In Tanjung Bayur Orchard found 17 cases 13 chronic cases (MF Rate 17,8 %) and in 4 cases had death. Tanjung Bayur is marsh area and most of consist marsh, there are rice field , ditch, water plant which can be prepared as growing vector place. Target, to know risk factor that influence fillariasis. Research reason is to give risk factor information that dominant to fillariasis disease in Tanjung Bayur orchard, Sungai Asam Village. Method, this research used case control design or retrospective study with 13 cases and 27 control. Risk factor that include in this research is vector species, vector density, ditch, water plant, marsh, rice field, pool, underbrush, livestock cage, clothes hanging, temperature, dampness, lighting, existence of gauze at ventilation, wall construction, existence livestock in a home, habit to use curtain, habit to use remedy agains gnats, habit to stay out of the house in the night. Research location has done at Tanjung Bayur Orchard on Sungai Asam Village, District of Sungai Raya. Data analysis use univariat technique, bivariat technique with Chi-Square Test and multivariate technique with Logistic Regression Test. Research result, show us thats existence ditch variable (OR = 8,0 ; 95 % CI = 1,5 - 43,4), existence water plant variable (OR = 4,6; 95 % CI = 1,1 — 44,9) and habit to use curtain (OR = 0,04; 95 % CI = 0,006 — 0,23) is meaningful for fillariasis infection. Conclusion, existence of water plant (OR = 4,6; 95 % Cl = 1,1 — 18,7), is risk factor that the most dominant for fillariasis infection. Suggestion, the regular illumination from health worker for people to give information about environmental and fillariasis dangerous.
