TB remains a significant public health issue, particularly in areas without effective treatment strategies like DOTS.

3.8 million TB cases were reported to WHO in 1996.
Acquired multidrug-resistant TB was present in 27% to 54% of culture-positive TB cases from the Baltic countries and Russia.
HIV seroprevalence among TB cases in Africa is 50% to 70%.
Treatment success in areas using DOTS rose from 76% in 1994 to 78% in 1995.
35% of health-care workers in Thailand tested positive for TB at the 15-mm cutoff.

TB is a big problem in many places, especially where there aren't good treatment programs. We need to help more people get treated.

The study used surveillance data from 212 countries and a survey of drug resistance in 32 countries to assess TB treatment outcomes.

The study may not fully capture the situation in countries with inadequate reporting or where DOTS is not implemented.

The study included data from various countries, focusing on both native-born and foreign-born populations affected by TB.
