Abstract BACKGROUND: Little is known about the prevalence of tuberculosis (TB) and HIV among TB suspects in primary health care units in Ethiopia. METHODS: In the period of February to March, 2009, a cross sectional survey was done in 27 health centers of Addis Ababa to assess the prevalence of TB and HIV among TB suspects who have > = 2 weeks symptoms of TB such as cough, fever and weight loss. Diagnosis of TB and HIV was based on the national guidelines. Information concerning socio-demographic variables and knowledge of the respondents about TB was collected using pretested questionnaire. RESULTS: Of the 545 TB suspects, 506 (92.7\%) of them participated in the study. The prevalence of both pulmonary and extra pulmonary TB was 46.0\% (233/506). The smear positivity rate among pulmonary TB suspect was 21.3\%. Of the TB suspects, 298 (58.9\%) of them were tested for HIV and 27.2\% (81/298) were HIV seropositive. Fifty percent of the HIV positive TB suspects had TB. TB suspects who had a contact history with a TB patient in the family were 9 times more likely to have TB than those who did not have a contact history, [OR = 9.1, (95\%CI:4.0, 20.5)]. Individuals who had poor [OR = 5.2, (95\%CI: 2.3, 11.2)] and fair knowledge [OR = 3.7, (95\%CI: 1.3, 10.4)] about TB were more likely to have TB than individuals who had good knowledge. CONCLUSION: In conclusion, the prevalence of TB among TB suspects with duration of 2 or more weeks is high. Fifty percent of the HIV positive TB suspects had TB. Case finding among TB suspects with duration of 2 or more weeks should be intensified particularly among those who have a contact history with a TB patient.
