Prevalence of PTB among patients presenting with cough of any duration.

      Аннотация: A total of 725 (302 patients with cough of two or more weeks and 423 patients with cough less than 2 weeks) were recruited. Using smear microscopy, a total of 36(5.0%) cases of pulmonary TB were identified. The prevalence of smear positive pulmonary TB among patients with cough lasting two or more weeks was significantly higher compared to those patients with cough lasting less than two weeks (10.9% versus 0.7%; ?2 = 38.98; p = 0.001). The current smear microscopy and duration for two weeks for the diagnosis of PTB would affect early diagnosis and treatment in a considerable number of TB patients who reports cough for less than two weeks.
