A cross-sectional cell-to-cell survey was conducted in 18 of 22 prisons in Malawi to determine the period prevalence of smear-positive pulmonary tuberculosis (PTB). In each prison, prisoners were interviewed using a structured questionnaire. Prisoners with cough of >1 week's duration were investigated by sputum smear examination. Of 7661 prisoners, 3887 had cough of > or =1 week, of whom 3794 submitted three sputum specimens: 54 (0.7%) had smear-positive PTB. The prevalence of PTB was higher in large urban prisons (1.1%) than in district prisons (0.3%, P < 0.001). More needs to be done to improve TB control in urban prisons.
在马拉维的 22 所监狱中的 18 所进行了一项横断面细胞间调查，以确定涂片阳性肺结核（PTB）的现患率。在每所监狱中，都使用结构化问卷对囚犯进行访谈。有咳嗽持续时间超过 1 周的囚犯通过痰涂片检查进行调查。在 7661 名囚犯中，有 3887 名有持续时间超过 1 周的咳嗽，其中 3794 名提交了三份痰标本：54 名（0.7%）有涂片阳性肺结核。在大型城市监狱中（1.1%），PTB 的患病率高于地区监狱（0.3%，P <0.001）。需要进一步努力改善城市监狱中的结核病控制。
