Average of intensity infection (average of eggs per gram of faeces) belongs to low intensity infection. Knowledge and practice about worm infection prevention of Ede ethnic in Ea Tieu is very low: 29.8% people does not rightly know of any harm, 24.6% people know one of the reasons is because of unclean food, 16.3% and another reason because of unclean hands with 16.3%, only 6.1 % people know the reason for hookworm infection.

Result: A cumulative infection rate of 93.45% was found, of which Ascaris: 85.85%, Trichuris: 24.52%, and hookworm: 18.92%. No different' infection rate was found between males and females but it was higher with ages. The prevalence of Trichuris and hookworm was higher in adults against children and higher with the older ages. The infection of Trichuris and hookworm in adults was higher than that in children. The single helminth infection rate was 82.17%, and mixed infection of two species was 15.9% and three species 0.43%. The helminth infection among Sinh MUD ethnic group: 97.2%, Thai ethnic group: 96.6%, La Ha ethnic group: 85%, Kinh ethnic group: 80.62%, and H'mong ethnic group: 45.96%.

Distribution of Sparganum mansoni in 7 species of terrestrial snakes in Wonju City was surveyed. All kinds of snakes were found to be served as intermediate hosts of this larval worm except Elaphe schrenkii which has already been recorded as important host. Authors believe that Zamenis spinalis was firstly recorded as intermediate host of Sparganum mansoni in Korea. Some aspects of infection status, host-parasite relations and sources of human infection were briefly discussed.
