The objective of this study was to identify the risk factors of pulmono tuberculosis related to housing covering the quality of walls, floor, ventilation, lighting, humidity and house occupant density. A case-control design was applied in this study with pulmono tuberculosis patients (78 cases)and their neighbours (non cases) having the same sex and age acting as control. Odds ratio calculation was applied to measure the strength of risk factors. with Mantel-Haenzel formula for significaney test (ct.< 5%). The findings showed that the intensity of lighting of living room (OR= 5.16)and bed room (OR = 6.24); and glass roof-tile (OR = 5.22) on the bed room were identified as risk factors for pulmono tuberculosis incident. Based on those findings, it is suggested that every room should have glass-roof-tiles. Keywords: Pulmono tuberculosis, housing, case-control, odds ratio
