Because TB can be spread through the air by coughing, sneezing, or even talking, public health officials have suspected that person-to-person transmission of drug-resistant TB is occurring. But they haven't had the data to support that belief. This study, Shah said, provides "strong, incontrovertible" evidence that there needs to be more emphasis on halting transmission.
That means better infection and prevention control in hospitals, screening for sick people in the community and separating them from the general population, and promptly initiating treatment.

If TB bacteria are found in the sputum phlegm , the diagnosis of TB can be made in a day or two, but this finding will not be able to distinguish between drug-susceptible TB and drug-resistant TB.
To determine drug susceptibility, the bacteria need to be grown and tested in a specialized laboratory. However, TB can spread easily. All travelers should avoid high risk settings where there are no infection control measures in place.
Documented places where transmission has occurred include crowded hospitals, prisons, homeless shelters, and other settings where susceptible persons come in contact with persons with TB disease. Providers should also ensure proper implementation of infection control procedures to prevent exposure to TB in hospitals or health-care settings where TB patients are likely to be seen. This highly resistant form of TB was identified in every region of the world where there was lab capacity to identify it.
These factors have contributed to an apparent increase in drug-resistant TB because of better diagnosis and better reporting. CDC is collaborating with other federal agencies and international partners to raise awareness and enhance strategies for TB prevention worldwide by:.
