Abstract: | BackgroundLittle is known about the prevalence of tuberculosis (TB) and HIV among TB suspects in primary health care units in Ethiopia.MethodsIn 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.ResultsOf 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.ConclusionIn 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. |
