4,794persons in 14 villages of Little Kinmen wereexamined, the infection rate of 9.6% andmf. density/20 cmm blood of 14.4 were foundbefore filariasis control. The correspondingfigures were 0.2 % and 1.8 respectivelyamong 5,152 persons in 26 villages afterfilariasis control. In Kinmen Proper before filariasis control,the mf. rate of 8.4% and mf. density of14.6 among 45,787 persons in 129 villages.After control the corresponding figures were2.7% and 5.0 respectively among 37,596inhabitants. 2. Entomological investigations：On dis-section, 77 out of 844 Culex p. fatiganswere found positive, giving the infection rateof 9.1%；infective rate, 3.7%；and filariallarval density/ infected mosquito, 6.2. Thecorresponding figures after control were 0.8%,0.2% and 1.3 respectively in 504 Culex p.fatigans. In Kinmen Proper before filariasis con-trol, the infection rate of 10.3%；infectiverate, 6.4%；and filarial density/infectedmosquito, 6.4 among 3,220 C.p. fatigans.After control the correspndding figures were2.3%, 1.0%, and 3.0 respectively in 2,930C.p. fatigans· 3. Comparison of considerable factorsfor filariasis control by combined method andmedicated salt with DEC on Kinmes Islands；Based on the results obtained in KinmenProper after filariasis control by combinedmethod of chemotherapy (DEC) and larvicide(sumithion), the figures showed that thepersonal medication rate (88.6%) cure rate(80.1%), mf. reduction rate (96．7%),mosquito infected reduction rate (77．5%), and infective reduction rate (84.1%) weremuch lower than that in Little Kinmen afterfilariasis control by DEC medicated salt(100%, 98.5%，99.8%，91.2 % and 94.6%respectively). But the time spent (5 years),side-effects(61.6%)，excuses(3.1%)，andrefusals (1.6%) in the former were muchhigher than that in the latter(about threeyears, 0%, 0%, and 0% respectively).Moreover, the combined method has no treat-ment to the missed filarial carriers andalso no preventative value. Therefore，themedicated salt seems one of the most efficientsand practical method for use in filariasis con-trol in the future.
