Unfortunately, the relatively low sensitivity of sputum smear microscopy - even more so in the presence of HIV co-infection - is a major drawback to case-finding.

不幸的是，痰涂片镜检的敏感性相对较低，对于合并感染艾滋病毒的患者则更低，这是病例发现方面的一个重大障碍。

The smear-positive case detection rate within established DOTS areas remained stable at an average of 51% up to 2001, but increased to 64% in 2004.

到2001年，已开展DOTS地区内的痰检阳性病例检出率稳定在平均51%的水平，但是2004年却增长至64%。

Through this approach, the project achieved 100% DOTS coverage, 77% case detection and a 92% cure rate for detected TB smear-positive patients.

借助这一疗法，项目下DOTS疗法覆盖率达到了100%，病例发现率达77%，结核病痰涂片呈阳性患者的治愈率达92%。
