In this Article
Is XDR TB a problem in the United States?
The risk of acquiring XDR TB in the United States appears to be relatively low. However, it is important to acknowledge the ease at which TB can spread. As long as XDR TB exists, the United States is at risk and must address the threat.
How many cases of XDR TB have been reported in the United States?
In the United States, 49 cases of XDR TB have been reported between 1993 and 2006.
Is it safe to travel where cases of XDR TB have been reported?
Although MDR and XDR TB are occurring globally, they are still rare. HIV-infected travelers are at greatest risk if they come in contact with a person with MDR or XDR TB.
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.
Air travel itself carries a relatively low risk of infection with TB of any kind.
What can health care providers do to prevent XDR TB?
Health care providers can help prevent MDR and XDR TB by quickly diagnosing cases, following recommended treatment guidelines, monitoring patients' response to treatment, and making sure therapy is completed.
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.
