result sql = BACKGROUND : According to WHO estimates, tuberculosis case detection rate in Tanzania is less than 50% and this poses a major challenge to control tuberculosis in the country. Currently, one of the defining criteria for suspecting tuberculosis is cough for two weeks or more. We wanted to find out whether the prevalence of tuberculosis was different in patients who reported cough for two weeks or more, compared to patients with cough for less than two weeks.

METHODS : We conducted a cross sectional study in six health facilities in Dar es Salaam, between September and October 2007. All patients aged five years and above with cough were screened for pulmonary tuberculosis (PTB) by smear microscopy. Patients were divided into two groups, those who coughed for less than two weeks (<2 wks) and those who coughed for two weeks or more (> or = 2 wks).

RESULTS : A total of 65,530 patients attended outpatients department (OPD). Out of these, 2274 (3.5%) patients reported cough. Among patients who reported cough, 2214 (97.4%) remembered their cough duration. One thousand nine hundred and seventy three patients (89.1%) coughed for >/= 2 wks as compared to 241 (10.9%) patients who coughed for <2 wks. Of those who coughed for two weeks or more, 250 (12.7%) had smear positive PTB, and of those who had coughed for less than two weeks, 21 (8.7%) had smear positive PTB. There was no statistically significant difference in prevalence of smear positive tuberculosis among the two groups (Pearson Chi-Square 3.2; p = 0.074).

CONCLUSION : Detection of smear positive PTB among patients who coughed for less than two weeks was as high as for those who coughed for two weeks or more.
